Brake Caliper: Testing and Inspection

Brake Caliper Inspection





Caution: Refer to Brake Dust Caution in Service Precautions.

Caution: Refer to Brake Fluid Irritant Caution in Service Precautions.

1. Inspect the brake caliper housing (5) for cracks, excess wear, and/or damage. If any of these conditions are present, the brake caliper requires replacement.
2. Inspect the caliper piston dust boot seal (2) for cracks, tears, cuts, deterioration and/or improper seating in the caliper body. If any of these conditions are present, the brake caliper requires overhaul or replacement.
3. Inspect for brake fluid leakage around the caliper piston dust boot seal (2) and on the disc brake pads. If there is any evidence of brake fluid leakage, the brake caliper requires overhaul or replacement.





4. Inspect for smooth and complete travel of the caliper piston, or pistons, into the caliper bore, or bores: The movement of a caliper piston into a caliper bore should be smooth and even. If a caliper piston is frozen or difficult to bottom, the caliper requires overhaul or replacement.
5. Push the disc brake caliper piston into the caliper bore using an old inner disc brake pad and a disc brake piston installation tool.
