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. Brake pad wear indicator; 6. Pads; 7. External gasket (lubricate both sides of the gaskets with Molykote M77 grease)
1. Drain some of the liquid from the tank.
2. Raise the vehicle and remove the rear wheels.
3. Unscrew the lower bolt and tilt the caliper upward.
4. Remove the brake shoe linings, brackets and shoes.
5. Install the pads in place. If the pads are being changed, press the pistons into the caliper cylinder using a clamp or a special mandrel.
6. Clean the disc and caliper and check the condition of these parts (presence of cracks, signs of wear and damage)
7. Carefully, so as not to tear the rubber boots of the pistons and pin, lower the caliper, tighten the bolt with a torque of 23 Nm.
8. Check the fluid level in the tank and 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 "hard". Pressing harder on the pedal is highly discouraged, as the piston seals may be damaged due to friction against worn cylinder walls.
10. Brake pads are worn in to the disc after approximately 300 km of driving.
Examination
The brake pads should be checked after 9600 km, i.e. every time the engine oil is changed (it is also recommended to check the pads every time the wheel is removed). Check the condition of the pads by looking from both sides of the caliper. Check the thickness of the inner pad. On the part of the inner pads on the side of the steel plate there is a heat-conducting layer, which is pressed into the friction material of the pad during manufacture. The presence of this layer, in appearance, creates the erroneous impression of increased wear of the pad. Check the remaining pad thickness through the opening in the top of the caliper. Replace the pads if the thickness of at least one pad is less than 0.76 mm.
