REAR BRAKE (for Leading Trailing Shoe Type) INSPECTION


  1. MEASURE BRAKE DRUM INSIDE DIAMETER

    A01KEYK

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

      Maximum inside diameter
      297.0 mm (11.693 in.)
      Standard inside diameter
      295.0 mm (11.614 in.)

      If the drum is scored or worn, the brake drum may be lathed to the maximum inside diameter.

  2. MEASURE REAR DRUM BRAKE SHOE LINING THICKNESS


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

      Standard thickness
      6.5 mm (0.256 in.)
      Minimum thickness
      1.0 mm (0.039in.)

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

  3. INSPECT BRAKE DRUM AND REAR DRUM BRAKE SHOE LINING FOR PROPER CONTACT

    A01KFT8

      If the contact between the drum and the shoe lining is improper, repair it with a brake shoe grinder or replace the brake shoe assembly.
