Which APs should be used for replacement?
Now the time has come to change the TD, but the car owner does not have the money to go to a service center or he does not trust those who work in one service station for the entire small town. In this case, the car owner, if he is not too lazy, can replace the brake elements himself. The main thing is to buy original TDs.
Attention! If original brake discs are not available in auto stores in your city, then you can always order them from an online store, auto mechanics advise.
Article numbers of original brake discs on Niva Chevrolet:
- 21210-3501070-01;
- 21210350107001;
- 2121-3501070-01.
Knowing the TD article number, model and engine size of the Niva, you can select the necessary original brake elements.
Design features and purpose of Chevrolet Niva brake discs
Every car owner knows that the braking process involves friction. It helps reduce the speed of the car and stops its movement. The primary role in the braking process involving friction is played by the brake disc, which stops the movement of the wheels. This part can be cast iron, carbon fiber or ceramic. Chevrolet Niva is equipped with cast iron discs.
The car we are considering has brake discs on each wheel, which is why they are divided into front and rear. Their purpose is the same, but their design features are different. The rear discs are called drums with a shape corresponding to the name.
The Niva's front discs resemble a flat support, which is affected by working system elements. During the braking process, these elements heat up and eventually wear out.
The stronger the heating , the more worn out the disc is, so sooner or later the brake disc on the Niva will need to be replaced, which you can do yourself after reading this manual.

TD malfunctions
In what cases should brake elements be changed even if the car obeys the car owner:
- scratches. They appear due to the operation of the brake pad without coating. In this case, you need to change the pads. And only then look at the serviceability of the TD;
- steering wheel vibration when braking Niva Chevrolet. It indicates that the TD is deformed and must be urgently replaced;
- appearance of cracks. In this case, replacement is also required.
After the faults and brake elements to be replaced are identified, they are purchased strictly according to the article numbers, the Chevrolet Niva is driven into the pit and the procedure for replacing the brake parts is carried out.
Brake disc design
The operation of the braking system is based on the principle of friction. To reduce speed or stop the car, friction forces act on the brake disc, which slows down the wheels. Due to the fact that the disk is exposed to numerous loads, especially durable components are used to prevent rapid failure:
Brake discs come in different shapes, the rear ones are made in the form of drums, which is why they got the corresponding name. The front ones have a slightly different structure.
Made in the form of a flat disk, which is affected by the working elements of the brake system. During braking, pads made of a special material that can withstand wear and high heat that occurs during friction are pressed against the disc.
Front brake element replacement process
Tools you will need:
- jack;
- gloves;
- key;
- cleaner;
- screwdriver.
The process of replacing the front discs is as follows:
- Remove the wheel.
- Unscrew the screw at the lower brake flap.
- Bend the shield stoppers with a screwdriver.
- Remove the guide block bolts.
- Remove the shield and caliper.
- You hang the last one on a rope. This is necessary so that it does not interfere with you while installing a new disk.
- Remove the hub protection.
- Hold the last one and unscrew the nut.
- Remove the brake element.
- Install a new part and repeat the process in reverse order.
There are some nuances that need to be taken into account according to experienced mechanics. We'll tell you about them.
When replacing brake discs, it is recommended to replace the brake pads. Otherwise, the procedure will be incomplete and useless. Without new brake pads, the discs will quickly fail.
For your information! Experienced mechanics also recommend paying attention to the wear of the pads. If they are only slightly worn, then you can leave them alone and change only the TD.
In urban environments, brakes wear out faster than on highways. When changing disks, it is advisable to change all four APs. If testing shows that only two front or two rear ones are too worn out, then experienced mechanics recommend leaving a pair of discs that can still last twenty thousand kilometers.
The procedure for replacing brake discs on a Niva:
First, jack up the car and unscrew all 5 wheel nuts:
Then you will need to remove the brake pads. To do this, you will need pliers to remove the cotter pin from the clamp rod:
And again, use pliers to pull the rod outward to remove the caliper fixing plate. After this, lift the caliper up and remove the pads:
Then we take a 13mm wrench and unscrew the two bolts that secure the bracket, after spraying them with WD-40 lubricant.
And we remove the bracket from the brake disc with a slight movement of the hand, since nothing else holds it.
Before proceeding to the hub nut, first pry off the protective chrome cap with a screwdriver; you can even do this with light blows of a hammer on the end:
Now we take the knob and head and unscrew the hub nut, as shown in the photo below:
Replacing rear TDs
All the tools that are needed to change the front brake parts are also suitable for replacing the rear brake elements. Changing disks is done as follows:
- Place the Niva Chevrolet vehicle on a jack.
- Lift one side of it and remove the wheel.
- Unscrew the bolts on the brake drum.
- Remove the drum completely.
- Using a screwdriver, try to carefully pry and remove the tie bar and spacer.
- Rotate the shank of the front pad strut.
- Move the front block to the side.
- Remove the rear tension spring.
- Remove the rear pad support post.
Install a new disc and reassemble the Niva Chevrolet brake system in the reverse order of disassembly.
Now you know how to remove and install new brake discs on a Niva Chevrolet. However, sometimes car owners who are starting to repair their car for the first time encounter problems such as difficulties in removing the disc. He just stops and the person doesn’t know what to do next.
Niva's wheels are heating up - what to do in this case?
It happens that during operation the car wheels begin to heat up. This may indicate either their poor quality or breakdown.
Were you confused by the price of disc brakes and decided to buy a cheaper part? Then the heating problem can be solved very simply - replace the parts with better ones. In this case, you need to forget about saving. It is best if these are ventilated brake discs that match your “iron horse”.
Niva ventilated discs are parts with special holes and notches through which air passes and additional cooling occurs, preventing the brake disc from overheating. Such discs are very reliable, which has long been proven in practice. Most often, tire drivers choose brake discs from Brembo, Zimmerman, Delphi, Bosch and other manufacturers that have proven the quality of their products.

Having taken into account all the tips given above, you can be confident that the Niva, or rather its braking system, will never let you down and will work for your benefit for many years. This concludes the article about how to replace the front brake discs of a Chevrolet Niva. We can only hope that the new Chevrolet Niva will have fewer shortcomings and shortcomings in the braking system and that the designers will take into account the operating experience of the previous model. Good luck to everyone on the roads and safe driving.
PS: Watch the video with a review of the front brake discs and their replacement on a Chevrolet Niva from experienced car enthusiast Sergei Zykov.
What to choose: ventilated or non-ventilated wheels
Car owners often ask mechanics which wheels are better. Recently, the production and installation of ventilated APs has increased. Because they dissipate heat better than regular ones. This increases the lifespan of the brake elements.
Ventilated discs are larger in diameter than regular ones. Therefore, they are able to cool faster and improve braking. Such TDs are effective during sudden braking. In this case, the conventional mechanism overheats, the brake fails, and the Chevrolet Niva begins to rattle.
What to do if the Niva brake disc cannot be removed?
It often happens that the brake disc simply cannot be removed - it becomes stuck due to heat, rusts or sours due to dirt and scale. In this case, you have to use special pullers.
Experienced car mechanics remove the entire disc along with the fist and squeeze out the disc using a press.
If there is no puller, people often start hammering on the disc from the back side - sometimes this helps, but we do not recommend doing this. The edges of the brake disc simply break off from impacts.
If the disc cannot be removed because the pins cannot be knocked out, then you have to pick up a grinder and cut off the excess parts.
Below watch the video in which the author was unable to remove a disk using a homemade puller and used an angle grinder to remove the disk that was stuck on the hub. Sometimes this is the only option for the Chevrolet Niva - brute male power.

Removal of the front brake disc on a Niva Chevrolet car is carried out to replace it if its thickness has become less than the maximum permissible 9.5 mm, as well as if chips, cracks, deep scuffs are detected on the working surface, which increase wear on the pads, reduce braking efficiency, which causes vibration and beating. If traces of wear have formed on the surface from friction with the brake pads, that is, there is a deep chamfer along the edge of the disc, then it can be removed on a lathe by grooving, if the final thickness after this work is not less than permissible.
To carry out repair work, prepare a standard set of tools and perform the following sequence of actions:
- Place the side to be repaired on a jack and remove the wheel. Next, we dismantle the brake caliper, which in turn is hung on a rope so that it does not hang on the brake hose.
- Remove the brake pads. The pads must be marked so that during subsequent assembly they can be installed in their places.
- Next, unscrew the bolt securing the protective casing.
- Using small pliers or a flat-head screwdriver, bend the tendril of the locking plate of the upper and lower pad guide to the steering knuckle.
- Next, unscrew the upper and lower bolts securing the pad guide and remove the casing.
- Now remove the pad guide.
- Unscrew the hub nut.
- Remove the hub along with the brake disc.
- Now you need to separate them from each other. To do this, screw the nuts onto the studs so as not to spoil the threads and knock out the studs.
- Applying light blows with a hammer to the edge of the hub, we knock it out and separate it from the brake disc.
At this point, the repair work on removing and replacing the brake disc on a Niva Chevrolet car has been completed. Make the necessary repairs, then install in the reverse order.
Replacing Niva brake discs and pads (step-by-step instructions)
It's time to change your brake discs. The prerequisites for replacement are the beating (sometimes they grab, sometimes they don’t) of the front brakes. I bought wheels in Lipetsk for 1100 per pair. I bought the pads from Ferodo. I disassembled the brakes for the first time on the Niva, there is a difference with the Volga. After looking through the primer, I realized that I didn’t understand anything, so I began to figure it out directly on the machine itself. In principle, there were no difficulties, everything was easy and simple.

6. Next, I removed everything unnecessary from the disk and installed it on a new one.
7. Installed it on the hub, having previously lubricated it.
I started installing the pads.
8. We install the bracket and insert the pads into it.
9. Then we compress the pistons (I used a clamp) and install the caliper.
Things went faster on the right side because... already knew what and how.
