Wheel Cylinder: Service and Repair
Removal1. Perform steps 1. to 5. of BRAKE DRUM REMOVAL.
2. Perform steps 2. and 4. of BRAKE SHOE REMOVAL.
3. Loosen brake pipe flare nut (or nuts) but only within the extent that fluid does not leak.
4. Remove wheel cylinder mounting bolts. Disconnect brake pipe (or pipes) from wheel cylinder and put wheel cylinder bleeder plug cap (1) onto pipe to prevent fluid from spilling.
Installation (for non sealed type)
1. Take off bleeder plug cap from brake pipe and connect pipe (for pipes) to wheel cylinder (1) just enough to prevent fluid from leaking.
2. Tighten wheel cylinder to brake back plate (1) to specified torque.
3. Torque flare nut (or nuts) (2) of brake pipe (3) which was connected in step 1. to specification.
Tightening torque
Wheel cylinder bolt (for non sealed type) (a): 8.5 Nm (0.85 kgf-m, 6.5 ft. lbs.)
Brake pipe flare nut (b): 16 Nm (1.6 kgf-m, 12.0 ft. lbs.)
4. Install bleeder plug cap taken off from pipe back to bleeder plug.
5. For procedure hereafter, refer to steps 1. to 5. of BRAKE SHOE INSTALLATION.
NOTE: Be sure to bleed brake system.
Installation (for gasket sealed type)
1. Install gasket (2) to joint seam of wheel cylinder (1) and brake back plate. Then take off bleeder plug cap from brake pipe and connect pipe (for pipes) to wheel cylinder just enough to prevent fluid from leaking.
NOTE:
^ Be sure to check gasket (2) for deterioration or any damage before installation and replace if found defective.
2. Tighten wheel cylinder to brake back plate (1) to specified torque.
3. Torque flare nut (or nuts) (2) of brake pipe (3) which was connected in step 1 to specification.
Tightening torque
Wheel cylinder bolt (for gasket sealed type) (a): 11 Nm (1.1 kgf-m, 8.0 ft. lbs.)
Brake pipe flare nut (b): 16 Nm (1.6 kgf-m, 12.0 ft. lbs.)
4. Install bleeder plug cap taken off from pipe back to bleeder plug.
5. For procedure hereafter, refer to steps 1. to 5. of BRAKE SHOE INSTALLATION.
NOTE: Be sure to bleed brake system.
