Clean away all dirt, crud and foreign material from around wheel cylinder. It is important that dirt be kept away from the brake line when the cylinder is disconnected.
Disconnect the inlet tube line.
Wheel cylinders are retained by two types of fasteners. One type uses a round retainer with locking clips, which attaches to the wheel cylinder on the back side of the brake backing plate. The other type simply uses two bolts, which screw into the wheel cylinder from the back side of the backing plate.
To remove the round retainer type cylinders, insert two pawls or pins into the access slots between the wheel cylinder pilot and the retainer locking tabs. Bend both tabs away simultaneously. The wheel cylinder can be removed, as the retainer is released.
To remove the cylinders, loosen and remove the bolts from the back side of the backing plate, and remove the cylinder.
To install the retainer type cylinder, position the wheel cylinder and hold it in place with a wooden block between the cylinder and axle flange. Install a new retainer clip, using a 1
", 12-point socket and socket extension. This tool will seal the retainer evenly.
On the bolt type cylinder, position the cylinder and install the bolts.
On both types of cylinders, torque the inlet type nuts evenly.
Assemble the remaining brake components. Bleed the brakes.
