Rear Brake Caliper: Disassembly

WARNING:

Frequent inhalation of brake pad dust, regardless of material composition, could be hazardous to your health.

Avoid breathing dust particles.
Never use an air hose or brush to clean brake assemblies. Use an OSHA-approved vacuum cleaner.

NOTICE:

Do not spill brake fluid on the vehicle; it may damage the paint. If brake fluid does contact the paint, wash it off immediately with water.

NOTE:

Clean all parts with brake fluid and air dry; blow out all passages with compressed air.
Make sure no dirt or other foreign matter gets in the brake fluid.
Make sure no grease or oil gets on the brake discs or pads.
Do not reuse the drained fluid. Use only new Acura DOT 3 Brake Fluid from an unopened container. Using a non-Acura brake fluid can cause corrosion and shorten the life of the system.
Coat the piston, the piston seal groove, and the caliper bore with clean brake fluid.
Use recommended greases in the rear caliper set.
After installing the caliper, check the brake hose and line for leaks, interference, and twisting.
Refer to the Exploded View as needed during this procedure.
