Rear Cable

The procedure to replace a parking brake rear cable on the left side must begin with discharging the park brake while disabling the automatic adjuster mechanism. Beginning with vehicle lifting and support the technician can disconnect the left rear park brake cable at the equalizer point on intermediate park brake cable. You can remove the park brake cable from its mounting bracket through locking tab depression before unfastening the nut and bolt which secure the cable to the rear axle housing bracket for 2500 series vehicles. First disconnect the park brake cable guides from the vehicle frame and after that remove it from the actuator lever followed by removing it from the backing plate through its locking tabs. Begin by properly placing the new cable through all guides and body mounts then secure the backing plate by pressing it until locking tabs engage before linking it to the actuator lever. Install the park brake cable at the rear axle bracket then bolt and nut (2500 series) installation requires 22 Nm (16 lb ft) torque force. Routing the cable to the frame guides and attaching it to the mounting bracket will complete the installation when the tabs correctly lock into place. Use the left rear park brake cable to connect with the intermediate park brake cable equalizer followed by a vehicle lower and then activate the automatic adjuster to adjust the park brake according to need.

The first task to replace the right side parking brake rear cable requires operatives to release the brake and disable the automatic adjuster function. After vehicle support, unscrew the right rear park brake cable from the equalizer part of the intermediate park brake cable. The parking brake cable requires release from both the mounting bracket by pushing the locking tabs and the guides on the frame of the vehicle. Disassemble the bolt which anchors the rear axle clip on 2500 series vehicles and dislodge the park brake cable from its housing at the differential clip on 2500 series vehicles and the track bar clips on 1500 series models. Detach the cable from the actuator lever first before removing it both from the backing plate and the retaining bracket. The new park brake cable needs proper routing through guides and body mounts before pressing it onto the backing plate until tab locks take place followed by securing it to the actuator lever. Secure the cable on the track bar using clips which must rest between its location markups (1500 series series). The cable needs to reach the vehicle frame guides and you need to install it at the mounting bracket until the tabs secure into position. The bolt should be installed into the rear axle cable clip (2500 series) while applying torque to 22 N.m (16 lb ft) to maintain cable security while avoiding any cable damage or constraint. Connect the right rear park brake cable to the intermediate park brake cable equalizer as well as the differential clip (2500 series). To complete the procedure lower the vehicle then enable and adjust the park brake automatic adjuster.
