Brake discs are an element fixed to the car hub and serve to reduce speed when in contact with the pads due to increasing friction force. The part can be made of cast iron or ceramics: the first type is cheaper, the second is more expensive, but has less weight.
For the Russian car VAZ 2112, mainly ventilated models are produced, which have an effective cooling system and are considered more reliable and durable. The cost of spare parts depends on their type, country of production, type of sale (pieces or sets).
Original
Factory wheels are produced by the Autoreal plant, they have article number 2112350107002 and are sold both individually and in sets. The cost of one part is 850-1000 rubles, depending on the store and city. In addition, in the assortment you can find disks with code 21123501070, they are produced by the same company, the price of such a set varies between 2.2-2.5 thousand.
The products are of good quality and can be found both in regular spare parts stores and online catalogues. Many car owners argue that it is better to purchase parts in a simple store, where you can personally check them for quality.
Disadvantages of drum mechanisms
Drum brakes
Despite the fact that drum brakes are correctly designed, mounted and adjusted at the factory, which is why intervention is not required, they have certain disadvantages:
- This is an outdated solution that is practically never found on new cars from leading European manufacturers;
- When compared with disk mechanisms, drums are significantly inferior in efficiency;
- There is no cooling or ventilation on the drums, which leads to overheating under heavy loads on the car;
- The drums have a closed space, so it is not possible to remove dirt and wear products in the form of black dust, leaks of fuel oil and trapped moisture naturally. This is done by cleaning.

Wheel alignment
After replacing wheel rims, the dimensions and bolt patterns of which differ from those provided for by the design of the VAZ 2110, it is necessary to make all the necessary adjustments in order to ensure reliable protection of the entire chassis, as well as tires and arches.
Correct alignment angles are required for each front wheel. There are three parameters that require correct installation: wheel toe, caster angles of the steering axles, and camber angles of each wheel.
Wheel installation options
The rules by which the parameters of the front wheel are set are as follows:
- You won't go far if everything hangs out the way it wants, and the car is pulled to the side when it should be going straight. To ensure the stability of each front wheel, they are installed strictly at the required angles to the body and suspension elements. This is called the longitudinal inclination angles of the turning axis. Installation dimensions are indicated in the instruction manual;
- Camber is the angle between the plane in which the wheel rotates and the vertical. The camber bolt helps install it (it secures the telescopic strut and steering knuckle). If the camber is installed incorrectly, the car “steals” and the tire tread wears out more on one side;

All about disc brakes
VAZ 2110 installation of rear disc brakes
As you know, on old VAZ 2110 models, drum brakes were installed. But today, given the fact that absolutely all foreign cars, except perhaps budget models, have disc brakes, replacing them is a pressing matter.
Problems that replacement may cause
Rear disc brake set for VAZ 2110
It is noteworthy that after replacing drum brakes with disc brakes, they can cause some problems, of course, if they are not changed according to the instructions. The fact is that disc brakes are not officially installed on VAZ cars, and replacing and installing them is tantamount to tuning, which implies a certain change in the main design. It goes without saying that brakes symbolize the safety of the vehicle. Installing them is not just an ordinary matter; they are not installed just so that they slow down. In the language of a designer, brakes are clearly balanced mechanisms that have been developed by engineers for many years.
Note. Purchasing disc brakes and simply installing them, without following clear rules, is a dangerous undertaking and not recommended.
It’s interesting, but it is at the service station, where most drivers install, or rather replace, rear drum brakes with disc brakes that they do not monitor their correct adjustment. Of course, this does not apply to all service stations, but a certain part of them do not burden themselves with concerns about the safety of the driver who entrusted them with the vehicle. There is only one thing left to do - take the instructions and replace the rear brakes yourself, and at the end check the work as it should be. No one will do better than the driver himself, who will naturally be concerned about his safety. The main problem that can cause concern after replacement is uneven braking and skidding during a sudden stop of the vehicle. In addition, if the installation is not done correctly, the rear brakes may fail at the most inopportune moment or the discs may overheat. In addition, symptoms of improper installation of rear brake discs are squeaking of these parts.
Rear disc brake kit for VAZ 2110
Some experts believe that installing rear brake discs on the VAZ 2110 and other models is not entirely practical. The money allegedly spent on purchasing the kit and installing it may not produce the expected results. But again, if everything is not done correctly. But problems with passing maintenance are already a pressing problem. So far, the installation of rear disc brakes on the VAZ 2110 is considered by law as a design change not confirmed by law enforcement authorities. Therefore, you need to take into account the penalty factor when undergoing a technical inspection. A mandatory component when replacing brakes is the handbrake, which will also need additional care. In particular, you will need to either change the cable parking brake, or make your own hydraulic handbrake, which will allow you to brake at any speed.
Note. But it is worth noting that the hydraulic handbrake is not intended as a parking brake, as it weakens over time.
So:
- A problem with a VAZ 2110 car that has rear brake discs can arise in the event of an accident. Traffic police officers no longer look at who is really to blame, but focus on illegal changes in the design of the vehicle.
- In addition, after installing disc brakes, it will be necessary to adjust the sorcerer. If this is not done, then on a front-wheel drive car the rear wheels will begin to brake more than the front wheels, which will inevitably lead to skidding, especially on slippery or wet roads.
Note. In some cases, an unregulated sorcerer causes not only skidding, but also rapid overheating of the brakes, squeaking, etc.
When the problem cannot be solved using conventional methods, craftsmen recommend grinding off about 25-50% of the pads, thereby reducing the contact area.
How to replace brake discs on a VAZ 2112
Replacement of such spare parts takes place according to the following algorithm:
- First you need to unscrew the wheel mounts and dismantle it, then remove the pads.
- Loosen and remove a couple of bolts securing the block to the cam, and remove the entire brake mechanism. Only the attachment of the hose to the cylinder should be left.
- Attach the caliper to the suspension using a rope or wire connection, making sure that the hose is not pinched.
- Clean the disc and hub from dust, dirt and corrosion. The anthers should be lubricated; if they are torn, replace them. To remove rust stains faster, you can treat them with WD-40 and then wipe them with any cloth.
- Unscrew the disc from the hub, pulling out the guide pins (if they are soured, you need to use a hammer with a rubber tip and knock them off), remove the ring and the part itself.
- Remove the beads on both sides if you plan to replace the restored disk: this can be done using a file.
- Install a new or restored element and perform assembly in the opposite order.
After completing the repair work, you should perform a test drive to make sure that the spare part is installed correctly and that braking is carried out without interference. New discs should respond immediately to pressing the brakes, while acting smoothly, and there should be no extraneous sounds. If necessary, even a person who has little experience in car repairs can replace the disc with his own hands. If the procedure fails, the owner does not have the appropriate experience or does not have time for work, it is better to contact a service center where specialists will take care of the car.
Faceplate and installation features
Before installing disc brakes on a VAZ 2110, you need to remove the old drum brakes. This operation will not take much time and effort, the only thing is that it is advisable to have a puller for the hub and try not to damage the old brake caliper on which the pads and working cylinder are attached. After the old brakes are removed, you can install a new set, according to the instructions
Nothing new is written there, the only thing worth paying attention to is that the guide bolts are lubricated with a special grease, which is not advisable to remove
If the question arises about independently selecting spare parts for installing disc brakes instead of drum brakes, then the only difficulty is the manufacture of the faceplate. We have attached a drawing of the faceplate to the article, and this is what the finished rear beam of a VAZ 2110 with disc brakes looks like.
Despite the effective brakes, be careful on the highway and good luck to everyone!
conclusions
It’s not at all difficult to understand such parameters, the main thing is to remember them and choosing suitable wheels ceases to be a difficulty.
How to choose a wheel rim? Call an assistant, trust the seller, or try to show off your own knowledge? Basic information on the “disco” part is given below.
From the post-war years until the early nineties, owners of domestic cars did not have a headache at all about which wheel to use on their car. There was a Moskvich one with five “holes”, a Zaporozhye one with a huge central hole, a VAZ one with four, and a large (as much as 14-inch) Volgov one. There was also a huge 16-inch Niva disc with five holes, but, oddly enough, it was replaced by some amateurs with the Volgov one. Now the variety of wheel rims is such that sometimes you can’t do without a catalog or the all-knowing Internet.
But let’s consider everything in order: what characteristics can you “play with” a little when choosing and what requirements must be met without fail.
