Caliper repair
The correct location of the piston in the rear caliper
1. Be careful to clean the brake caliper of brake dust and dirt.
2. Remove the piston from the caliper by using low pressure air supplied to the brake cylinder through the brake hose connection hole. At the same time, instead of brake pads, install a wooden block.
3. Remove the O-ring from the groove in the caliper bore.
4. Press the guide bushings out of the caliper body.
5. Wash all parts in methanol or clean brake fluid and wipe dry.
6. Dip the piston and new piston o-ring in the brake fluid and apply a thin layer of brake fluid to the piston hole in the caliper.
7. Install the o-ring into the caliper bore.
8. Install the dust cover on the piston so that the inner diameter of the cover fits into the piston groove. Insert the piston into the caliper and at the same time push the outer edge of the dust cover into the caliper until it locks into place.
Installation
1. Install the caliper on the brake disc, then screw on the brake pipe.
2. Coat the threads of the caliper mounting bolts with a tool that prevents them from unscrewing and secure the caliper with bolts.
3. Install the brake pads.
4. Finally tighten the brake line nut.
5. Remove air from the brake system.
6. Install the wheel and lower the car.
