For the inspection procedure for the rear brake wheel cylinders, refer to the inspection procedure of the rear brake drum portion of this section.
REMOVAL & INSTALLATION
- Raise and safely support the vehicle on jackstands.
- Remove the brake drums, as described earlier in this section.
- Visually inspect the wheel cylinder boots for signs of excessive leakage. Replace any boots that are torn or broken.
A slight amount of fluid on the boots may not be a leak but may be preservative fluid used at the factory.
- If a leak has been discovered, remove the brake shoes and check for contamination. Replace the linings if they are soaked with grease or brake fluid.
- Disconnect the brake line from the wheel cylinder.
- Remove the wheel cylinder attaching bolts, then pull the wheel cylinder out of its support.
- Position the wheel cylinder onto the backing plate and install the retaining nuts to 75 inch lbs. (8.4 Nm).
- Attach the brake line to the wheel cylinder. Start the fitting by hand to prevent crossthreading it in the wheel cylinder. Tighten the brake line fitting to 115-170 inch lbs. (13-19 Nm).
- Install the brake drums and adjust the brake shoes, as described earlier in this section.
- Bleed the brake system, as described earlier in this section.
