Removing
1. Raise the front of the car and secure it on stands. Remove the wheel.
2. Use a clamp to pinch the brake hose.
3. Clean the area around the brake hose connector and caliper. Unscrew the hose from the caliper.
4. Remove the brake pads.
5. If necessary, unscrew the caliper holder mounting bolts.
6. Remove it from the hub.
Caliper repair
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. When installing the piston, the lugs on the piston must be vertical.
9. Install the guide bushings into the caliper body.
Installation
1. If the caliper holder was removed, install it on the steering knuckle and secure with bolts to the required torque. Screw the caliper onto the brake hose.
2. Install the caliper onto the caliper holder. Remove air from the brake system.
3. Install the wheel and lower the car.
