Rear disc brake pads: 1. Piston; 2. Lubricate both sides of the gaskets with Molykote M77 grease; 3. Inner lining B; 4. Inner lining A; 5. Pad wear indicator; 6. Pads; 7. Outer lining (lubricate both sides of the gaskets with Molykote M77 grease)
1. Drain some of the fluid from the reservoir.
2. Raise the car and remove the rear wheels.
3. Turn away the lower bolt and cast away a support upwards.
4. Remove the brake pads, calipers and pads.
5. Install pads in place. If the pads are changed, then sink the pistons into the caliper cylinder with a clamp or a special mandrel.
6. Clean the disc and caliper and check the condition of these parts (cracks, signs of wear and damage)
7. Carefully, so as not to tear the rubber boots of the pistons and fingers, lower the caliper, tighten the bolt with a torque of 23 Nm.
8. Check the fluid level in the tank, top up if necessary.
9. After installing the calipers, press the brake pedal a little so that the pedal travel does not exceed 50 mm until the pedal becomes "tough". Pressing the pedal harder is highly discouraged, as piston seals can be damaged due to friction against worn cylinder walls.
10. Brake pads run in to the disc in about 300 km.
Examination
The pads should be checked after 9600 km, i.e. at every engine oil change (It is also recommended to check the pads each time the wheel is removed). Check the condition of the pads by looking at both sides of the caliper. Check the thickness of the inner pad. A heat-conducting layer is provided on the part of the inner pads on the side of the steel plate, which is pressed into the friction material of the pad during manufacture. The presence of this layer in appearance causes an erroneous impression of increased pad wear. Check the remaining pad thickness through the opening in the top of the caliper. Replace pads if at least one pad is less than 0.76 mm thick.
