Loosen both bolts indicated by arrows to remove the handbrake cable mount.
Replacing brake pads
1. Raise the rear of the vehicle.
2. Remove the wheels.
3. Remove the two tabs shown in the illustration on the inside of the caliper to remove the handbrake cable fasteners and the retaining spring.
4. Remove the lower caliper guide pin from the caliper to release it from the mounting frame.
5. Fold the entire caliper up as shown in the illustration below and tie it with a piece of wire to the rear suspension so that it cannot fall.
Removing the rear disc brake pads. Tie the caliper with wire as shown.
6. Remove the inner and upper intermediate plates and both brake shoes.
7. After removing the pads, do not press the brake pedal, as the piston will pop out.
8. Replace the brake pads when the lining material thickness reaches 2.0 mm. Never replace just one pad or switch the pads from one side to the other illustrations shows where the thickness of the pads is measured. A brake pad repair kit includes certain parts that must all be used during installation.
9. Clean the calipers with brake fluid or alcohol. Never use gasoline for this purpose.
10. Check that the piston gaskets are sealing well.
11. Check the brake disc for deep grooves, which are caused by worn brake pads. Measure the thickness of the brake disc with a micrometer as shown in illustrations. If the disc thickness is less than the specified value, the disc should be replaced. Only one disc can be replaced, but in most cases both discs need to be replaced.
12. Installation of brake pads is carried out in the reverse order of removal, taking into account the following points:
13. Using sharp pliers, turn the piston clockwise into the caliper, as shown in the illustration below. At the same time, do not allow the fluid to overflow from the expansion tank, i.e. you need to monitor the fluid in the tank. If the piston is deep in the cylinder, there is enough space to install new pads.
Before installing the brake pads, screw the piston into the hole using pliers.
14. Insert the inner pad with the intermediate plate, pull the caliper outward and insert the outer brake pad with the intermediate plate.
15. Untie the caliper and lower it down without damaging the inserted brake pads.
16. Insert the bolt (see illustration) and tighten to 22 - 32 Nm.

17. After installation, press the brake pedal several times and check whether air has entered the system. Otherwise, the system should be bled as described in Section Bleeding the brakes.
Brake caliper repair
Repairing the rear disc brake caliper is a little more complicated than the front, as the adjustment mechanism is on the inside of the caliper. Since the caliper must also be disassembled almost completely to get to the cylinder gasket, a repair description is not provided. To completely remove the caliper, follow the steps described in the previous step, but this time remove the upper and lower bolts that hold the caliper to the mounting frame. Loosen the hollow brake line bolt and remove both copper washers. The washers should always be replaced.
The mounting frame can be removed. It contains guide pins and rubber seals that can be replaced. Tighten the mounting frame bolts to 35-45 N·m.
