- 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.
- Inspect the caliper piston dust boot seal (4) 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.
- Inspect the 2 (phenolic) caliper pistons (3) for cracks or signs of damage.
- Inspect for brake fluid leakage around the caliper piston dust boot seal (4)
and on the disc brake pads. If there is any evidence of brake fluid leakage, the
brake caliper requires overhaul or replacement.
- Inspect for smooth and complete travel
of the caliper pistons into the caliper bores:
The movement of the caliper pistons into the caliper bores should be smooth
and even. If the caliper piston is frozen or difficult to bottom, the caliper requires
overhaul or replacement.
- For dual piston caliper applications, insert a discarded inner brake
pad (2) or block of wood in front of the pistons. 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 into the bores.
