PARKING BRAKE ASSEMBLY INSPECTION


  1. INSPECT BRAKE DISC INSIDE DIAMETER


    1. A0160BP

      Using a brake drum gauge or an equivalent tool, 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 more than the maximum, replace the disc.

  2. INSPECT PARKING BRAKE SHOE LINING THICKNESS


    1. A0162BN

      Using a ruler, measure the thickness of the shoe lining.

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

      If the lining thickness is less than the minimum, or if there is severe or uneven wear, replace the brake shoe.

      Note

      Always replace both the upper and lower parking brake shoes together.

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


    1. A0160OE

      Apply chalk to the inside surface of the disc, then grind down the brake shoe lining to fit the disc.

      If the contact between the disc and the brake shoe lining is improper, repair it using a brake shoe grinder or replace the brake shoe.
