PARKING BRAKE ASSEMBLY INSPECTION


  1. INSPECT BRAKE DISC INSIDE DIAMETER


    1. A01CCAB

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

      Standard inside diameter
      190 mm (7.48 in.)
      Maximum inside diameter
      191 mm (7.52 in.)

      If the inside diameter is greater than the maximum, replace the disc.

  2. INSPECT PARKING BRAKE SHOE LINING THICKNESS


    1. A01CBPB

      Using a ruler, measure the shoe lining thickness.

      Standard thickness
      2.45 mm (0.0965 in.)
      Minimum thickness
      1.0 mm (0.0394 in.)

      If the shoe lining thickness is equal to or less than the minimum, or If there is severe or uneven wear, replace the parking brake shoe assembly.

      Note

      Always replace both the right and left parking brake shoes as a set.

  3. INSPECT BRAKE DISC AND PARKING BRAKE SHOE LINING FOR PROPER CONTACT


    1. A01CFE1

      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.
