Brake Caliper Piston, Removing And Installing, Four-Piston Brake: Removing
- Brake caliper removed and separated from the hydraulic system. Refer to BRAKE CALIPER, REPLACING, ALL BRAKES EXCLUDING 1LC, 1LE, 1LF .
TIP:
Make sure that the paint coat on the brake caliper is not damaged when removing the brake caliper pistons and the protective caps.
-- Tension the brake caliper in a vise with protective covers over the jaws.
Leaking brake fluid increases the risk of injury.
Irritation and injury to the skin and eyes are possible.
- Wear protective eyewear.
- Wear safety gloves.
-- Place a cloth over the brake caliper chamber to catch any spraying brake fluid. Place another cloth tightly around the compressed air gun nozzle on the brake caliper.
Risk of injury due to sudden release of the brake caliper piston when pressing out.
- Never reach with the fingers into the brake caliper opening.
TIP:
Only one brake caliper piston can be pressed out at a time.
-- Hold the opposite brake caliper piston firmly in the brake caliper -1- using the Piston Resetting Tool -T10145- -A-.
-- To prevent damage to the brake caliper paint coating, place a piece of rubber between the Piston Resetting Tool -T10145- and the brake caliper.
-- Block the other brake caliper pistons using wooden blocks -C-, for example. Also place a protection -B- in front of the Piston Resetting Tool -T10145- -A- so that the brake caliper piston does not become damaged when being pressed out.
- The bleed screws are closed.
-- Position the compressed air gun nozzle -D- to the hole for the brake hose and press the brake caliper piston -3- out of the brake caliper with compressed air.
-- Carefully pry the protective cap -1- and the seal out of the brake caliper with the Removal Tool -T40338- -2- using gentle lifting movements, and do not damage the groove for the protective cap in the brake caliper while doing so.
-- When removing, make sure that the piston wall surface is not damaged.
-- Repeat the work procedure on the next brake caliper piston.
