Execution sequence
1. We prepare the car for work (see «Preparing the car for maintenance and repair»).
Warning! When the brake pistons are sunk into the cylinders, the level of brake fluid in the reservoir will increase, so pump some of the brake fluid out of the reservoir. After replacing the brake pads, check and, if necessary, top up the brake fluid level (see «Checking the levels of technical fluids»).
2. Remove the reservoir cap of the main brake cylinder and pump out some of the liquid with a rubber bulb.
3. Remove the wheel (see «Wheel - replacement»).
4. Disconnect the parking brake cable from the rear brake caliper (see «Parking brake cables - replacement»).
5. With a 13 mm key, we unscrew the lower caliper mounting bolt.
6. Remove the bolt.
7. Remove the lock washer.
8. Using a screwdriver, lift the caliper up, turning it on the axis of the upper guide.
9. Without disconnecting the brake hose, move the caliper along the guide and remove it from the trunnion bracket.
10. We fix the caliper so as not to subject the brake hose to stress.
11. Using a slotted screwdriver, remove the brake pads.
Recommendation. When replacing brake pads, be sure to check the thickness and condition of the brake disc (see «Rear disc brakes - check»).
12. Using a special tool, screw the piston into the cylinder.
Warning! Push piston into caliper (as on the front brake mechanism) unacceptable! This will inevitably lead to damage to the caliper and its subsequent replacement. On the rear brake mechanisms, the piston must be recessed with simultaneous rotation.
13. We combine one of the cutouts on the piston with the protrusion on the caliper.
14. With a metal brush, clean the guide pads of the caliper and the edge of the brake disc.
15. We apply a special high-temperature grease to the contact points of the pads with the seating surfaces of the caliper bracket.
16. We apply a special high-temperature grease to the two caliper guides, they should move freely along the bracket bushings.
17. Install the brake pads in reverse order.
18. Similarly, we replace the brake pads on the other side of the car.
19. Press the brake pedal several times to self-adjust the brake pads.
20. We check the level of brake fluid in the reservoir of the main brake cylinder and, if necessary, bring it to normal (see «Checking the levels of technical fluids»).
