REAR BRAKE INSPECTION


  1. INSPECT BRAKE DRUM INSIDE DIAMETER


    1. B007UFS

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

      Standard inside diameter
      Item Specified Condition
      for 254 mm drum: 254 mm (10.000 in.)
      for 295 mm drum: 295 mm (11.614 in.)
      Maximum inside diameter
      Item Specified Condition
      for 254 mm drum: 256 mm (10.079 in.)
      for 295 mm drum: 297 mm (11.692 in.)

      Tech Tips

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

  2. INSPECT BRAKE SHOES LINING THICKNESS


    1. B007R0M

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

      Standard thickness
      Item Specified Condition
      for 254 mm drum: 5.1 mm (0.201 in.)
      for 295 mm drum: 6.0 mm (0.236 in.)
      Minimum thickness
      1.0 mm (0.0394 in.)

      Tech Tips

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

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


    1. B007SWJ

      Apply chalk to the inside surface of the drum, then grind drum on the brake shoe lining to fit.

      Tech Tips

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

  4. INSPECT BRAKE WHEEL CYLINDER


    1. Check the cylinder bore and the piston for rust or scoring.

      Tech Tips

      If necessary, replace the wheel brake cylinder assembly.
