Wheel Cylinder

Before replacing the Wheel Cylinder you need to raise the vehicle and position support stands under it. Take off the tire and wheel unit first and then take off the Brake Drum. Take out dirt and contamination from the area surrounding the brake hose banjo bolt and Wheel Cylinder link. Place the lower Control Arm assembly over a jack stand to protect it during this work. You can replace the Wheel Cylinder when you remove both the upper Control Arm Bolt and wheel speed sensor connector while positioning abs-equipped systems away from the brake hose. To avoid contamination you must cap the exposed brake hose after removing its banjo bolt and gaskets made from copper. Detach the Wheel Cylinder mounting screws from each end of the Wheel Cylinder. The j 38400 Brake Shoe spanner and spring remover tool allows you to open the brake shoes while you remove the Wheel Cylinder from its position on the Brake Backing Plate. Position the brake Wheel Cylinder on the backing plate using j38400 and tighten the two mounting bolts to 10 nm. Install new copper brake hose gaskets along the banjo bolt and Wheel Cylinder then thread the banjo bolt onto the brake hose end and tighten it to 37 ft. Lbs of torque. When abs exists on the vehicle, join the wheel speed sensor port. Then add the upper Control Arm Bolt and nut before torquing the nut to 180 nm (133 foot pounds). Put in the Brake Drum then take the jack stand off from the lower Control Arm assembly while also performing brake fluid bleeding and putting on the wheel and tire assembly before lowering the vehicle and testing the rear alignment.
