BR–37 BRAKE SYSTEM – REAR BRAKE (Parking Brake) 3. MEASURE BRAKE DISC INSIDE DIAMETER Using a vernier caliper, measure the inside diameter of the disc. Standard inside diameter: 190 mm (7.48 in.) Maximum inside diameter: 191 mm (7.52 in.) Replace the disc if the inside diameter is at the maximum value or more. Replace the disc or grind it with a lathe if the disc is badly scored or worn unevenly. 4. INSPECT PARKING BRAKE LINING AND DISC FOR PROPER CONTACT Apply chalk to the inside surface of the disc, then grind down the brake shoe lining to fit. If the contact between the disc and the brake shoe lining is improper, repair it using a brake shoe grinder or replace the brake shoe assembly. 5. MEASURE CLEARANCE BETWEEN PARKING BRAKE SHOE AND LEVER Using a feeler gauge, measure the clearance. Standard clearance: Less than 0.35 mm (0.0138 in.) If the clearance is not within the specification, replace the shim with one of the correct size. Thickness m(in.)
