Brake Caliper Inspection

Brake Caliper Inspection





1. Inspect the brake caliper housing (1) 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 section for cracks, tears, cuts deterioration and 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 piston dust boot seal (2) and on the disc pads. If there is any evidence of brake fluid leakage, the brake caliper requires overhaul or replacement.





4. Inspect smooth and complete travel of the caliper piston or pistons, into the piston 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.
^ For single piston caliper applications, insert a discarded inner brake pad (2) or block of wood in front of the piston. Using a large C-clamp (1) installed over the body of the caliper (3) and against the brake pad or block of wood, slowly bottom the piston in the bore.
^ For dual piston caliper applications. Insert a discarded inner brake pad (2) or block of wood in front of the piston. Using 2 large C-clamps (1) installed over the body of the caliper (3) and against the brake pad or block of wood, slowly bottom the pistons evenly in the bores.
