1. CHECK BRAKE DISC INSIDE DIAMETER


    Toyota Rav4. Aca30, 33, 38 Gsa33 Zsa30, 35

  1. Using a drum gauge or equivalent, measure the inside diameter of the disc.

    Standard inside diameter:
    173 mm (6.81 in.)
    Maximum inside diameter:
    174 mm (6.85 in.)
    If the inside diameter is greater than the maximum, replace the disc.

    Standard thickness:
    3.5 mm (0.138 in.)
    Minimum thickness:
    1.0 mm (0.039 in.)
    If the shoe lining thickness is equal to or less than the minimum, replace the brake shoe assembly.

  1. Apply chalk to the inside surface of the disc. Touch the brake shoe to the disc and check that there is full contact between the brake shoe and disc (white chalk is transferred to the entire brake shoe).
    If the contact is not as specified, use a shoe grinder to repair the brake shoe, or replace the brake shoe assembly.
