Be sure to keep the parking brake down when you raise the vehicle, while servicing and repairing the wheel cylinder. Press on the brake pedal until you've gone past the first inch, then use a brake pedal manometer to keep the master cylinder from draining. Raise the vehicle so you can take off the tire and wheel. Remove the nut at the wheel cylinder from the flex hose tube and unscrew the hose from the brake caliper after capping its end with the adapter. Remove the
Brake Drum and unbolt the wheel cylinder. Carefully pull the wheel cylinder and seal out of the space between the brake shoes and support plate. For installation, stick the seal onto the wheel cylinder mounting surface and fix the wheel cylinder between the brake shoes on the support plate, tighten all the mounting bolts to 13 Nm (115 inch lbs.). After measuring the brake shoes to the size of the brake drum, install the brake drum. Place the nut on the flex hose tube into the wheel cylinder, then tighten it to 17 Nm (145 inch lbs.) torque. Retrieve the tire and wheel and apply 135 Nm (100 ft. lbs.) to the wheel mounting nuts as you put the tire assembly back on. Turn the wheel while applying very light pressure, so that the brake drum lightly scrapes the shoes; then take off the brake pedal depressor and take out your wheel. When needed, bleed the wheel cylinder or circuit, take the vehicle on a road test and ensure it stops efficiently in both directions, with the automatic-adjuster adjusting the brakes while driving.
