Remove, disassemble, inspect, reassemble, and install the caliper, and note these items:



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



To prevent dripping brake fluid, cover disconnected hose joints with rags or shop towels.



Clean all parts in brake fluid and air dry; blow out all passages with compressed air.



Before reassembling, check that all parts are free of dirt and other foreign particles.



Replace parts with new ones as specified in the illustration.



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.



When reusing pads, always reinstall them in their original positions to prevent loss of braking
efficiency.



Do not reuse drained brake fluid. Use only clean 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.



Do not mix different brands of brake fluid as they may not be compatible.



Coat the piston, piston seal groove, and caliper bore with clean brake fluid.



Replace all rubber parts with new ones whenever disassembled.



After installing the caliper, check the brake hose and line for leaks, interference, and twisting.
