PARKING BRAKE ASSEMBLY INSPECTION

PROCEDURE

1. INSPECT BRAKE DISC INSIDE DIAMETER

   
   

   1. 

      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 rear disc.

2. INSPECT PARKING BRAKE SHOE LINING THICKNESS

   
   

   1. 

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

      Standard Thickness
      2.55 mm (0.1004 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 parking brake shoe assembly.

      Note

      Always replace both right and left parking brake shoes together.

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

   
   

   1. 

      Apply chalk to the inside surface of the disc, then slide the brake shoe against the disc to check the fit of the brake shoe lining to the disc.

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

      Note

      
      

      • Always replace both right and left parking brake shoes together.

      • Wipe off the chalk after inspection.
