Check the inside of the brake drum. Slight wear on the drum from the action of the pads is normal.
Measure the inner working surface of the drum in several places. Compare the results of the obtained measurements. Thus, the optimal gap between the pads and the drum is automatically maintained.
Perform the work on a car with the rear wheels hanging on a lift or a car mounted on supports using a jack. Compress by tightening the bolts evenly into the two threaded holes of the drum. With the car stationary on the ground, press the brake pedal 2-3 times to move the shoes to the drum.
Niva Chevrolet replacement of rear brake pads, cylinders and drums. Video and photo instructions
We have a Chevrolet Niva car, produced in 2005, mileage 137 thousand km, for scheduled repairs, on which it is necessary to replace the rear brake pads, drums and cylinders. We will show you how you can do this yourself, without resorting to the help of specialists.
It looks like the pad on the rear left wheel has been torn off, there is a grinding noise when braking, and when reverse gear is engaged, the wheel jams and then breaks. Therefore, it was decided to immediately lift and change the pads, drums and cylinders on both sides. After this, we'll bleed the brakes with a vacuum.
It really didn’t work out for us, all the threads remained on the bolts, it was very soured, so a hammer comes to the rescue, since we will eventually have to change the drum anyway. This situation arises when, when replacing fasteners, they are not coated with copper grease; I believe that there is no need to save on this!

Using a 10mm wrench, loosen and then unscrew the fitting. Be prepared, brake fluid will flow. We install and screw on the new brake cylinder. We lubricate all fastening bolts with copper grease so that in the future we will not have problems with unscrewing.
We assemble new brake pads, we have them from TRIALLI, spare parts catalog number GF-232, put on the handbrake cable and put them in place.
We loosen it so that our new brake pads press against the cylinder. Since the pads are now compressed, the new brake drum should fit easily. We install the drum from TRIALLI, its number is TF-078. Before installation, we knock off the accumulated dirt on the seat with a brush with metal bristles, then lubricate it with copper grease. Place the drum and assemble in reverse order.
Since we drained the brake fluid a little, we need to bleed the brakes; if you did not touch the cylinders, then you do not need to do this. We will pump, or rather remove, air from the system using a special vacuum device. In the video you can see how this process works.

Societies › Chevrolet Niva › Blog › How to remove rear brake drums?
Hello everyone, now I wanted to change the rear brake pads. As annoying as it may sound, I was unable to remove the drum. How to remove them correctly?
Thanks for the advice on hanging and heating the drum. On my own behalf, I would like to add that there is a slight play on the heels, so the wheel spins back and forth and then almost jumps off on its own. Thanks again, I spent half a day today tapping around the perimeter through the wood of the cup, still a little free
Better sum it up: 1. VD-40, 15 minutes, VD-40, 15 minutes.2. Try the trick with hanging and accelerating and braking. It's not that tight. (If you miss everything, then about 0.5 mm on the studs moves.)3. Knock on a piece of wood through the installation, but this is more convenient with two people, because... there are not enough hands. Put a piece of wood on the drum, put the assembly on top and hit it - this way it turns out more evenly than with a piece of wood.
Using this method, everything worked out :)).

With change inevitable, the question is how to take off
the attached brake drum often becomes vital. And you don’t even have to blame the Russian auto industry. drums for foreign cars are welded. Of course, it rides for a while and so on. All this slows down the car unnecessarily, the sounds at times seem downright scary, but you can agree with this if you do not understand how dangerous it is to joke with the brakes.
Some will say that this is great, let's say change the pads more often, you won't soon remember the drum. And he will be right! But later, but this must be remembered. The longer a replacement part lasts, the more likely it is to be similar to the car. Therefore, the method described in each manual (screwing the holes and pushing the drum) is remembered only by hopeless optimists.

Before you take the sledgehammer, it would be wise to go over the hub with a steel brush. The salt and dirt from the cement is wrapped along the rim at a good level of the concrete. After cleaning, the centering belt is treated with something like WD-40. There is no need to hit one place with all your might. firstly, it is possible to tilt the, as it is called, bend of the drum, and it will be even more difficult to remove, and secondly, of course, destroy what should not be changed. However, you need to gently tap in a circle, while peeling off not the metal, but the strip, which will act as a gasket.
If the drum has become too stubborn for you, you will have to take constructive measures. Considering that they are associated with the highest degree of threat, the machine's locking must be reliable and checked a couple of times.
The following actions:
- Get behind the wheel, start the car, engage second or third gear and release the clutch. The raised part of the axle will begin to move,
and so will the drum - Rewind the engine to 3000 rpm in some places;
- Slam on the brakes;
- Another 10 seconds you fill with gas;
- Stop the engine and remove the drum.

A force majeure situation develops if the drum is not very stuck, but at the same time the brake cylinder is completely jammed. Neither brake gas nor a sledgehammer will help here. You have to take a drill and drill holes (small, 2-3 mm) at the junction of the drum and the shaft axis. Brake fluid is poured into it. and again it’s the sledgehammer’s turn.

Removing a soured brake drum VAZ 2123 / Russian crazy service car
In this video I show how to remove a drum that has become soured on the axle shaft. Special pullers couldn't cope with this.
Having learned from the “bitter” experience of the previous 10, having driven the tires from the passenger compartment, the very first thing I did was remove the drums. I coated the seats with graphite. Such questions no longer arise! ! ! and also loosened all the nuts on the brake pipes, including the ABS unit, one by one. made it possible to lubricate the brake nut contact.
