Calipers - Visually inspect calipers for brake fluid leakage,
damaged or defective pistons or piston boots. If
there is evidence of leakage, damage, or other
defects the caliper should be replaced or
repaired.
Disc brake rotors - Visually inspect rotors for scoring, warp-
ing, cracks, bluing or heat spots or other damage
or defects. If signs of damage or defects are
found, the rotor(s) should be resurfaced or
replaced in accordance with the vehicle manu-
facturer's recommended service procedure.
Anchor plates - Visually inspect anchor plates for worn or
damaged slippers, damaged or dislodged guide
pin boots or other defects. If signs of wear, dam-
age or defects are found, the anchor plate(s)
should be repaired or replaced.
