How to change brake discs in a Chevrolet Niva with your own hands: step-by-step replacement instructions

In our short article we will look at how to replace brake discs on a Chevrolet Niva. The brake system is the most important part of any car, because it allows you to stop traffic as quickly and safely as possible. Naturally, this affects road safety - the system allows you to avoid emergency situations. It is prohibited to operate vehicles with a malfunction of the braking system; this entails not only administrative punishment. After all, if this mechanism breaks down, you can get into an accident.

Replacing a brake disc on a Niva Chevrolet

The pads must be marked so that during subsequent assembly they can be installed in their places. Next, unscrew the bolt securing the protective casing.

Using small pliers or a flat-head screwdriver, bend the tendril of the locking plate of the upper and lower pad guide to the steering knuckle. A visual inspection may reveal the appearance of cracks, chips and other defects.

Replacing Niva front brake discs

To understand how bad the level of wear is, you may need a caliper. To do this, you need to compare the length of the new pads and those used in the car. If the difference is more than 3 millimeters, then you definitely need to remove the brake disc on a Chevrolet Niva. How to diagnose breakdowns? Before replacing the Chevrolet Niva brake discs with your own hands, you need to diagnose the entire system.

The fact is that tubes and hoses can also become unusable, and this also affects driving safety.

But let's get back to the pads and discs. Checking them for malfunction is quite simple: Pay attention to whether there are any extraneous sounds when braking - grinding, noise, jerking, and others. Are there any cracks, gouges, or chips on the surface of the disc? It is also necessary to carefully inspect the pads and check the thickness of the friction layer.

Installing ventilated discs

But what needs to be done when replacing brake discs on a Chevrolet Niva? Installing ventilated discs instead of standard ones is quite difficult; you will have to perform several costly manipulations:

1. Replace wheel rims. Instead of size R15 you will need to put R16.
2. Of course, you need to buy the discs themselves.
3. You will also need a new set of pads.
4. You still need to install new calipers and fasteners.

After installing all the elements, you can start operating the car. And do not forget to promptly check the condition of the brake mechanisms. If necessary, you need to replace the brake discs on the Chevrolet Niva. If the standard ones do not suit you, you need to install ventilated ones - they can not only eliminate overheating, but also significantly improve braking efficiency.

About wear of brake discs and its detection

Unfortunately, a car does not last forever and all parts fail sooner or later. Brake discs are no exception. And water and dust bring this part closer to unusability even faster.

The first sign of disc failure is braking problems . You will feel it even without technical inspection. But it’s best if your fears are confirmed at the service station.

If you don’t want to go to specialists, you can try to identify the problems yourself by paying attention to the following signs of brake disc wear:

• When braking, extraneous noises and the car moves jerkily;
• Cracks and grooves appeared on the part in the form of grooves around the disk;
• The detail shows severe wear.

If any of the above symptoms are present in your car, then you need to replace the front brake discs as soon as possible.

Replacing the brake disc

To replace, you will need to prepare a set of new brake discs in advance, since when replacing only one side, the brake system may not function properly. You will also need the following set of tools:

• a set of keys for 10, 14, 17 and 27. For more comfortable work, it is advisable to use a ratchet wrench.
• screwdriver
• pliers or round nose pliers
• jack
• hammer/mallet

The replacement itself is carried out in several stages.

For more comfortable work, it is necessary to perform all actions in a pit or viewing platform. If this is not possible, you need to place the car on a level surface and raise the front part with a jack.

After this, the bolts holding the wheels are unscrewed. The calipers are removed. In order not to disconnect the hoses suitable for them, you can secure them with wire. It is not recommended to leave the caliper hanging from the hose as they may require replacement if damaged.

The next step is to remove the brake pads. If their condition does not allow replacement, it is better to mark them so that they are installed in the same position.

To remove the old disk you need to unscrew the bolt holding the casing. Then, using a screwdriver, remove the locking plate antennae that secure the pad guides. The bolts holding the pads are unscrewed.

Tools for repair

When replacing brake discs on a Niva Chevrolet, you need to use a standard set of tools; no scarce equipment is needed.

List of tools:

• Socket wrenches, open-end wrenches, socket wrenches for 10, 14, 17, 27. If you use socket heads, it is inconvenient without a ratchet.
• Pliers.
• Screwdrivers.
• Hammer.
• Jack.
• Wheel chocks and supports.

Which pads to choose for Chevy Niva?

The choice of pads depends on your budget and preferences. At the moment, at least 6 types of front pads from various manufacturers are offered.

• Finwhale pads /2121-2123/ V221 set price from 500 rub.
• Pads Beginning 2121-3501090 set price from 300 rub.
• ADR pads ADR010611 price from 350 rub.
• Nippon pads ADB0192 set price from 450 RUR
• ABS pads BEST ABS010611 price from 300 rub.
• Lynx BD-4602 pads price from 600 rub.

All of the above brake pads are suitable for Niva 2121, as well as Chevy Niva. They have the same calipers.

Purpose and design of the brake disc

Any driver knows that car braking is carried out due to friction. It is simply impossible to stop the car in any other way, so friction reduces the speed of the car. The main role in braking due to friction is played by the brake disc, which actually stops the moving wheels. The disc can be made of cast iron, carbon fiber or ceramic. Chevrolet Niva is equipped with a cast iron product.

Brake discs on the Chevrolet Niva are installed on all wheels, so there are front and rear discs. Their purpose is the same, only the design is different. The rear disc is predominantly called a drum, as it has the appropriate shape.

The front disk mainly has the form of a flat support, on which the working elements of the system are exposed. These elements heat up during braking, and therefore wear out. Heating indicates a wear process, so sooner or later, in addition to the pads, it is necessary to replace these products.

Malfunctions and their definition

During the operation of the car, all its parts wear out. The brake disc is no exception, although its service life is much higher than the pads. But any small particle, water or dust can significantly reduce its service life.

Naturally, the first sign of a malfunction of these parts is problems with braking. The driver will feel this phenomenon on his own. But the most objective is considered to be a check at a service station, where technicians will conduct a full diagnosis and report the slightest malfunctions.

If you don’t want to “drive” the Chevrolet Niva to a service station, and you want to save money, then you can determine the cause of the malfunction yourself at home. What will you need for this? A faulty brake disc can be determined by the following signs:

1. If, at the moment of braking, unusual phenomena are felt: noises, grinding, jerking, etc.
2. When cracks, chips, gouges, etc. form on the disk.

If such phenomena are noticed, then measures must be taken. Over time, the disc wears out, so its thickness is determined with a caliper, which should not exceed the norm. The difference in thickness of a new and used disk should not exceed 3 mm. If such a phenomenon is appropriate, then there is only one solution - a replacement is necessary.

If the disk has a normal thickness, but chips and cracks are observed on it, then you can try to sharpen it. After turning, the thickness of the product should not be less than 9.5 mm.

Removing and replacing the product

If the malfunctions described above occur, the brake disc will need to be replaced, but before that it must be removed. First of all, you need to prepare a standard set of tools, which include:

• wrenches for “10”, “14”, “17” and “27”. It is best to use a ratchet wrench;
• screwdriver;
• pliers;
• jack;
• hammer.

So, let's start removing the front brake discs of a Chevrolet Niva:

1. Initially, we install the car on a flat surface, release the handbrake, put on shoes, and use a jack to suspend the front part.
2. The nuts are unscrewed and the front wheel is removed.
3. The caliper is removed. The process of removing it is quite delicate, so details of removal can be found in the relevant sections of this site. It is only worth noting that the hoses do not need to be removed, and after unscrewing the caliper, it is necessary to hang it on a wire.

It is forbidden to hang the caliper on the hose, as it may burst, and then it will need to be replaced.

A nut screwed onto a bolt will not allow the thread to be damaged, since direct impacts will fall on its surface.

After the repair or replacement has been made, it is necessary to assemble all the elements in the reverse order of removal. During the assembly process, it is important not to forget to lock the bolts securing the guide pads. Correct pressing of the hub and disk is carried out using the method of screwing the nuts “crosswise”.

Thus, replacing the disc will prevent brake system malfunctions.

What to do if the disk gets hot?

During the operation of a Chevrolet Niva, moments arise when the brake discs heat up. And this is a normal phenomenon, because the physical process of friction is caused by heating of the rubbing parts. Heating the surface of a product is a negative phenomenon that entails many problems: the appearance of cracks and defects, abrasion. What to do if the brake elements get hot? Is there any adequate solution to this problem?

From the factory, Chevrolet Niva cars are equipped with cast iron brake elements that have a hollow surface. Currently, many manufacturers produce so-called ventilated products. What it is? Ventilated discs are products that have special holes or notches. With their help, thermal energy is removed, thereby preventing the element from overheating to a critical temperature. The notches reduce friction to a minimum, so the brake elements do not heat up as intensely. The reliability of such products has been proven in practice, so a solution to the problem if the brake elements get hot has been found.

How to install ventilated elements? You won't be able to simply buy new ventilated discs, because some minor modifications will be required. For this you will need:

• Replace wheel rims from R15 to R16.
• Buy ventilated discs, which heat up much less than the base ones during braking. You will also need a new set of pads.
• Install a new caliper and mounting bolts.

After this, all these parts are installed. The difference is noticeable immediately, so you will not regret this modification of the brake system. The photo below shows products that have ventilated properties.

Drawing a conclusion, it is worth noting that although sometimes brake discs have a long service life, it is very important to monitor their condition, since the life of the driver and passengers depends on their serviceability. By installing new modern ventilated brake elements, you can forever forget the phenomenon when they heat up and fail.

Guide for removing and installing rear pads on a Chevrolet Niva

Chevrolet Niva is a car from the SUV class. And for an SUV, the condition of most control systems is the key to successfully passing an obstacle. Thus, an important role is played by the braking system and the parking brake, which performs the function of blocking the wheels while stationary. Blocking or braking of the rear wheels of the car is performed by drum brakes. The most important elements of these brakes are the rear pads of the Niva Chevrolet. Actually, this article will tell about them.

Removing the drum

What are pads

The brake pads are arched in the shape of the letter “C” and are installed in the rear wheel drums, where they do their work. The brake pad consists of the following elements: 1. the main part, made of special steel; 2. friction lining applied to the brake pads from the back of the head; 3. fastening elements, which are various holes.

Rear brake pads

Let's briefly consider the principle of operation of the rear pads. So, the brake pads are located in the rear wheel drums, two in each. They are located with the inner side facing each other, and the outer one, with a friction layer, interacts with the wheel drum. The resulting interacting force, which is accompanied by the release of energy, ultimately leads to the car stopping.

When you press the Niva Chevrolet brake pedal, pressure is created in the brake system, which acts on the pistons in the working cylinder. The so-called extrusion of the pads occurs; the friction part interacts with the moving wheel drum and leads to its braking. As the pads wear out, the friction layer wears off. The inside of the drum is also erased.

When is pad replacement necessary?

Before replacing the rear pads, an inspection must be carried out. A malfunctioning handbrake does not mean that the brake pads are urgently needed. They change in the following cases:

1. If the thickness of the friction layer is less than the permissible value, that is, less than 1.5 mm. 2. There is oil or other liquids on the lining. 3. There are cracks, gouges or chips on the layer. 4. The connection between the gasket and the base is weak.

Removing the brake drum

Only disassembly and detection of one of the above damages indicates the need to replace the pads.

Replacement of brake system elements

Replacing elements requires the availability of basic tools and careful implementation of repair actions. 1) It is necessary to place the Niva Chevrolet car on a flat surface and set second gear to the gearbox. Bars are placed under the wheels to secure the car in a stationary state. Set the handbrake to its lowest position. 2) Using a jack, lift the rear part and remove the wheel. Next, the drum is removed and a picture of the arrangement of the elements of the rear brake system is observed. Now you can remove the brake pads in two ways, let's look at both:

Disconnecting the spring

First extraction method: 1. One of the ends of the upper spring is pryed up with a screwdriver and removed. 2. The spacer bar installed below the spring is removed. 3. The support post, located in the middle, is held by hand on the back side of the shield and, using pliers, the outer post of the front block is rotated until the slots coincide with the protrusions. 4. The tension spring with both cups is removed and the stand located on the reverse side is removed. 5. The upper part is slightly retracted and the lower spring is removed. 6. Next, retracting the rear part, the drive lever is pulled out and freed from the tension cable. Second extraction method: 1. The support posts are removed from both edges. 2. The rear block is pryed up with a screwdriver and removed, first removing the spacer plate. 3. The upper fastenings are removed from the working cylinder. 4. The lower spring and both elements are removed along with the spacer bar and the spring. 5. The tip of the cable is removed from the lever, and the brake pads, complete with bar and spring, are removed. 6. Now holding one element, the spring and spacer are removed.

Selection of brake system components

Remove the corresponding front wheel. Slowly rotate the brake disc so that it can be seen from both sides. If necessary, remove the brake pads. Measure the thickness of the brake disc using a micrometer. Brake disc wear from pads must be within acceptable limits. If wear exceeds the permissible limit or there are cracks on the disc, the disc must be replaced. If necessary, clean the perimeter of the disc from rust and brake dust.

Use a dial indicator to check the runout of the brake disc. Fix the dial indicator in any convenient place and, turning the disk, determine its runout at several points from its center. If the disc runout exceeds the permissible limits, the disc must be replaced. However, the cause of disk runout may be a failure of the wheel bearing.

Check the brake disc for cracks, especially around the wheel bolt holes. On models with Bendix calipers, remove the brake pads. On models with Girling calipers, unscrew the two bolts securing the caliper to the hub.

Remove the caliper and use a soft wire to tie it to the front strut. Do not deform or stretch the brake hose. Using chalk or paint, mark the position of the brake disc relative to the hub.

Unscrew the screws securing the brake disc to the hub and remove the disc. Installation is carried out in the reverse order of removal, taking into account the following points. Check that the working surfaces of the brake disc and hub are clean and not deformed. Align the previously made marks, install the brake disc and secure with screws, tightening them to the required torque.

If a new brake disc is installed, use a solvent to remove any protective grease from it.

Removal and installation

Removal

. Raise the front of the car, place it on stands and remove the wheel.

Remove the hose guide brackets. Unscrew the bypass bolts, disconnect hoses 10 from the cylinder block (see Fig. 6-11), while preventing dirt from getting into the cylinder cavities. Plug the inlets of the cylinder block and hoses.

Having straightened the edges of the front brake protective casing, unscrew the bolts securing the brake to the steering knuckle (Fig. 6-12) and remove the brake assembly.

Installation

Replacing the front brake disc of a Chevrolet Niva

If the disc cannot be removed because the pins cannot be knocked out, then you have to pick up a grinder and cut off the excess parts. Below watch the video in which the author was unable to remove a disk using a homemade puller and used an angle grinder to remove the disk that was stuck on the hub.

Sometimes this is the only option for the Chevrolet Niva - brute male power. Niva's wheels are heating up - what to do in this case? Applying light blows with a hammer to the edge of the hub, we knock it out and separate it from the video of removing a Chevrolet Niva brake disc with a disc. At this point, the repair work on removing and replacing the brake disc on a Niva Chevrolet car has been completed.

Make the necessary repairs, then install in the reverse order.

Currently, many manufacturers produce so-called ventilated products. What it is? Ventilated discs are products that have special holes or notches.

With their help, thermal energy is removed, thereby preventing the element from overheating to a critical temperature. The notches reduce friction to a minimum, so the brake elements do not heat up as intensely.

Replacing a brake disc on a Niva Chevrolet

How to install ventilated elements? You won't be able to simply buy new ventilated discs, because some minor modifications will be required.

To do this you will need: Replace the rims from R15 to R. There was no runout of the new rims, everything was spinning smoothly. Additionally, I pumped the brakes and checked the calipers for brake fluid leaks, since the pistons changed their position, but I did not change the cuffs.

But everything was fine there too. The appearance of extraneous sounds video of removing a brake disc on a Chevrolet Niva while braking: The car may pull to the side.

A visual inspection may reveal the appearance of cracks, chips and other defects. To understand how bad the level of wear is, you may need a caliper.

What to do if the disk gets hot?

Since the mechanism takes on the friction of the pads, slight heating is inevitable . However, in some cases the mechanism heats up to excessive levels. In such a situation, the question arises: is this a normal option or is repair necessary?

Typically, the brakes become very hot when the pedal is pressed frequently , which occurs during an aggressive driving style. For example, brakes in sports cars get very hot. High operating temperatures not only increase wear, but also affect braking. The braking distance becomes longer, and this can lead to an accident.

There may be other reasons for strong heating . The temperature may increase after recently replacing the pads, in which case everything will return to normal after a while. The pads may be of poor quality, or they may simply be stuck. Also, strong heating may indicate severe wear.

Replacing Niva front brake discs

Experienced car mechanics remove the entire disc along with the fist and squeeze out the disc using a press. If there is no puller, people often start hammering on the disc from the back side - sometimes this helps, but we do not recommend doing this.

The edges of the brake disc simply break off from impacts. If the disc cannot be removed because the pins cannot be knocked out, then you have to pick up a grinder and cut off the excess parts. Below watch the video in which the author was unable to remove the disk using a homemade puller and used an angle grinder to remove the disk that was stuck on the hub.

Sometimes this is the only option for the Chevrolet Niva - brute male power. Niva's wheels are heating up - what to do in this case? It happens that during operation the car wheels begin to heat up.

This may indicate either their poor quality or breakdown.

Finally

We discussed how you can install an HTD on a Niva. Such a solution will significantly improve the performance of the braking system, making it safer and more efficient. At the same time, to carry out this work you need to have a good understanding of the operating features of the vehicle. If you do not have the proper knowledge and skills, you should turn to professionals, because if you damage your brakes, you may find yourself in an unexpected situation on the road. Which is fraught with serious consequences.
