| We unscrew the regulators themselves. We disassemble the regulator by unscrewing the black plug at the top | |
| We take out the insides from the regulator | |
| The valve itself with the spring remains in the upper part. I was very surprised to see this plunger inside the regulator: the hole is approximately 0.5 mm in diameter, and this line is also strangled by this valve. No wonder why the wheels don't slow down! In general, there are two options: either remove the valve, or drill a hole to 1.5 mm in diameter. I decided to go the first route, especially if you don’t like it, you can always go back | |
| I cleaned all the insides, washed them, blew them out and put them back together. We throw away ONLY the plastic ball with the spring, and put everything else back together! I bled the brakes and went to test the brakes. I will say right away that I am 100% satisfied with the result. Now you really feel like ALL four wheels are braking! I read somewhere that after this procedure the rear wheels lock before the front ones. That's bullshit! The front ones brake earlier, as expected. PS Attention! Removing PTC valves is a change in the design of the car, namely one of the important systems - the braking system. This modification is not approved by the manufacturer and is performed by you at your own peril and risk. |
Brake system Daewoo Nexia: design, principle of operation, maintenance and repair
The Daewoo Nexia model is an example of a combination of a car that has outlived its age and new modern developments.
Every element of the car's design, including the brake system of the Daewoo Nexia, was copied by the company's engineers from the old Opel Cadet model.
These guys managed to change its appearance and make improvements in such a way that the resulting car is still relevant among car enthusiasts to this day.
The model turned out to be quite comfortable and almost fully satisfies the needs of a certain number of car owners. However, in this article we are not interested in the “heart” of the car, or even the interior, but in the design features of such a unit as the Nexia brake system, which we must understand.
General principle of the device
Each brake system of various car brands has one common operating principle - at the first press of the brake pedal, they reduce the speed of the car to the level desired by the driver. The generation of braking torque helps to cope with this responsibility, in which the force is inversely proportional to the force with which the wheels rotate and is directed at them at the place where the wheels come into contact with the road surface.
Each car model is developed in such a way that it has not just one brake system option, but several. Daewoo Nexia brake system consists of service, emergency and parking brake systems.
Operating principle of the parking brake system
Each of them must be considered separately. The parking brake system is responsible for keeping the car stationary during long periods of parking in one place. Among car enthusiasts, this system is called a hand or parking brake. It is the handbrake that is also an emergency option for braking the car in the event of a malfunction in the working brake system. Achieving immobility of the car using the parking brake is possible thanks to standard mechanisms that are installed on the rear axle of the model.
At the moment when the driver raises the parking lever, a special cable is tensioned, which fixes the rear wheels in a given position. The presence of a special ratchet in the design does not allow the handbrake to lower to its original position.
The working system is activated after the driver presses the pedal. Such brakes are designed to provide a systematic reduction in speed. It is impossible to use a parking system for these. But the handbrake can become an indispensable assistant when there is a need to move away while on a slope.
General rules for repairing the brake system of various car brands are described here. What is the brake system of the VAZ-2109 and what faults can most often be found in it, see here.
Operating principle of the system and working mechanism
The brake system diagram of the Daewoo Nexia is very unique. For this reason, it is better to divide it into a working mechanism and a drive, while each element must be dealt with separately.
The brake system of the Nexia model is equipped with both drum and disc brakes. This was done with the aim of completely or partially blocking the rotational movements of the car’s wheels.
The front axle of the model is equipped with a disc system, and the rear axle is equipped with a drum system.
A disc brake system consists of a caliper, pads and the brake disc itself. The support in this design is fixed above the rotating disk using a bracket.
The caliper has small grooves designed for working drive cylinders. In addition, the caliper contains pads that are pressed very tightly to the body using springs.
Each of these pads has special friction linings, which are made of a material that can withstand high friction temperatures.
The brake disc is screwed to the hub using bolts. This is done in such a way that it can rotate simultaneously with the wheels. During braking, the disc becomes very hot. To solve this problem, special ventilated discs are installed on the machines, with holes made on the surface.
The most expensive versions of the model can be equipped with discs that are made using ceramics and are more susceptible to the friction process. They also allow you to reduce the braking distance of the car to a minimum.
The operating principle of the drum mechanism is identical to the disk mechanism. However, the design features of this design are visible to the naked eye.
In this case, the working drive cylinders, together with the shoe mechanism, are located in the drum housing. The drum itself is very similar to a flat plate with large edges.
This part is installed on the hub and rotates simultaneously with it.
Inside there are pads that are supported in their original position by a spring. The working cylinders are also installed in the same place. The difference between the drum system pads and the same parts of the disk system is the wider plane section of the first option.
Drive mechanism
The Nexia model is equipped with a hydraulic drive, which means that the brakes are activated due to the pressure on the fluid in the circuit. The brake actuator plays an important role in the process of controlling the braking system of a machine.
When the driver presses the brake pedal, the first pressure is created, which is transmitted via a cable to the master brake cylinder, which has a vertical location.
In the design of the upper part of the cylinder there is an expansion tank, under which there is a piston that makes translational movements and pumps up the pressure in the brake circuit. The circuits in this braking system are located strictly separately: one is located on the front axle, the second on the rear.
When a person behind the wheel presses the brake pedal, this action is sensed by the brake cylinder and the valve closes. This sequence results in the liquid in the circuit being in a completely sealed state. Next, the piston begins to move down and creates pressure.
When it reaches the working cylinders, the latter begin to expand and, thereby, press the pads against the drum or disk, which leads to a decrease in the speed of the car.
When the driver takes his foot off the brake pedal, the system is put into a relaxing mode, in which the piston of the master cylinder rises to the top, and the valve opens and allows excess fluid to flow into the expansion tank.
To assist the driver in controlling the application of force when pressing the pedal, the brake system is designed to include a vacuum booster, the purpose of which is to create additional force on the piston. For this reason, the brakes begin to operate even from a very light touch of the pedal.
Replacement instructions
When replacing drum pads, all parts of the repair kit are changed.
- Put the car in first gear and lock the front wheels.
- Lower the handbrake.
- Remove the rear wheel.
- Pump out the brake fluid from the reservoir.
- Remove the brake drum.
- Disconnect the tension spring.
- Clamp the shank onto the support post with pliers, press on the washer and turn. The support strut and the front pad spring must be removed along with the shank.
- Remove the front trim and clearance adjuster.
- Remove the tension spring and the spacer bar.
- Pull back the rear cover.
- Remove the release lever from the handbrake cable.
- Remove the spring to adjust the gap.
- Remove the shackle and adjustment lever.
- Clean the spring, shackle and regulator lever. Install on new brake pads.
- Apply refractory lubricant to the friction points of the front and rear brake drum linings with the brake shield.
- Coat the threads of the strip with lubricant and tighten the nut.
- Compress the brake cylinder pistons using pliers. Install the brake linings.
- Install the brake drum.
- Press the brake pedal until the clicking noise stops. The gap between the drum and the brake linings is adjusted. The regulator makes clicking noises. The gap is considered set at the moment the clicks stop.
- Install the wheel.
The brake lining material contains asbestos fibers that are dangerous to humans.
Do not clean pad parts with dust-generating tools (dry brush, pad grinder, compressed air jet).
To remove dirt, use only a damp cloth.
The brake pads on the second wheel are changed in a similar way. After replacing the brake pads, you need to adjust the parking brake system.
Manufacturers also recommend replacing springs, support struts and spacer bars. The listed parts are not sold complete with pads. You need to take care of purchasing them separately.
Replacing rear pads on a Daewoo Nexia - replacing rear brake pads on a Daewoo Nexia n150
Replacement of rear pads on Daewoo Nexia is carried out infrequently, since when braking 70% of the load goes to the front ones. The problem with diagnosing brake pads on a Daewoo Nexia is that they can only be examined after removing the brake drum. Brake failure is a dangerous failure. If the pad comes off the pad, the wheels can lock even at high speed. For this reason, more and more car manufacturers are no longer installing drum brakes, but they are still used on Daewoo Nexia.
Replacement frequency
No one can say for sure after what period it is worth replacing brake pads, since it depends on a large number of conditions:
- Quality of the lining;
- Condition of the brake drum and cylinder;
- Serviceability of the sliding mechanism;
- Vehicle operating conditions;
- Driver's driving style.
Attention! If the drum is severely damaged, the pads will quickly fail.
Brake pads can last 5-100 thousand kilometers. The service life depends on the above factors and luck. Therefore, their serviceability must be closely monitored. You can identify failing pads by the sound from the brake drum, as well as by the intensity of braking.
Pad selection
- At the moment, there are no problems with choosing and purchasing pads, since pads suitable for Daewoo Nexia are found on a large number of cars: Daewoo Lanos, Espero, Nubira, as well as on some budget Chevrolet models, which are descendants of the Opel Kadett.
- The advantage of drum brakes is their cost and ease of maintenance.
- Some models of brake pads, sorted by descending price:
- The highest quality and most expensive are Ferodo FSB-335. These German-made pads are popular in Russia, although they do not sell very well. The price is about 5 thousand rubles.
- Another German model is Zimmermann. They cost 4 thousand rubles, which is twice as expensive as the original ones.
- Factory pads Hi-Q SA-055 from a Korean manufacturer. The quality is not much inferior to their German counterparts, but they cost only 2 thousand.
- Onnuri is also a Korean model, but costs a little less – 1.5 thousand.
- Rider is a model from a Hungarian company. The cheapest on this list.
Prices are approximate.
They may vary in different regions of the country, and also become more expensive/cheaper over time.
When dismantling old brakes, it may turn out that it is not only the pads that need to be replaced. It will not be superfluous to buy a complete repair kit, which includes almost all components of the brake mechanism. It costs around 500 rubles.
Tools necessary to replace rear pads on Daewoo Nexia n150
- Wheel chocks;
- Two jacks;
- A set of spanners and heads for them;
- Pliers (if available, it is recommended to use long-nose pliers);
- Mild steel hammer;
- Screwdrivers; WD-40;
- Silicone grease resistant to high temperatures.
Replacing rear brake pads on Daewoo Nexia
Dismantling algorithm
- For convenience, use a viewing hole or drive the car onto a lift.
- Install wheel chocks on the front wheels.
- Apply lubricant to the rod and loosen the parking brake cable tension nut.
This is done in two ways: using a socket with an extension or removing the heat shield. - Using a jack, raise the car on both sides so that the rear does not touch the ground.
- Remove the wheel by unscrewing the mounting bolts.
- Disconnect the hub cap and unscrew the nuts.
- Unscrew the countersunk screw and remove the drum. If you can't remove it, carefully knock the drum down with a hammer.
- Important! Before disassembling the mechanism, remember the location of all parts!
- Disconnect the spring from the adjusting device and from the support post by rotating the cup 90 degrees while holding the support post.
- Remove and clean the support post.
- Disassemble the mechanism on the second side in the same way.
- Disconnect the tension spring from the top. First from the front block, then from the rear.
- Move the pads apart from above and unhook them from the handbrake cable.
- Take them out and inspect their condition.
- Clean the shield from dirt and corrosion, apply lubricant.
Assembly algorithm
Important! Replace the springs with new ones, if possible. If there are defects on the springs, then it is unsafe to put them back.
The assembly algorithm resembles the dismantling algorithm in reverse order.
- Start connecting the new block to the rear of the handbrake cable.
- Secure it with a tension spring.
- Return the cleaned support post and its spring to its place; to install the post, you need to turn the bowl 90 degrees again.
- Attach the front block.
- Secure it with a holding post and a spring with an automatic closing mechanism.
- Check for correct assembly.
- Lubricate the hub and replace the grease in the bearing.
- Install the drums and wheels.
- Press the brake pedal several times until the parts of the mechanism are in the desired positions.
- Adjust the handbrake.
Attention! Remember to lubricate moving parts that require lubrication, such as the hub or bearings. The lubricant must be resistant to high temperatures.
Check the drums carefully for wear. If you install new parts in worn drums, their service life will be noticeably reduced.
Remove the side of the excavation if you are installing old drums. And if the surface wear is more than 20 centimeters, the brake drums also need to be replaced.

How to bleed the brakes on a Daewoo Nexia: procedure and bleeding scheme
The braking system of the Daewoo Nexia is not much different from similar systems in small class cars. However, there are some nuances that should be taken into account when servicing and repairing Nexia brakes. Today we will figure out how to bleed the brakes on a Nexia and find out all the intricacies of this issue.
When the brakes are pumped on a Daewoo Nexia
Naturally, the first signal of a malfunction in the brake system will be an inadequate response of the car to pressing the brake pedal.
Before bleeding the brakes, it is worth remembering the last time the brake fluid was changed.
The pedal may feel weak or sink almost to the floor, but there will be no effective deceleration. It is also worth looking at the brake fluid level warning lamp in the reservoir. A burning lamp will indicate that air has most likely already entered the system.
After any repair of the brake cylinders, main or wheel, it will also be necessary to bleed the brakes..
The ultimate goal of the operation is to completely remove air from the system or completely replace the brake fluid.
When fluid leaks, air can also enter through leaks in the brake lines and worn brake cylinder seals. In short, pumping technology will come in handy more than once.
Necessary tool
Socket wrenches for 10 and 12 with cutout. New brake fluid.
For this work, we will need a union wrench (socket wrench with a cut out segment), a transparent tube about 50-70 cm long, a transparent container for draining waste fluid, and new brake fluid.
Pumping scheme
When bleeding the system, we will remove air from each circuit and from each working cylinder in strict order:
- Right rear wheel.
- Left rear wheel.
- Right front wheel.
- Left front caliper.
In the event that we repaired only one caliper or one working cylinder, most likely there is no need to bleed the entire system.
It will be enough to remove air only from the cylinder being repaired. Before starting work, do not forget to unscrew the reservoir cap and add fluid to the maximum mark. In addition, during the pumping process, we will monitor the liquid level in the tank and will not allow it to be more than half empty.
Before pumping, add brake fluid to the expansion tank using a syringe or bulb.
Pumping technology
If the car is equipped with an ABS system, then bleeding begins by turning on the ignition and pressing the brake pedal five times. After this, fresh liquid is added to the tank if necessary. When bleeding air from the rear cylinders, the ignition must be turned on. This is necessary so that the ABS hydraulic pump is activated and creates pressure in the circuit.
Otherwise, the pumping technology is no different:
- We ask the assistant to slowly press and release the pedal until it becomes elastic with maximum pressure resistance, the pedal is held in this position.
- Remove the protective cap from the fitting of the rear right cylinder, put a tube on it and lower it into a container half filled with liquid.
We clean the rear fitting from dirt and put the tube on it. - We unscrew the fitting 1/2 turn, at this time the pedal falls. An assistant holds it in this position until we tighten the fitting.
- We repeat pumping the cylinder until air bubbles stop coming out of the tube.
Bleed the brake cylinder until all the air is released. - An assistant holds the pedal in the lower position, at this time we tighten the fitting with a force of about 10 Nm and put on the protective cap.
- Using the same technology, we pump the remaining cylinders in the specified order.
At the same time, do not forget to monitor the fluid level in the tank. We pump the remaining cylinders according to the order.
After pumping
After bleeding, add new brake fluid to the maximum level and close the reservoir with a lid.
We control the level of brake fluid in the expansion tank.
There are several nuances - when pumping, you need to press the pedal slowly and smoothly. Smoothly pressing the pedal eliminates the formation of emulsions (small air bubbles). The emulsion in the form of foam is almost impossible to dislodge from the system in the usual way. This is why pressing the pedal smoothly and slowly is of great importance.
Important nuances
And one more important detail - between pumping cycles you need to pause for 20-25 seconds.
Time is needed for air bubbles to rise to the top point of the working cylinder (to the fitting) and be displaced by fresh fluid. By following these instructions, you can effectively remove air from the brake system or completely replace the fluid. Good luck to everyone and strong brakes!

Types and properties of fuel fluid
Any brake fluid has 93-98% of the main composition and from 2 to 7% of additives, which, in fact, are the key component for imparting the declared characteristics. In general, if you look at it this way, the properties of brake fluid depend on the combination of its components. Depending on the composition of the base, TJ is divided into 3 groups.
Types of brake fluids:
- Mineral (mineral oil LHM). They consist of alcohol and castor oil.
- Glycolic. Developed on the basis of polyglycols and their esters.
- Silicone. Manufactured from silicon-organic polymer products.
Regardless of the type and composition, all brake fluids are divided into two classifications.
TJ classification:
- By viscosity.
- By boiling point:
- for “dry” liquid (without water);
- “wet”, which contains 3.5% water.
If the boiling point exceeds the permissible norm, then there is a risk of a vapor lock forming in the system (as a result of moisture evaporation), which can lead to breakdown and failure of the brake pedal.

Pad selection
The choice of rear brake pads for Lanos should be approached carefully, because not only braking while driving, but also how the parking brake will work depends on them.
96226110 – this is the original catalog number of the Chevrolet Lanos rear brake pads. The average cost in the Russian Federation is 2000 per set.
There are quite a lot of manufacturers that produce analogues, but we will consider only those that, based on experience, are installed by car owners.

General principle
The braking system of any car has its own purpose, and is to reduce the speed of the car as quickly and effectively as possible until it comes to a complete stop at the request of the driver. This happens due to the generation of braking torque, the force of which is the opposite of the rotational force of the wheel and acts on it at the point at which the wheels come into contact with the asphalt.
Any car is designed to have several braking systems, the Daewoo Nexia includes the following:
- Parking lot.
- Emergency.
- Working.
We will consider them in order. The parking brake system is responsible for keeping the car stationary when parked for long periods in one place. It is usually called the handbrake, and it is also an emergency one. If the working brake system fails, pulling the handbrake in time means trying to save your life and everyone who is driving in the same car with you. A stationary state is achieved through standard brake mechanisms that are used on the rear wheels of the Daewoo Nexia.
When the driver pulls the lever, he pulls a special cable that clamps the rear wheels and fixes them in this position. And a special ratchet prevents the lever from going down. The working system is activated by pressing the pedal and is the main one; when driving, it is most often used. This braking system can provide a smooth reduction in the speed of the Daewoo Nexia; it is impossible to use the parking system in this way. But the handbrake is very convenient to use when you need to start on a slope without rolling back. This may be necessary when there is a car behind you and rolling back can cause an accident.
Good luck on your journey.
: Do-it-yourself replacement of rear brake pads.
Something strange about your repair kit. I took one from the Opel Astra, one in the same with my family. But the worst problem is with the plates that fix the spring for pressing the pads to the shield; they are very flimsy. It's good that now you can buy them separately.
In this set the plates are just solid, but the lower spring is not so great, I left the old one.
I also changed the pads today... the result is that the handbrake is gone. What did I miss?
The handbrake is adjusted in two places: 1. Under the car, adjust the cable tension (located under the thermal shield of the resonator, unscrew 4 nuts, remove the shield and there is a 13 key nut there), tighten and release the rocker arm on which the cables are attached. 2. A mechanism for automatically adjusting the gaps between the pads and the drum (after assembling the brake mechanisms, you need to press the brake pedal several times, clicks should be heard until they stop) this is done by turning the adjusting nuts on the sliding spacer bars. The arm of the parking brake release lever rests on these same bars.
If the travel of the parking brake lever is normal (no more than 5 clicks), then the tightening of the cables is normal; if more needs to be tightened, but the parking brake still does not hold, then you should remove the drums and look at the adjusting nuts of the spacer bars. If the nuts remain fully tightened, then the automatic clearance adjustment mechanism did not work. (Re-read the article above and check the correct assembly). You can adjust it manually, rotate the nuts by the teeth with a screwdriver, periodically trying on the brake drum (so that it fits onto the pads with minimal clearance). There may also be a problem with the parking brake cables; it happens that in some places the shell is destroyed and, due to internal corrosion, the cable stops moving in it and, accordingly, tightens the release lever.
The handbrake works, I adjusted it with a ratchet. I made a minimum gap between the pads and the drum. The result is 5 clicks - the car stops. And the braking became better.
Everything is correct. Spacer bars and parking brake and the gap between the pads and the drum. It is necessary to ensure that the adjustment is carried out automatically.
In the bottom photo, signed “Assembled feed mechanism.” At the lever of the eyeliner mechanism there is a part, a plate made of spring steel bent in half with a hole, I sat and figured out what it was for, on one of the forums I found that it is a stop….
Ilya, there really is such a part in repair kits, but I didn’t find it in catalogs or “primer books”. How I installed this plate can be seen in the photo, I assume that it serves to press the double-armed lever away from the block so that it does not fall between the block and the spacer bar. If you have other opinions or information, please write.
Ilya, Sergey, in my opinion it needs to be placed on the spacer bar, putting the “male” on the fork after the leading nut. There seems to be a groove on the “mother” fork for the tail of this thing.
Sergey, when ordering one 94525222 we get 2 castle washers?
Yes, the set includes 2 washers.
Livingstone, I tried this part on the spacer bar, tried it in different versions, installed it in the way that seemed to me in the most optimal place, but I won’t say that this is the only correct option... If someone knows more, tell me, correct me.

Preparing for repairs
Before replacing the rear brake pads (Daewoo Nexia), be sure to perform the following manipulations:
- Place wheel chocks under the front wheels.
- Loosen the mounting bolts on the rear wheels.
- First jack up one side of the car, then the other. Your goal is to hang out the entire rear of the car.
- Remove the wheels.
- Remove the nuts that secure the rear brake drums.
- Carefully, trying not to damage, knock down the drums.
After carrying out these manipulations, you can begin replacing the rear brake pads
Your Daewoo Nexia will be like new! Pay attention to the inner surface of the drums - if it is uneven, you will need to sharpen the parts. This should only be done on a lathe.
After such an intervention, it is necessary to carry out balancing so that there is no axial runout after installation.
Replacement process
- Jack up the car and remove the front wheel.
- Using a screwdriver as a lever, separate the pads from the drum and, unscrewing the mounting bolts of the fingers, remove the “original” caliper.
- Regarding the brake hose: it is better to disconnect it while the “hydraulic vice” of the car is fixed. Take the hose into a pre-prepared jar (for dripping liquid).
- Then remove the pads along with the pressure plates. If the brake disc also requires replacement, remove it too.
- Next, using the repair kit, install new spare parts.
- Carry out the work in reverse order. To secure the hose, be sure to buy a new copper or aluminum washer, as it is compressed during operation.
The purchased kit also includes pads. Codes for purchase through Exist.ru: 96234339 and 96234340. A kit intended for the repair of Daewoo cars, consisting of pins, seals and brackets, made in China, goes under the code 93740249. The replacement occurs on the other side in a similar way.

If the nuts remain fully tightened, then the automatic clearance adjustment mechanism did not work. (Re-read the article above and check the correct assembly). You can adjust it manually, rotate the nuts by the teeth with a screwdriver, periodically trying on the brake drum (so that it fits onto the pads with minimal clearance). There may also be a problem with the parking brake cables; it happens that in some places the shell is destroyed and, due to internal corrosion, the cable stops moving in it and, accordingly, tightens the release lever.
