Begin the process of replacing the park brake shoe (w/RPO NYS) when the park brake is off then the vehicle is secured on a lift system. Disassemble the tire and wheel assembly followed by cable tension relief through intermediate cable pull-down followed by cable release from the equalizer bar position. Start by taking out the rear park brake bracket bolt before detaching the park brake cable from the park brake actuator lever and extracting the Wheel Bearing which leads to shoe removal from the backing plate. To install the system first link the park brake shoe to the backing plate while reinstalling the Wheel Bearing before adjusting the park brake shoe position. The park brake cable needs to be connected to the park brake actuator lever before installing the rear park brake bracket bolt to a torque of 61 nm (45 ft. Lbs.). First install the tire and wheel assembly and then lower the vehicle before adjusting the park brake cable. Finally reattach the cable to the equalizer bar.

Get the work done by using these two key tools Brake Shoe spanner & spring remover (J 38400) and drum to Brake Shoe clearance gage (J 21177-A). Clean the rear Brake Shoe unit with denatured alcohol before removing its attached Brake Drum. Lower the brake shoes to their lowest position before taking out the adjuster assembly to relieve the retractor spring. A channel locks pair helps you withdraw the retractor spring from the secondary Brake Shoe and later detach the shoe from its connector surface. Do these steps again with the primary Brake Shoe by taking out its retractor spring too. Push the small flat-blade screwdriver into the lock tab of the park brake cable and keep it stable. Press the park brake cable forward until it detaches from the retainer but keep the park brake spring connected to the lever. Apply a small amount of high-temperature silicone grease to both matching surfaces where the rear brake shoes touch the backing plate. You should feel or hear a snap when positioning the park brake cable into the lever. Check that the retractor spring fits correctly into its bracket at the backing plate bottom before fixing the backing plate onto place. Alternate channel locks to position the retractor spring into the primary Brake Shoe followed by installing the secondary Brake Shoe onto the backing plate. Angling the retractor spring requires either channel locks or the Brake Shoe spanner & spring remover tool j 38400. Place the park brake adjusting equipment and set the rear brake shoes to the right distance using the drum to Brake Shoe clearance gage (J 21177-A).

A mechanic should start their Brake Shoe replacement procedure by eliminating the rear Brake Drum followed by using denatured alcohol to clean the rear brake shoes. The brake shoes need adjustment at their lowest position to lower the retractor spring tension before extracting the adjuster assembly. A pair of channel locks should be used to extract the retractor spring from the secondary Brake Shoe before separating the backing plate from the secondary Brake Shoe. Follow this same installation process for the primary Brake Shoe while also removing its return spring during the operation. To release the park brake cable lock use a small flat-blade screwdriver and hold it while pressing the lock tab. Next pull the park brake cable forward to unlock it from the retainer. Pull the park brake cable from the lever yet maintain attachment of the park brake return spring to the lever. Isothermal silicone grease should be applied in small amounts to all contact areas between the rear brake shoes and backing plate. A snap or clip sound must be heard when fitting the park brake cable into position to verify the correct seating. The retractor spring must be correctly installed in the retaining bracket at the backing plate bottom before mounting the backing plate. The retractor spring needs tool j 38400 to be installed into the primary Brake Shoe before placing the secondary Brake Shoe onto the backing plate. The completion of the procedure requires the tool j 22364-01 to adjust the rear brake shoes followed by reinstalling the rear Brake Drum.

Start with obtaining the essential replacement tools defined as Brake Shoe spanner & spring remover (J38400) and drum to Brake Shoe clearance gage (J21177-A). Start the process by taking out the Brake Drum from the back and cleaning brake shoes with denatured alcohol. The brakes should be adjusted to their lowest position to soften the retractor spring tension before starting the adjuster assembly removal process. Channel locks should be used to disconnect the retractor spring from the secondary Brake Shoe before separating the shoe from the backing plate. Initiate this process again for the primary Brake Shoe while you must remove the retractor spring before beginning. A small flat-bladed screwdriver can be used to press the park brake cable lock tab while you maintain its position after eliminating the return spring. Advancing the park brake cable releases it from the retainer yet maintain the return spring attached to the lever since it forms part of the Brake Shoe assembly. High-temperature silicone grease should be applied using a small amount to the points where the rear brake shoes touch the backing plate during installation. A proper seat of the Parking Brake Cable into the lever should produce either a snap sound or a click feedback. Verify that the retractor spring has a proper fit in the retaining bracket at the backing plate's bottom before mounting it onto the plate. Channel locks or j38400 Brake Shoe spanner & spring remover tools should be used for installing the retractor spring into both primary and secondary brake shoes. After installing the park brake adjusting hardware follow with shoe adjustment through use of drum to Brake Shoe clearance gage (J21177-A) before rear Brake Drum installation.

The first step to replace the park brake shoe on the 25/35 series involves tension relief from the park brake cable of the 1500hd through cable pull in front of the equalizer followed by equalizer bar removal. The park brake cable automatic adjuster must be disabled before working on the 25/35 series. Rise and stabilize the vehicle afterward detach the tire before wheel removal. The process to extract the cable from the backing plate includes spring compression by lever push, tab depression for locking release and a combined motion of pulling housing away from plate while extracting the cable through backing plate slot. The park brake cable needs removal from the lever before moving on to the rotor and rear Axle Shaft. After removing the park brake shoe return spring and park brake shoe anchor springs as well as pins separate the shoe tips from the park brake actuator to extract the complete park brake shoes and adjuster assembly. Clean all debris from park brake components using a clean shop cloth before installing the adjuster assembly onto the park brake shoes and then opening the parked shoes apart. Afterward, place the park brake shoes onto the park brake actuator. Install the park brake shoe anchor springs first followed by pins and then install the park brake shoe return spring before performing the park brake shoe adjustment. The assembly requires installation of the rear Axle Shaft and rotor while the park brake cable must connect to the lever. Use the spring compression through the lever push to slide the cable through the backing plate slot before placing the cable housing into the backing plate until locking tabs lock in position. Start by installing the wheel and tire followed by safety stand removal and lowering the vehicle along with enabling the automatic park brake cable adjuster and also for 1500hd models you should install the park brake cable to the equalizer through a process of pulling down the cable ahead of the equalizer and securing it to the equalizer bar before you adjust the cable.

The first step for replacing the park brake shoe on the 25/35 series requires the relaxation of park brake cable tension on the 1500hd through cable reduction in front of the equalizer and equalizer bar detachment and completion of the 25/35 series automatic adjuster disablement. Support the vehicle properly then take off the tire together with the wheel. The procedure for backing plate cable removal involves spring compression toward the lever while depressing locking tabs followed by extracting the cable housing through the plate opening and finally pulling out the cable from its place. Start by removing the park brake cable from the lever then the rotor along with the rear Axle Shaft. The removal process starts by taking out the park brake shoe return spring followed by the park brake shoe anchor springs and pins as well as the separation of tips from park brake actuator to extract the park brake shoes and adjuster assembly. Use a clean shop cloth to clean the park brake components before installing the adjuster assembly to the park brake shoes then spacing the tips of the shoes while fitting them onto the park brake actuator. After attaching park brake shoe anchor springs and pins one must install the park brake shoe return spring and adjust the park brake shoe. Install the rear Axle Shaft and rotor after which you can connect the park brake cable to the lever. To install the cable on the backing plate use a spring-compressing movement towards the lever followed by slotting the cable through the backing plate before pushing the cable housing until the locking tabs activate. After installing the tire and wheel use safety stands to lower the vehicle and turn on the automatic cable adjuster for all models except the 1500hd. The 1500hd requires the park brake cable installation onto the equalizer by pulling the cable down in front of the equalizer and connecting it to the equalizer bar before adjusting the park brake cable.

Place one open end of the shoe over the axle flange and rotate it until it clears the flange.
