One of the main problems of the Russian automobile industry is factory assembly. Designers produce a crude product, which is prohibited from being further improved. The same problem affected model 2114. At the factory, the rear wheels are equipped only with drum brakes, because such an assembly reduces the cost on the Russian automobile market. Cars such as the VAZ 2114 can only be produced in specialized workshops.
What is the disadvantage of domestic brake system? The fact is that the 2114 brake was inherited from the “nine”. And therefore they do not have any special improvements: they feel great in dry weather - the braking distance is quite short, but as soon as precipitation appears and the road becomes wet, braking becomes harder and this distance increases significantly. But that's not the whole problem.
Rear disc brakesIt has often happened to many motorists that during frequent and intense braking at speeds above one hundred kilometers, the brakes overheated and the brake pedal “failed.” This unpleasant effect is most often associated with boiling brake fluid, which begins to boil when the discs rub against the pads. The temperature of system parts can reach 600 degrees, which is quite a lot. Sometimes you can notice overheating visually: in the dark, the disks begin to emit a dark red backlight. Well, if in addition you haven’t changed the special fluid for a long time, then the entire brake mechanism will not last long.
Lada Kalina Sport I remind you once again - it is prohibited to make any replacements or changes in the brake system; I am writing this article solely for informational purposes. AvtoVAZ finally began installing brake discs, but it only started with the Lada Kalina Sport, which was launched into mass production only in 2011. The principle of operation of the car's braking system has not changed, so all previous models operate on drum brakes.
Installation details and purchasing spare parts
So, it's time to start installation. The first step is to unscrew the brackets, cylinders and guides. Typically, new discs have a large central hole (CO), and therefore, for correct operation and accurate centering, I would advise cutting a strip from a tin beer can, which must be inserted between the hub and the disc to eliminate play. After this operation, you can put on the disc and screw on a new bracket. Diagnostics of the brake system must be performed without fail.
Rear hub disassembled It is immediately necessary to describe one nuance that drivers encounter with a VAZ 2114 car. It may be that one of the finger holes is significantly smaller than the other. Don’t “do magic with it”; go to a car service center, where in a couple of minutes they will make a hole for you that will be equal to 8.5 millimeters.
If you feel that all is not well with the cylinders, then it is better to replace them. The front one often presents unpleasant surprises, the cause of which is overheating of the discs and pads. A ventilated disc is always wider than the standard one, so you definitely need to buy new protective covers, guide pads and calipers.
Take more time to inspect the products you are about to purchase. This work is for yourself and is done with your own hands, so you need to buy high-quality spare parts, although this causes a slight damage to your wallet.
The brake system does not like saving, there is no need to be clever here - if the parts have served their purpose, you need to replace them immediately. Before starting tuning, the car must be placed on a reliable stand, or use a lift.

Easy step-by-step instructions for installing rear disc brakes
Step 1
We loosen the tension of the cables and bring the rear pads together, then use a 12mm wrench to unscrew the guide pins. Use a metal brush to clean the seat and carefully knock down the brake drum. I recommend using a rubber mallet to avoid damaging anything. Truly super tuning of a VAZ 2114 car requires patience and strength. Using a screwdriver, pry up the spring that tightens the pads and remove it. We pull out the spacer bar and take out the upper tension spring. After this, remove the brake pad, first lowering the handbrake lever.

Step 3
Now you can straighten the corners of the beam before placing the hub combined with the faceplate on the beam. This must be done so that the corners do not interfere with the caliper. Personally, I flattened them with a hammer. This work can also be done using a grinder. You should not install a grinder under the left hub bolt, otherwise you will have to work with the grinder again and file the head of the bolt. The brake caliper bracket may rest against it.
Rear disc brake assembly Step 4
Well, now the most important thing. We install the bracket on the faceplate and put the brake disc on the hub. Place spacers at the connection points. This must be done at connection points. It happens that the size of the washers may differ, then you need to buy them for a specific car, in our case it is tuning a 14 model car. We tighten the faceplates and the connection of the brackets (I recommend doing this with a force of 3-4 N.M). We screw the hose to the caliper, install the pads, and you can close the tube sealing line. Now we seal the brake line. We check the line for leaks by pumping up the pressure with the pedal. If everything works as it should, then you can begin installing the HCD on the other side.
Most accidents occur due to loss of control over the vehicle, especially when braking the VAZ 2109. Tuning the brake system is necessary when increasing engine power, as well as when driving at high speeds.
It is worth noting that the modernization of this particular system is considered the most dangerous and prohibited procedure. On a VAZ 2109, to tune the brake system, you will need to replace standard parts.
Replacing pads and discs
First of all, they begin to consider the option of disks. In almost all cases, preference is given to ventilated discs with special cuts.
The pads most often use reinforced imported ones. It would also be a good idea to install a more powerful vacuum booster.
The superiority of disc brakes lies in the following facts:
- disc brakes are relatively stable as temperatures rise; in the case of drum brakes, their effectiveness decreases;
- since the disks are cooled better, their temperature resistance is much higher;
- Due to the high braking efficiency, the braking distance can be reduced;
- small size and weight;
- better brake sensitivity;
- response time is reduced;
- it is easier to change worn pads, which cannot be said about drum brakes, where you need to spend time and effort on adjusting them;
- approximately 70 percent of the car’s kinetic energy is absorbed by the front brakes, rear brakes help reduce the load on the front discs;
- Temperature changes do not in any way affect the quality of fit of the braking surfaces.
For more than 20 years, the VAZ 2109, created on the basis of the 2108 model, has been considered one of the most popular cars on the domestic market. But despite this, every car owner wants to make their own changes.
For some, it is important to upgrade the headlights or perform body tuning, while others want to change the interior appearance of the cabin. Some drivers consider such measures to be secondary; they improve engines, suspensions and, of course, the brake system.
It is precisely this system that needs to be given more attention.
Note. The most simple option Upgrading the brake system of a VAZ 2109 is considered to be the replacement of “original” brake discs with discs from a VAZ 2110 or VAZ 2112.
What are the main differences between the new disks?
So:
- Such discs are characterized by a ventilated design, thus the heat generated during braking is removed much more efficiently.
- VAZ 2110 cars have a larger diameter, they cool much faster and brake vehicles better.
The effectiveness of ventilated discs can be assessed when braking at elevated speeds. A simple disc heats up significantly, causing the brake fluid to “boil” and the brake pedal to “sag.”
Note!
It should be taken into account that the rims of the 12th model are suitable only if the car uses 14-inch wheel rims. Classic 13-inch ones simply won’t fit on wheels brake machines VAZ 2112.
Before performing such independent work, you need to determine what size disks are installed on the machine. For example, if these are 13-inch products, it is better to give preference to brake parts from the VAZ 2110 model; in the case of 14-inch ones, it is advisable to install brake discs of the 2112 model.
Note! Experts say that the braking characteristics are much more noticeable during installation if you install brake discs on a VAZ 2112 car, since they are larger in size than parts from a VAZ 2110 car.
To modernize the brake system of a VAZ 2109, you need to acquire the following parts:
- two “tens” brake discs;
- two calipers and guide brackets of model 2110 or 2112. Since the brake discs of the “tenth” model are very thick, the caliper with the bracket must be larger accordingly;
- two protective covers.
Note! The composition of the brake fluid directly affects the braking efficiency, as well as the service life of all system elements, which affects the overall safety and reliability of the machine.
It should be noted that if the car has wheel rims with an unconventional offset or a serious body modification has been carried out, there is a possibility that the new “tens” rims will rest against the wheel or even block it. This possibility must be provided for in advance so that the work does not have to be redone.
Based on the information above, it should be said that such brake tuning is not complicated; you can perform the steps yourself, based on simple instructions. The benefits of such an upgrade are very obvious; better cooling and high-quality braking are provided.
To a greater extent, manipulations with the brake system are necessary when carrying out chip tuning, engine and carburetor tuning.
The result of successful work will be an increase in the dynamics and speed of the car.
Today, many car owners who want to improve the condition of their vehicles turn to a service station, but why overpay the technician if, with the help of videos and photos, you can actually do everything yourself? Detailed instructions describing the processes, nuances and tips for modernization will also help.
The price of the necessary elements for replacement is not as high as, for example, the cost of the repair itself. Equipping all four wheels with a disc braking system is now used by all leading car manufacturers. This system is considered the most effective and guarantees high level safety during operation.

Disc brakes
However, the VAZ 2109 has not been produced in the Russian Federation since 2006, and it uses outdated drum brakes. The model is equipped with a disc braking system only on the front pair of wheels, where the load is the heaviest. Replacing drum brakes with disc brakes or the so-called tuning of the rear brake system is of consistently high interest among the owners of these cars.
It should be noted that such an operation is fully justified, leading to savings in fuel and lubricants and increasing safety during vehicle operation.
Brake discs for VAZ 2109
- To carry out such an operation, it is possible to use three types of disc brakes: Their size corresponds to 13 inches and is quite suitable for use. A negative feature is their low efficiency during fast and dynamic movement.
- It is possible to install a brake system removed from VAZ 2111 and VAZ 21102 cars, which has increased aerodynamic properties, appropriate size and sufficiently high performance characteristics.
- The most justified, in the opinion of the majority of owners of VAZ nines, is the installation of wheels mass-produced by the Russian industry, which are used for cars with a 16-valve engine of the VAZ 2112 and VAZ 21103 series. They are fully compatible with 14-inch wheels, have a diameter of 257 mm and with long operation and high loads are most effective.
This option may be the most expensive, but it pays for itself quite quickly and is the most profitable from the point of view of traffic safety in a dynamic urban cycle. It should be noted that the main positive differences of the disc brake system are constant external control over the degree of wear brake pads
, ease of replacement, as well as improved braking quality and increased cooling speed of brake discs. Besides appearance
a car with disc brakes is quite consistent with modern ideas about sports sedans.
Stages of tuning the brake system of the VAZ 2109
After correctly selecting the necessary brake discs, every car enthusiast asks the question: “Can I do the installation myself?”
The average cost of such tuning without the involvement of service center employees will be about 5 thousand rubles. The main expenses will go to the purchase of a brake disc, calipers and a set of faceplates.
Tuning the brake system of a VAZ 2109 car can be done independently and in a garage. The financial side of the issue also does not seem too burdensome for the family budget of auto-tuning fans.
