Today in this article I will tell you how to install rear disc brakes on our beloved “Nine”. “What's wrong with drum brakes,” you ask? Well, let's take things in order. First, disc brakes are less effective at speeds than disc brakes. Secondly, the distribution of brake fluid pressure is easier, which gives us safer braking. Thirdly, there is no need to suffer and knock out this drum, unscrew the studs that constantly stick, remove the springs when replacing brake pads. And lastly, fourthly, This is the appearance of our car. If you have alloy wheels, then through them the rear wheels will look just perfect, and in combination with the front wheels your nine will be simply of the highest class.
So let's get down to business. What do we need to transform our iron horse:
1. Brake disc. Yes, the same as on the front wheels. The issue price is 350-650 rubles. (depending on your region)
2.Support. Also from the front wheels. And don’t forget to take the pads. The price is 900 rubles.
3. Faceplate is also called a faceplate adapter for attaching the caliper, or rather the transition of the attachment to the rear beam. We don’t have this part on the front wheels, so don’t be alarmed, it won’t be difficult for you to find. Any auto store has it in stock. The asking price is 300-400 rubles.
pros
Let's look at why disc brakes are better than drum brakes:
- Braking becomes more reliable, braking distance is reduced;
- Braking forces are distributed more evenly, given that the VAZ 2110 is a front-wheel drive car;
- There is an effect of faster response after pressing the pedal;
- Unsprung masses are reduced;
- Heat dissipation occurs better, which is especially important when driving on a mountain road or during active acceleration/braking. For this reason, the brake system is cooled better;
- Disk ones are much easier to dismantle and replace;
- There is no need to adjust the handbrake after each repair of the rear brakes, although this will have to be done the first time;
- They do not freeze in winter after washing, like drum ones;
- Rear disc brakes installed on the VAZ 2110 are much more convenient to control and promptly notice pad wear.
This article will help you replace the rear brake pads if they are worn out:
Advantages
As mentioned above, on the VAZ 2110 rear brake discs have advantages over drum brakes. In particular, these are such advantages as:
Note. Improved heat dissipation is a very important factor, especially during active driving. In addition, this is relevant when driving at high speeds and on mountain roads.
- significant improvement in brake cooling;
- ease of installation and dismantling in case of replacement;
- brake discs eliminate the need to tighten the parking brake each time;
- reliability of these brakes;
- disc brakes, unlike drum brakes, do not freeze in winter after washing;
- ease of monitoring brake wear;
- an appearance that makes the car look like a sports car (you definitely can’t say the same about the VAZ 2110 with rear drum brakes).
Minuses
Replacing brakes with disc brakes was not without the famous “fly in the ointment,” although it rather concerns precisely those problems that their installation can cause.
Firstly, our law enforcement agencies consider their installation on a VAZ 2110 as a design change.
What might this entail?
Following:
- Fine when passing a technical inspection;
- You can be simply wrong in a controversial accident if traffic police officers emphasize that you have “wrong” brakes;
- And the insurance company may also consider this a reason for non-payment of insurance.
Secondly, the handbrake will additionally need to be modified - or replaced with a hydraulic handbrake, although the latter weakens over time.
An article containing step-by-step instructions for replacing the handbrake cable can be found here:
Thirdly, it is necessary to refine or carefully adjust the sorcerer so that on the VAZ 2110 the rear wheels do not brake more than the front ones, as this will certainly cause a skid, especially on ice or wet asphalt. To do this, sometimes you even have to grind down the pads by a quarter, or even more.
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

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.

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.
- 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.
Design Features
It is better to purchase rear disc brakes as a complete set. The VAZ 2110 fits 13 or 14 inch brake discs (ventilated or non-ventilated). Try to purchase certified discs so that they do not have to be modified.

You also need a caliper, which comes in three types, so you need to select it to match the disc. The caliper comes with a hose and brake pads. The kit includes a universal clamp suitable for all calipers - a faceplate.
Dismantling
Before installing disc brakes, you need to dismantle the old rear brake mechanisms of the VAZ 2110.
This is done like this:
- Remove the wheel;
- Remove the brake drum;
- Remove the pads;
- Remove the hub from the wheel, having first unscrewed the brake pipe.
You should prepare for the fact that dismantling will not be easy. Not only do the brakes have the unpleasant tendency to stick during operation, but the bolts are also “welded” by corrosion. Therefore, it is advisable to treat the nuts and bolts themselves with a special agent (for example WD 40) so as not to tear off their edges.
It is important to plug the removed pipe with something so that brake fluid does not leak out and air is not sucked into the system. After that, knock down the hub. This works best if you attach a board or lath to the back of the support disk and hit it with a hammer, moving the blows: one from below, the other from above. This will prevent you from causing serious damage to the disk.
Bleeding and adjustment
After any manipulations with the brake system (it doesn’t matter whether you repaired the rear, front or parking), on a VAZ 2110 it is vitally important to bleed the brakes so that an air plug does not form anywhere in them, which can negate the ability to brake at the right moment.
It is convenient to do this together, but you can do it yourself, although this requires some additional equipment. Many people know how to bleed the brakes on a VAZ 2110. The main thing is not to forget to do this diagonally, always starting with the front wheels, and pump the right one first.
After bleeding, you still need to check the braking forces. This requires an outside observer. You accelerate and brake sharply, and he watches as the brakes apply. The front ones should work first, then (with a small gap) the rear ones, and the braking force should be greater for the front ones.
Everyone knows that the rear brakes of the VAZ 2110 are drum brakes . I don’t think it’s worth talking about the fact that these are brakes from the 40s.
