7. REMOVE REAR SHOE (a) Slide out the rear shoe. (b) Disconnect the parking brake cable from the parking brake shoe lever. INSPECTION AND ADJUSTMENT OF PARKING BRAKE COMPONENTS 1. MEASURE BRAKE DRUM INSIDE DIAMETER Standard inside diameter: 167 mm (6.57 in.) Maximum inside diameter: 168 mm (6.61 in.) If the drum is scored or worn, the brake drum may be lathed to the maximum inside diameter. 2. MEASURE BRAKE SHOE LINING THICKNESS Standard thickness: 2.0 mm (0.079 in.) Minimum thickness: 1.0 mm (0.039 in.) If the shoe lining is less than minimum, replace the parking brake shoes. NOTE: In order to maintain effective brakes, replace all of the shoes if the thickness of any one is not within specification. 3. INSPECT REAR PARKING BRAKE LINING AND DRUM FOR PROPER CONTACT Replace the brake or lathe the brake disc as necessary. 4. MEASURE CLEARANCE BETWEEN PARKING BRAKE SHOE AND LEVER Using a feeler gauge, measure the clearance. Standard clearance: 0 — 0.35 mm (0 — 0.0138 in.) If the clearance is not within specification, replace the shim with one of the correct size. Thickness mm (in.) Thickness mm (in.) 0.3 (0.012) 0.9 (0.035) 0.6 (0.024) Shim Clearance
