Life hack: brake discs of a Priora car - malfunctions, removal and installation

The brake discs on a Priora car, like any other, are an important part of the front suspension, which is the first to begin braking. There are two options for wheels on Priora - regular factory ones and ventilated ones.

The design of the Lada Priora brake system is such that “drums” are installed at the rear, and calipers at the front. This has been going on since 2101. However, it is possible to modify the rear brakes - that is, install brake discs with calipers and backwards, instead of drums. Spare parts for the brake system on Priora must be purchased and installed by the owner on time - the safety of travel depends on their “freshness”. The ventilated front disc has an advantage over a regular one; it is lighter and has plenty of holes, which means it cools down faster! The Priora, of course, brakes well in stock, but until you have driven a Ford or Kia, disc brakes are better there. The price of ventilated brake discs for a Lada Priora car starts from 4,000 thousand rubles and above, standard ones are cheaper than 1,100. In three years, my factory production has reached 2 millimeters.

Remember that the price of these spare parts is incomparable to the damage that you may incur if the braking time increases due to wear and tear of the components. Replacement must be done on time. On the Priora, front brake discs are installed in all trim levels, but the rear ones are a subject of tuning for daring car owners.

Signs

What symptoms can be used to determine that the brake discs on a Priora need to be replaced? The main sign of wear and tear is the behavior of the car. If the working surface of the brake disc is deformed or worn, it will “cling” when you press the pedal. Also, when the pads are activated, a strong grinding noise is possible (not to be confused with the squeaking of the friction material itself). If there is a crack, braking is accompanied by beating against the steering wheel. The friction lining touches the slightest shoulders and other irregularities on the working surface of the disk.

Advantages of disc brake

Despite the fact that the domestic manufacturer does not install such mechanisms on its products, they are becoming increasingly common among car enthusiasts. The whole secret lies in the advantages of this choice, in particular:

• significant reduction in braking distance;
• quick brake response to pedal pressure;
• basic care;
• uniform operation of the system;
• no need to constantly tighten the handbrake cable;
• They are not afraid of cold weather, because they simply do not freeze.

In addition, such brakes have an attractive appearance. Next, we’ll talk about how to correctly install the mechanism on the Lada Priora.

About the groove

Is it wise to repair your brakes? "Priora" is a relatively inexpensive car, but the cost of turning old discs is up to 75 percent of the cost of new elements. In addition, this restoration method is ineffective for serious deformations in the form of cracks and large wear (the thickness of the working surface is less than 6 millimeters). Reviews from motorists say that a smart decision would be to buy a new set of wheels. When old ones clear up, there is a high probability of repeated symptoms. After a couple of thousand kilometers, such a car begins to vibrate again, and the brakes become less informative. Moreover, it makes no difference whether the groove was performed on the removed element or directly on the hub. If you want to be sure of your safety, install new brake discs on your Priora. Which ones are better to choose - we will consider further.

Installation of brake pads and discs from a foreign car

Instead of original VAZ brake pads and brake discs, install consumables from a foreign car, for example:

No modifications or design changes to the brake system are required. The maximum that may be required:

What kind of feedback can you leave about such a simple brake tuning? Is it worth switching from R13 to R14 brakes and abandoning original spare parts in favor of imported ones? Let us remind you that other useful tips for improving Lada cars can be found in the “Tuning” category. For example, you can significantly reduce noise in the cabin by installing additional door seals.

Non-ventilated

These are the simplest brake discs that are installed on the basic configurations of Lada Priora cars. It is believed that this type has an outdated design and is practically not used on modern machines. Foreign manufacturers installed non-ventilated discs back in the 90s of the last century. Starting from the “zeros”, even the budget class was equipped with ventilated elements.

Original or analogue?

This is what AvtoVAZ writes about the original LADA brake discs.

Original brake discs meet high LADA standards and guarantee quality, for this:

• Each batch of brake discs undergoes random inspection and checks of the metal structure using special equipment, excluding porosity and other casting defects
• The disc is made from high-quality cast iron, which guarantees no warping effect during sudden braking or overheating.
• Brake discs undergo high-precision processing to ensure the absence of runout and imbalance
• All original LADA spare parts undergo numerous tests confirming the reliability and quality of each part.

Perforated

These elements have a more complex structure. The design combines two thin metal disks 5 millimeters thick. Between them there are so-called channels through which air flows. Thanks to such ventilation, the operating temperature of the disk is reduced by one and a half to two times. And as we know, when braking, a friction force arises, which is converted into thermal energy. Disks require high-quality heat dissipation.

Some facts

Initially, perforation appeared on sports cars. The working part of the brake disc was drilled using special equipment. The result was through holes and grooves through which air circulated from the center outward. A few years later, perforation began to be used on ordinary civilian cars. But, despite such popularity, the price of such discs has not decreased at all, since the production technology has remained the same. In addition, high precision work is required. At the slightest discrepancy with the standard, such a disc is rejected and does not go on sale.

Manufacturers

There are several popular manufacturers of brake discs on the market for various car models:

• TRW is a well-known manufacturer of brake discs for various brands and models of cars. They are considered a fairly good manufacturer, with decent declared characteristics. In terms of price/quality ratio, it is one of the best on the market. According to their characteristics and dimensions, they are well suited to domestic cars and budget foreign cars (Lada Kalina, Priora, Granta, Hyundai Accent). The average cost of a set is about 4,000 rubles. The manufacturer’s line includes both conventional and products with perforation and ventilation;

• Bosch – the most famous German manufacturer of automotive components. Its products are deservedly considered one of the best on the market, due to the use of a strict quality control system. These are perfect for models - Chevrolet Lacetti, Mitsubishi Lancer and other C class models. In terms of their characteristics, they are in no way inferior to famous and sporty models. The range includes all types of brake discs. The average cost is about 7,000 rubles. The main problem when choosing and purchasing such discs is the large number of counterfeit products on the market. On the official website of the manufacturer you can see information about original products and completely protect yourself;

• Brembo – this manufacturer stands out from the general range of competitors. The products are considered premium products and are installed on expensive sports car models. According to its characteristics, it will give a head start to any competitor. They are distinguished by excellent adhesion properties, high resistance to overheating when working in extreme conditions and excellent endurance. The cost of the kit directly depends on the model. The starting price is about 35,000 rubles. According to the results of numerous ratings, they invariably occupy leading positions;

• Otto Zimmermann – a well-known German manufacturer of high-quality brake discs. Known for its products for several decades. The main distinguishing feature of the products is consistently high quality and excellent wear resistance during long-term use.

The product line is diverse and includes various modifications for car models. The cost of the kit depends on the modification and model of the machine. The average price is about 8,000 rubles.

About braking efficiency

When the pads come into contact with the disc, gases are formed (boundary layer), which prevent good adhesion of the friction material to the working surface. Thanks to the presence of grooves, they are easily removed. In the case of non-ventilated discs, these gases continue to slide across the metal, preventing the pads from working properly. As a result, the braking distance increases. As we have already said, preformation allows you to reduce its length by 15 percent. 100% adhesion is ensured between the metal of the disc and the working surface of the pad. In some cases, in addition to holes, grooves are used. They have a depth of about two millimeters and are directed towards the rotation of the disk. The grooves clean the working surface well of accumulated dirt, sand and other deposits that have formed there when the car was driven. In the absence of perforation, this dust settles deeply on the surface of the disc. This causes a squeaking sound when braking. The driver cannot understand the cause of the malfunction, especially if the pads have recently been replaced.

How to remove the Priora caliper

You will need: remove the front wheels and prepare a 17mm spanner. Procedure:

1. Unscrew the two bolts securing the shoe guide to the steering knuckle using a 17mm wrench.
2. Remove the pad guide from the disc along with the bracket and pads.
3. Make sure that the brake hose is not stretched; to do this, tie the caliper to the suspension spring.

If you have to unscrew the working cylinder from the tip of the brake hose, then you should close the hole in the hose in any way so that the brake fluid does not leak out.

Installing the Priora caliper is done in the reverse order. Check that the brake hose is not kinked. After installation, do not forget to check the brake fluid level in the reservoir and remove air from the brake system.

What to choose in the end?

What kind of front brake discs should I put on the Priora? Reviews from motorists agree on one thing - it all depends on the driving style. If you prefer an aggressive style, with sharp acceleration and braking, the presence of perforations and grooves is simply necessary for you. But if the car is used for leisurely driving, there is reason to think about installing non-ventilated discs. A compromise option is to purchase ventilated discs without perforation, but with grooves.

Many cars have front brakes with disc brakes and rear brakes with drum brakes. But there are exceptions to this rule, and not only in auto racing, where all 4 wheels are equipped with disc brakes for the sake of reliability. Manufacturers in other countries equip only budget modifications of cars with drum systems; most of them have all disc brakes. But is it possible to equip a domestic car, for example, a Priora, with rear disc brakes and which ones are better?

Original and fake

Now there are a huge number of fakes on the market, which are sold under the famous brands Zimmerman, ATE, Bosch and Brembo. It is quite easy to distinguish an original from a copy. First of all, this is the thickness of the disk. If it is less than one centimeter, most likely you have a copy in your hands. Reviews from motorists recommend paying attention to the junction of the two parts of the disk. The internal grooves should connect smoothly to the work surface.

What's next?

First, put the car on the handbrake and put the anti-roll bars back. Next, use a wheel wrench to remove the wheel bolts and jack up the front part. Remove the wheels and unscrew the brake fluid reservoir. Using a vacuum syringe, pump out some of it into a previously prepared container until the level in the tank drops to half. This way we will prevent it from getting on the pads when dismantling them. Next we need a thick minus screwdriver. We install it between the outer brake pad and the caliper and pull back the piston. It is important not to damage it - for this reason, work extremely carefully. Then we take the “13” key in our hands (you can take a horn or ratchet) and unscrew the lower mounting bolt. If there is a locking bracket, turn it with a screwdriver or bend it with a chisel and hammer. Using the “17” key, we tighten the rotary pin.

Replacement steps

The entire replacement process can be divided into several stages:

• Removing wheels;
• Removing the old brake pad;
• Frame disassembly;
• Cleaning the hub and checking it;
• Removing coating from new disks;
• Runout check;
• Installation of new brake system elements.

Now let's talk about this in more detail.

Removing the wheel

In fact, dismantling the wheel for subsequent replacement of the brake elements is not difficult.

But a certain sequence of actions will have to be followed.

1. Place a jack under the car.
2. Lift it up so that it doesn't tip over, but still allows you to easily remove the wheels.
3. Unscrew the wheel fasteners.
4. Remove the hubcaps and the wheels themselves.

As you can see, the procedure is really simple, but it requires attention and accuracy.

Removing the pads

1. Try to move the piston as far as possible from the brake mechanism. But do not exceed the distance beyond that which will allow you to comfortably remove the brake pads.
2. Take out the block.
3. To make the job easier, you can disassemble the brake frame. To do this, unscrew the two bolts securing the block and disconnect the device.

Hub

It must be cleaned, since all accumulated debris, dirt, and rust will negatively affect the effectiveness of the new brakes.

Dirty

For cleaning, alcohol-based solvents and metal brushes are used. If cleaning is not performed, the operation of the brakes will be accompanied by beating - this should absolutely not be allowed.

Be sure to check the hub for runout. Normally it does not exceed 0.1 mm. There is a special tool for checking. If the indicator is within normal limits, then a full assembly is performed.

Working with new disks

Many owners of the “Ten” are interested in which brake discs are best to choose for the VAZ 2110. The question is quite logical.

Choose certified replacements from reputable manufacturers such as Bosch, or stay true to factory parts. These are the two best options in terms of quality and compliance with the car itself.

New

Some take similar discs that partially fit the “ten”, sharpen them, and adjust the design. This is a dubious undertaking, since it requires serious skills in such a matter, additional time and financial costs. At the same time, it is far from a fact that such brakes will work better than those offered by the AvtoVAZ plant.

You've already figured out how to remove the brake element, so it's time to work on a new one. It’s not enough to just buy another brake disc and put it in place. First, it is prepared and a runout check is performed. Let's talk about this in more detail.

1. The coating must be removed from a new disc.
2. This coating serves as a kind of preservative.
3. The layer is removed using any solvent.
4. Clean thoroughly and wipe the part dry after finishing work.
5. Now you can put the disk in a new place and check the runout.
6. The permissible runout is no more than 0.15 millimeters.
7. If the value is exceeded, this can lead to an increase in the sensitivity of the brake pedal, as well as the formation of vibrations during braking.

Adviсe

When replacing a disc, new pads should be installed. This is a required step. Some manufacturers include a pair of new pads when purchasing a disc. Also maintain symmetry. Let's say your disk is cracked and you buy one standard “replacement” one. If you install a new one on only one side, there will be uneven distribution of braking forces and asymmetrical wear. The same goes for the pads. They only change in pairs. Also, when replacing, pay attention to the condition of other parts - caliper boots, guides. If there are any gaps or signs of deformation/wear, replace them. After the brake discs have been successfully installed on the Priora, add fluid to the reservoir and bleed the system. The presence of bubbles in it is unacceptable - braking on such a car becomes ineffective. The liquid simply boils from the compression of air.

Right choice

There are many different manufacturers and types of products on the market. Most of all, simple brake discs are produced that are not perforated or ventilated. Their effectiveness, if it exceeds the indications of factory products, is not by much.

Ventilated brake discs are widely used; they have many advantages over standard ones:

• Ventilated discs have ventilation channels for more efficient cooling of the brake disc and pad. During acceleration and braking, the brake disc is subjected to large overloads even in normal mode (without using emergency braking). With high heating, it gradually deforms, its efficiency decreases and the surface is destroyed.

• Allows the disc and pad to be cooled when overheated, thereby maintaining the integrity of the disc;
• A mediocre positive effect is the preservation of the integrity of the brake pad due to the efficiency of the cooling system. This allows you to equalize the wear of both elements, maintaining the efficiency of the entire brake system in optimal condition;
• They are often made of stronger steel, as they have a slightly different architecture due to the presence of ventilation channels.

About the resource

The replacement period for this element directly depends on your driving style. The more often you accelerate and brake, the lower the resource of the node. Factory brake discs installed on Priora can withstand up to two hundred thousand kilometers. But with aggressive driving, this period can be less than one hundred thousand. If possible, brake in gear and switch to neutral in advance before a red traffic light. Use more “rolling” - this will not only preserve the discs and pads (the latter are changed every 25 thousand kilometers), but will also increase the service life of the gearbox. Fuel savings are also significant.

So, we found out how to choose the right brake pads and install them on a Lada Priora car with our own hands.

Types of brake discs. The latest VAZ cars are equipped with ventilated discs; in addition to them, there are also discs with gas outlets, with perforations/grooves (splines) and collapsible ones. Standard ventilated discs perform their duties well during everyday use of the car. The remaining discs (with perforations, gas outlets, etc.) are more suitable for more severe brake operating conditions.

The catalog number of brake discs for Priora/Kalina/Granta is the same: 21100-3501070 or 21120-3501070.

The approximate price of brake discs (set) is 1500 rubles. Costs may vary significantly depending on regions.

To buy good quality brake discs, you should contact trusted stores, rely on reviews, or order brake discs online, directly from the manufacturer. There is a large percentage of fakes on the market.

Resource of brake discs . Brake discs are replaced as they wear out, when the thickness of one of the discs becomes less than the minimum allowable 17.8 mm. Discs should be replaced as a set!

By the way, when choosing, you can rely on reviews of brake discs from VAZ 2110 owners, because the catalog number is the same. What brake discs do you recommend?

Even at the dawn of the automotive industry, much attention was paid to the braking system of the car. Many types of brakes have been proposed. Until relatively recently, the drum system was considered a fairly reliable system.

But, with the advent of powerful engines and high speeds in our lives, they were replaced by disc brakes. This braking mechanism is much more effective, although the brake pads have a much smaller area. Due to the uniform fit of the pads to the flat disc, the greatest effect is achieved. Unlike drum brakes, in which the pads are pressed unevenly against the walls of the drum.

Disc brakes are much better at cooling. They are not filled with dirt, dust and other undesirable components that impair braking. Replacing pads on such brakes is much easier than on drum brakes. The entire system is much more compact, lighter and much cheaper than its predecessor.

The calipers can be left as old, the boots were originally designed for R14 brakes, the movable caliper remains the same.

Types of brake discs installed on Lada Priora and how they differ

The simplest is a regular disk that does not have any additional functions. Such elements are cast entirely from metal and weigh more than other types. They cool worse under load.

The next type is ventilated. They are hollow inside and in this cavity between the working surfaces there are partitions for ventilation. During rotation, air passes between the working surfaces through the partitions and cools them.

Another variety is ventilated, perforated discs with special dust removal recesses and an anti-corrosion coating. This type is almost not subject to corrosion. Due to special cutting, it removes dirt particles from reaching the working surface of the brake pads, reducing their wear.

Also, on cars with an ABS system, another type is installed, which has a special device. In the form of an additional ring with teeth to activate the ABS system.

Pros and cons of ceramic brakes

Let's start with the advantages of ceramic brakes, some of which have already been listed in the previous paragraph:

1. They reduce unsprung weight and load on the suspension due to the fact that the ceramic disc is lighter than the metal one.
2. During friction, virtually no dust is released.
3. They increase the coefficient of friction and braking efficiency when heated to high temperatures.
4. The long service life of ceramic discs is due to the fact that they do not contain an iron alloy.

Ceramic brake pads
Let's move on to the disadvantages of ceramic brakes:

1. High price compared to conventional brakes.
2. Requires warming up before use.
3. During operation, they may produce a squeaking noise, which is eliminated by adding metal impurities to the disc composition.
