- 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 (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.
- 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.
- 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 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 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. |
