Jeep 68003778AA Disc Brake Caliper

If caliper replacement is needed, consider all options. New and rebuilt calipers are available for exchange. Always replace in pairs. To remove, drain fluid from the reservoir, loosen lug nuts, raise the vehicle, and remove wheels. Push piston back into caliper bore. Disconnect brake hose, remove banjo bolt, and catch any fluid. Unscrew mounting bolts and detach caliper. For installation, inspect and replace mounting bolts if needed, clean, lubricate, and tighten them. Install brake hose and banjo bolt with new washers, and tighten. Bleed brakes, install wheels, lower vehicle. Depress brake pedal to align pads with disc, and check operation before driving.

Before starting the process If an overhaul of some kind is needed, typically in reaction to fluid leakage, consider all your choices. The task is relatively easy, as new and factory rebuilt calipers are offered on an exchange basis. If the decision is made to rebuild the calipers, make sure that a rebuild kit is available before and always rebuild calipers in sets. When it is time to remove the calipers, take off the cap from the brake fluid reservoir and evacuate two-third of the defective brake fluid into a dumping bin. For other cars, loosen the wheel lug nuts, lift the car and place it on jackstands after which you can remove the wheels. Drop the piston in the caliper bore; when operating models from 1987 to 1995 and those from 2007 onwards, use a large C-Clamp, while the 1997 to 2006 models may require a screwdriver applied on the piston back. Remove the brake hose from the caliper by unscrewing the banjo bolt and holding a piece of rag to collect any dripping fluid and also putting a polythene bag around the brake hose to minimize the chance of the fluid dripping. Such situations should not call for the removal of the brake hose in as much as one may need to access other parts. Remove the two caliper pins or mounting bolts to allow the detachment of the caliper from the torque plate or mounting bracket. Locate the caliper pins, and the mounting bolts and check for signs of excessive corrosion; if the corrosion is severe then these components must be changed. Purge the mounting area of the caliper and the anchor plate or mounting bracket before installing the caliper. Refit the brake hose, and banjo bolt, with new copper crush washers fitted to both sides of the banjo fitting, tightening to supply torque. If the brake hose was disconnected, then go bleeding the brakes. Finally, the final procedure is the fixing of the wheels, then lowering the car and the final step is the tightening of the wheel lug nuts to the recommended torque. Following this it is advisable to depress the brake pedal several times with considerable force in order to ensure that the brake pads have engaged with the brake disc and then to test the operation of the brakes before maneuvering in traffic.
