Lada Priora: checking and replacing the brake pads of the front wheels

Car : Lada Priora. Asks : Ivan Chuzhakov. The essence of the question : verified part numbers for the front pads on a Priora with ABS?

The front pads squeaked, their mileage is unknown. The previous owner said that he changed it for maintenance, which means about 30,000 km. Not enough for me, if the owner doesn’t lie.

Therefore, please tell me the verified part numbers of the front brake pads. I have a 2010 Priora Lux, with ABS. I understand that special pads are needed there?

Through the caliper window we estimate the thickness of the brake pads.

We replace the brake pads of both front wheels if the thickness of the friction lining has reached the maximum permissible value - 1.5 mm. Rotating the brake disc, inspect its working surfaces on both sides. There should be no cracks or deep grooves on the working surfaces of the disc.

Peculiarities

The first step is to remove the rear wheel and fix the car. If the vehicle is equipped with an anti-lock braking system, then the rear brakes have design features, and this must be taken into account. On a car with ABS, disconnect the wheel speed sensor from the brake shield. This is done so as not to damage the sensor or wiring. Under the drum there is a master disk for the ABS sensor. How to dismantle it? Remove the sensor using the E8 head.

Difficulties in selecting parts

Before you begin replacement, you must select a suitable set of pads. There are many options for the Lada Priora on the market. Conventionally, they can be divided into two categories - parts equipped with ABS and those without this system. It is not difficult to understand what type your Lada Priora is - the diagram of cars with an anti-lock braking system includes an ABS sensor and a wire connected to it.

The basic principles of selection are common to the two categories. The product must be well packaged, have protective holograms and quality certificates. When purchasing a whole set with release springs, it is advisable to check them. We often came across sets from China where the spring brackets were turned in the wrong direction.

There is no need to look for how much the cheapest kit for a VAZ will cost. It is better to give preference to original parts or famous analogues. Even at a higher cost, the pads will provide excellent service life and excellent braking dynamics.

Selection for cars with ABS

Below is a list of pad sets with the best price-quality ratio.

Selection for cars without ABS

If your Lada Priora is not equipped with an anti-lock braking system, then you should purchase special pads. The most popular sets are the following.

Attention! The brake pads of the front wheels must be replaced as a set - all four pads. Replacing the pads of only one brake mechanism can lead to the car pulling to the side when braking.

If the fluid level in the brake hydraulic reservoir is at the MAX mark, then before installing new pads, use a syringe or a rubber bulb to pump out some of the liquid from the reservoir so that when the piston is recessed into the wheel cylinder of the brake mechanism, liquid does not flow out from under the reservoir cap.

After removing the front wheel, we securely fix the car on a factory-made support stand.

Brake pads Lada Priora (2170) 1 Sedan 1.6 98 hp

Brake pads consist of a friction compound cast and glued or riveted onto a metal backing plate. Friction material wears out naturally and the pads must be replaced periodically. There are many formulas for producing friction materials such as organic, semi-metallic or ceramic with unique characteristics. When it comes to brake pads, there is always a choice between standard and premium ones.

Standard brake pads Lada Priora (2170) 1 Sedan 1.6 98 hp. Best suited for normal driving conditions such as city driving, daily commuting or highway driving. Generally, stock brake pads are the most commonly used OE brake pads, are the least toxic to the earth, and are the softest for all types of braking systems. These pads provide low noise levels during operation, as well as extremely low wear on the brake discs. Advantages of standard brake pads:

• simple and reliable braking
• smoother, quieter braking
• uniform wear throughout the entire service life
• good quality and low price

Premium brake pads provide superior braking performance and reliability for cars and trucks. All premium brakes are engineered to extend life and maintain high levels of friction at all operating temperatures and often feature OE type gas sipes and chamfers to optimize braking performance in emergency situations or on the track.

It is customary to classify brake pads into three types:

• Organic brake pads are made from organic fiber. Organic pads generally do not wear down the brake rotor and provide quiet operation, but they wear out faster than other types and do not perform well in high temperatures.
• Semi-metallic brake pads - contain a mixture of steel, iron, copper and other inorganic fibers. They provide high temperature performance and wear resistance, but cause increased noise, brake disc wear and brake dust.
• Ceramic brake pads are organic, but contain ceramic and copper fibers that allow them to perform well at high temperatures, with less wear, virtually silently and without causing disc wear or brake dust.

The choice between these characteristics is a choice between the efficiency and cost of brake pads Lada (VAZ) Priora (2170) 1 Sedan 1.6 98 hp. . Regardless of your choice, our specialists will help with the selection, check the applicability of the VIN code and recommend a quality manufacturer in any price category.

Attention! Once the caliper has been rotated relative to the shoe guide, do not press the brake pedal as the piston may come out completely from the cylinder.

We clean the pad seats in the caliper and the pad guide from dirt and corrosion.

Before installing new pads, it is necessary to move the piston as much as possible inside the cylinder. This operation can be performed in different ways.

Adjusting the handbrake of Lada Priora with your own hands

We turn the adjusting nut clockwise, thereby tightening the handbrake cables. The full stroke of the handbrake lever should be from 2 to 4 teeth (clicks). When the handbrake is adjusted correctly, with the handbrake lever lowered, the wheels should rotate freely. After adjustment, use the locknut to fix the adjusting nut.

This completes the replacement of the rear pads on the Priora and the adjustment of the handbrake. If you have any questions, ask them in the comments.

After replacing the pads, press the brake pedal several times to set the gaps between the pads and discs. We check the fluid level in the tank and, if necessary, bring it up to normal.

During operation, the surface of the brake disc becomes uneven, as a result of which the contact area of ​​the new, not yet worn-in pads with the disc decreases. Therefore, during the first 100 km after replacing the pads, until the new pads have broken in, be careful, as the car’s braking distance may increase. In this case, the pads may become hotter than usual, up to the appearance of slight smoke and odor, especially in hot weather.

Lada Priora: checking and replacing the brake pads of the front wheels

Pads for Priora with ABS

Article number - 21100-3501800-82 . The original brake pads used in the Lada Priora car are not suitable for all motorists.

Despite the reasonable cost, the manufacturer itself does not recommend using the production version for aggressive driving. The fact is that prolonged braking can cause overheating of the linings, which subsequently leads to boiling of the brake fluid and module failure.

Therefore, many motorists are looking at high-quality analogues.

Now brake pads for Priora are produced by a number of manufacturers. The most popular products are from companies such as Fedoro , Ate , TRW , BM , Pilenga . Front brake pads from these manufacturers are not only not inferior to the original, but even superior to it. Let's look at them in more detail:

1. Fedoro. Brake pads with markings are ideal for Lada Priora FDB527. Depending on the color of the packaging, they are divided into “green” and “red”. The latter are called Fedoro Fedoro Premier and are considered the best choice for VAZ cars, since they have increased rigidity, and the manufacturer itself positions them as “class” pads. comfort" Green ones (Fedoro Target) will be a little softer, which is why they brake worse. However, such pads are more gentle on the brake disc.

   Fedoro Target (green).

2. ATE. At first, such pads may make squeaks and other extraneous sounds. However, as they break in, they break in and work perfectly in tandem with standard brake discs. Ate front disc pads for Lada Priora have a catalog number 13046029652.

   Now our Priora is equipped with ATE. They brake well. The photo shows about 25,000 km.

3. TRW . Another high-quality front brake pads for the Lada Priora. The company produces a version with and without ABS. The difference is that products with an anti-lock braking system are equipped with a hole for the sensor. The pads have good adhesion to the discs and no overheating. This is a reliable option. Marking of front brake pads TRW – GDB469M .
4. Pilenga . Korean manufacturer whose products are low cost. In this regard, Pilenga brake pads are in high demand among domestic car enthusiasts. Despite the fact that these products will be better than the original ones, they are still inferior in characteristics to the models described above. The catalog number of the front pads for Priora is FDP2005 .
5. B.M. _ Chinese inexpensive pads that have good technical characteristics. Due to their low cost, they are often installed instead of standard Priora pads. The quality is approximately the same as Pilenga products.
6. Bosch . We won’t write much here, this is a company that is the standard of quality. But there are a lot of fakes on the market, which even very popular spare parts sales networks suffer from. 0986491700 - by the way, on our previous viburnum, we had Bosch. They have proven themselves very well!

Pads without ABS

Yes, brake pads with and without ABS are different.

But they differ only in the presence of a wear sensor. Which doesn't always work correctly. Therefore, you can install pads from VAZ-2108, VAZ-2110. By the way, most Priors come without a wear sensor.

Vehicle preparation and tools

Before you start replacing the rear pads with your own hands, you need to prepare a tool. We will need:

• a set of standard keys;
• minus and Phillips screwdriver;
• pliers;
• wooden mallet or rubber mallet;
• metal brush;
• Additionally, you can get graphite lubricant, VD-40 fluid and a special hook for removing the tension springs.

Adjusting the brakes

After replacing parts, it is worth adjusting the handbrake using the adjusting screw, and also bleeding the brakes.
Additionally, inspect the integrity of the mechanism parts, oil seals and seals. If necessary, replace. Before driving on public roads, check the functionality of the system and remember that the car will slow down worse at first, because the pads need to get used to the drum.
