      *1 Brake Drum Gauge

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

      Standard inside diameter
      228.6 mm (9.000 in.)
      Maximum inside diameter
      229.6 mm (9.039 in.)

      If the inside diameter is greater than the maximum, replace the brake drum.

  2. INSPECT REAR BRAKE SHOE LINING THICKNESS

      *1 Ruler

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

      Standard thickness
      5.0 mm (0.197 in.)
      Minimum thickness
      1.0 mm (0.0394 in.)

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

      Note

      If the brake shoes need replacing, they must be replaced as a set.

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

    Check the cylinder bore and piston for rust and scoring.
