- Inspect the brake caliper
housing (1) for cracks, excessive 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 piston(s) into the caliper bore(s):
 
The movement of the caliper piston(s) into the caliper bore(s) 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. |
