To assess the condition of the brake pads without removing the drum, there is an inspection window in the brake shield.
We remove the plug from the shield.
To replace the pads, place the car on a viewing pit or lift. Remove the rear wheel and loosen the parking brake system drive cable (see Adjustment and removal of parking brake system components).
Before unscrewing the bolts securing the brake drum to the axle flange, tap their heads.
Bolts with a reduced head height are used to fasten the brake drum. Therefore, to unscrew them, it is better to use a hexagonal tool head, in which the working edges start immediately from its end (if necessary, the head can be faceted).
Using a 12 mm socket, unscrew the two bolts securing the brake drum to the axle shaft.
To remove the drum, the removed bolts can be screwed into the two threaded holes of the drum (unlike the mounting holes, the threaded holes are arranged symmetrically). When tightened, the bolts will rest against the axle flange and shift the drum.
We screw the bolts into the threaded holes.
You can also remove the drum,…

...by striking the end of the drum with a hammer through a wooden block. We strike evenly, turning the drum.
We remove the drum.
We show two ways to remove brake pads.
When removing using the first method…
…use a screwdriver to disconnect the end of the upper tension spring from the shoe…
…and we take out the spring.
We remove the spacer bar.
Using pliers, turn the tailpiece of the front brake shoe until it aligns with the slot in the outer cup.
We remove the spring with the outer and inner cups.
On the other side of the brake shield we take out the stand.
Elements of the support stand of the shoe.
We move the front shoe away..
…and remove the lower tension spring.
We remove the rear brake shoe support.
We move the rear brake shoe away..
…and we remove the manual brake pad drive lever from the end of the rear parking brake cable.
When removing the brake pads using the second method, we remove the support posts of both pads.
We pry off the rear brake shoe with a screwdriver (or pull it with your hand) and we remove its lower stop from the support plate.
We lower the brake pads down with our hands, removing their upper stops from the slots of the wheel cylinder pistons.
We remove the lower tension spring.
We remove the pads together with the spacer bar and spring from behind the axle flange.
We carry out the operation carefully so as not to damage the wheel cylinder dust boots.
We remove the manual brake pad drive lever from the end of the rear parking brake cable..
…and remove the brake pads with the spacer bar and the upper tension spring.
Holding one of the blocks on the floor with your foot, we stretch the spring..
…and we remove the spacer bar from the stop.
We remove the upper tension spring.
To remove the brake pad manual release lever…
…we remove the cotter pin from its axle.
We remove the washer,…
…lever…
…and we take out the axle.
Assembly and installation of the pads is carried out in the reverse order (depending on the method of disassembly). In the second method, before installing the second brake pad, we fix the first one from moving by installing a support stand.
When installing new pads, it is necessary to press the pistons into the wheel cylinder. This operation can be performed as follows:
carefully striking the piston with a hammer through a wooden block..
...or having installed the pads, we press on them, leaning two mounting blades on the flange of the brake shield. In this case, the upper stops of the pads press the pistons into the cylinder.
After installing new brake pads, it is necessary to adjust the parking brake system (see Adjustment and removal of parking brake system components).
