HARRIER SERVICE MANUAL PART -1

BRAKES 26 FITTING SHOES ASSEMBLING Lightly smear the following parts with special grease as given. Keep the grease away from the shoe linings and all hydraulic parts. 1. Tips of new shoes - High melting point grease. 2. Hand brake strut slots - Graphite grease. 3. Adjuster Pushrod Threads - Mineral oil base grease. Note: When new shoe is fitted, ensure to fit new shoe return springs also. Always fit new shoes in pairs to both the sides of the vehicle. (RLH and RRH sides) Do not polish lining with sand paper or emery paper. If lining is polished with sand paper or emery paper, hard particles of sand paper will be deposited in the lining resulting in damage of drum surface. Brake Lining Standard Service Limit Lining Thickness above the rim 5.5 mm 1.0 mm Refer to the illustration. Assemble the Auto Adjuster (5.1, 5.2 & 5.3) to its minimum length. Assemble the abutment end spring (8) between the shoes. Place the shoes, springs along with adjuster in position on to the platforms of the back plate and locate the spring (8) below the riveted abutment plate and the shoes in the abutment groove. Hook the shoe return spring (7) (short length coil) to the leading shoe, with the adjuster assembly in its minimum length condition, assemble the adjuster assembly between the shoe webs. Attach the other end of the shoe return spring (7) to the opposite end of the Trailing shoe (3).Adjust the length of the adjuster until the shoes will clear the wheel cylinder pistons. Fit the pawl lever (18) to the spring dowel (20, 21, 22) inserting one leg of the pawl between male push rod end and shoe web of the leading shoe and the other end of the pawl leg resting on the adjuster nut (11).Hook the short end of the spring (19) into the hole in the pawl lever (18) and use pliers to attach the opposite end of the spring on to the shoe web (2). Fit the shoe hold down springs (6), cup washer (5) and pins (4) to both the shoes. Remove the elastic band from around the wheel cylinder and reduce the length of the adjuster assy. until the shoes rest on the wheel cylinder pistons. Fit the hand brake cable to the lever on the trailing shoe, ensuring the cable is correctly located in the end of the lever. Note: The cable should just be tight without pulling the hand brake lever from the 'fully off' position. Ensure that the shoe linings (2/3) are free from oil and grease. During servicing of shoes/replacement, the brake dia. overshoes should be set to 294 to 294.5 mm by adjusting the ratchet. This is to have minimum clearance between shoes and drum. Clean the exterior of the drum with a wire brush and wipe the inside with a clean rag. Note: If the drum looks poor in condition, or is scored inside where the brake shoes contact, fit a new drum. Offer the drum to the brake and adjust the length of the adjuster until it is only just possible to fit the drum over the brake shoes. Check the pawl is in contact with the adjuster nut on the adjuster and fit the drum. Repeat procedure with the opposite rear brake and operate the foot brake through its full stroke 10 to 20 times. Check the movement of the hand brake and road test the vehicle.
