Wheel Cylinder Removal and Installation

NOTE: Before proceeding, review Service Precautions.

REMOVAL
With brake drums removed, inspect the wheel cylinder boots for evidence of a brake fluid leak. Visually check the boots for cuts, tears, or heat cracks. If any of these conditions exist, the wheel cylinders should be completely cleaned, inspected and new parts installed.

1. In case of a leak, remove brake shoes (replace if soaked with grease or brake fluid.)





2. Disconnect rear brake flex hose tube from wheel cylinder and remove the flex hose routing bracket from the brake support plate.





3. Remove rear wheel cylinder attaching bolts. Then pull wheel cylinder assembly off brake support plate.

INSTALLATION
1. Apply a small bead of silicone sealer around the mating surface of the wheel cylinder to brake support plate.
2. Install wheel cylinder onto brake support plate. Tighten the attaching bolts to a torque of 13 Nm (115 inch lbs.).
3. Hand start the hydraulic brake hose tube fitting into the wheel cylinder. Tighten the tube nut to a torque of 17 Nm (145 inch lbs.).
4. Install brake shoes on support plate.
5. Install rear brake drum onto rear hub.
6. Install the wheel and tire assembly. Tighten the wheel mounting stud nuts in proper sequence until all nuts are torqued to half specification. Then repeat the tightening sequence to the full specified torque of 129 Nm (95 ft. lbs.).
7. Adjust the rear brakes.
8. Bleed the entire brake system.
