REMOVAL & INSTALLATION
See Figures 1, 2, 3, 4, 5 and 6
- Raise the rear of the truck and support it with safety stands.
- Remove the wheel, brake drum, hub assembly, and brake shoes.
- Disconnect the brake hose from the wheel cylinder.
- Unscrew the wheel cylinder securing nut and remove the wheel cylinder from the brake backing plate.
- Install the wheel cylinder, assemble the remaining components, and bleed the brake hydraulic system.
See Figures 7, 8, 9 and 10
This is one of those jobs where it is usually easier just to replace the part rather than rebuild it. If you decide to rebuild the wheel cylinders, be sure you get the correct parts for your truck. Datsun obtains parts from two manufacturers: Nabco and Tokiko. Parts are not interchangeable. The name of the manufacturer is on the part.
- Remove the wheel cylinder from the backing plate.
- Remove the snapring from the piston bore.
- Remove the dust boot and take out the piston. Discard the piston cup. The dust boot can be reused, if necessary, but it is better to replace it.
- Wash all of the components in clean brake fluid.
- Inspect the piston and piston bore. Replace any components which are severely corroded, scored, or worn. The piston and piston bore can be polished lightly with crocus cloth. Move the crocus cloth around the piston bore; not in and out of the piston bore.
- Wash the wheel cylinder and piston thoroughly in clean brake fluid, allowing them to remain lubricated for assembly.
- Coat all of the new components to be installed in the wheel cylinder with clean brake fluid prior to assembly.
- Assemble the wheel cylinder and install it to the backing plate. Assemble the remaining components and bleed the brake hydraulic system.
