Brake Shoes, Rear

Vehicle elevation and tire removal lead to the replacement of brake shoes. Before taking off the Brake Drum make a mark on the relationship between Brake Drum and axle. The procedure begins by uninstalling the Brake Shoe return springs alongside the Brake Shoe guide and hold down springs and hold down pins. Following the actuator lever removal proceed to remove its pivot and lever return spring then move to remove parking brake strut and parking brake lever. The installation starts by extracting both brake shoes and their corresponding adjusting screw assembly with its spring. All components must undergo examination for heat-discolored or stressed areas because aged parts need replacement. You need to inspect the Wheel Cylinder for leakiness and get a new one if needed and visually examine the Brake Drum for scoring and quality control measurements. When installing the components apply high temperature silicone lubricant to the Brake Shoe backing plate and adjusting screw threads and socket and socket face at a thin level before confirming that right and left adjusting screws do not get mixed up. Install the brake shoes by attaching the adjusting screw assembly together with the spring while keeping all coil springs away from the adjusting screw. Set up the brake shoes on the backing plate while also installing the parking brake lever and strut spring before finishing with the parking brake strut. Proceed with installing the actuator lever followed by its pivot then the actuator lever return spring followed by the hold down pins followed by the hold down springs followed by the Brake Shoe guide followed by the Brake Shoe return springs. To complete the installation first align the Brake Drum according to the disassembly marks and reattach the tire and wheel assembly and adjust the brakes before lowering the vehicle.

Start by disengaging the park brake when present before raising the vehicle and removing the tire along with the wheel. The Brake Drum removal exposes the hardware for cleaning with denatured alcohol before employees dry parts with non-lubricated filtered compressed air. Start by removing brake adjusting hardware followed by park brake hardware components before extracting the rear brake shoes. Implementation requires applying high temperature silicone lubricant on the Brake Shoe backing plate before you install the park brake hardware and proceed to lubricate the adjuster screw before fitting the brake adjusting hardware. You should adjust both the rear brake and drum before reinstalling the Brake Drum while performing another rear brake adjustment. The last step concludes with the installation of the tire and wheel and lowering the vehicle.

The first step to replace parking brake shoes includes releasing the park brake if engaged then raising the vehicle before wheel and tire removal. The removal process begins with detaching the park brake cable off the park brake lever without disconnecting the brake caliper and mounting bracket. Secure these components next to each other after moving them away from the original placement. Move on to removing the combination of rear brake caliper and bracket assembly after which you can eliminate the rear brake rotor. You should use denatured alcohol to clean the park brake shoe assembly before drying it with non-lubricated filtered compressed air. The disengagement of the park brake shoe from the hold down spring is achieved by sliding it downward followed by lifting it away from the backing plate before the actuation mechanism can be accessed. Pull both sections of the shoe first from the axle flange then from the vehicle. Start with the adjustment screw in the fully home position of the notched adjustment nut before counter-turning it by 1/4 turn with the slots in both components parallel to the backing plate surface. Use non-lubricated filtered air to clean and dry both alcohol-treated dirt from the rear backing plate surface. A new park brake shoe should be positioned on the axle flange before installation on the actuation mechanism. Position the lower end of the shoe away from the backing plate before letting it drop onto the hold down spring and resting it against the plate. The shoe must be moved upward and underneath the hold down spring while being positioned in the center of the backing plate and both tips settled into the slots of the actuation mechanism . The shoe assembly positioning should be checked while a manual operation checks if the park brake functions correctly through movement of the park brake actuator lever. Return the park brake cable to its place on the park brake lever after checking the brake shoe position then put back the rear brake rotor and brake caliper bracket together with the wheel and tire before lowering the vehicle.

Start shoe replacement by properly supporting the vehicle while it is in a raised position. Begin the replacement process by removing the wheel together with its tire followed by caliper removal with the rotor. The park brake shoe assembly disengages from the hold down spring after sliding it towards the spring. After disengagement remove the shoe from the actuation mechanism. Clear all debris and dust off the park brake pieces by using a clean towel. Adjust the screw to its complete range in the nut's notches before backing it 1/4 turn while making sure the slots of both components face straight toward the backing plate. Place the new inner shoe on the actuation mechanism by attaching it to the hold down spring. Technicians should inspect the shoe assembly placement on the backing plate to confirm central alignment and slot tip placement. After doing this check manually activate the park brake for normal function and adjust the park brake shoe if needed. Insert the caliper then the rotor and tire and wheel before lowering the vehicle.

Start Brake Shoe replacement by using safety stands to support the vehicle and then taking off the tire and wheel assembly. Record the location of the drum relative to the hub before taking off the Brake Drum from the axle. Start by handling brake dust carefully and then remove the Brake Shoe return springs along with Brake Shoe guide and actuator link and two hold down springs followed by two hold down pins after which you need to remove actuator lever and actuator lever pivot and actuator lever return spring and park brake strut and strut spring and park brake lever and brake shoes. Examine all Brake Shoe parts after removing the adjusting screw assembly along with its spring to check for heat or stress discoloration while replacing any damaged components. The brake Wheel Cylinder should be checked for leaks and the Brake Drum needs inspection to determine finding scoring and machining specifications. Installation requires application of gm p/n 1052196 or equivalent lubricant to the Brake Shoe backing plate alongside adjusting screw threads, socket and socket face with a minimum amount while avoiding swapping right and left adjusting screws. Hardware installation of brake shoes should include fitting the adjusting screw assembly along with the adjusting screw spring while ensuring the coils stay separate from the adjusting screw. Brake shoes must be mounted on the backing plate and users need to install the park brake lever then the strut spring before adding the park brake strut and actuator lever along with lever pivot and actuator lever return spring followed by two hold down pins and two hold down springs before the addition of Brake Shoe guide and the actuator link and Brake Shoe return springs. The Brake Drum installation requires aligning it according to disassembly marks before reattaching the tire and wheel assembly and performing brake adjustments followed by safety stand removal to lower the vehicle.

This vehicle requires gm replacement brake lining material because it controls brake balance and stopping distance which will alter if any materials outside gm standards are used. Begin the Brake Shoe removal procedure by securing the vehicle with safety stands and afterward remove the tire and wheel assembly. Note down any relationships between the axle hub and Brake Drum before you begin wearing protective gear against brake dust. Begin by disconnecting the Brake Drum from the axle before removing the Brake Shoe return springs followed by the Brake Shoe guide and actuator link alongside two hold down springs and pins, then complete with removal of the actuator lever, pivot, return spring and park brake strut, strut spring and lever. Separate the brake shoes from all components of the adjusting screw assembly with its spring. A careful examination of all components must be conducted to detect heat or stress-based discoloration and players of any worn parts. Evaluate the Wheel Cylinder for leaks as well as check the Brake Drum for wear-related scoring and fabrication limits. The installation requires application of gm p/n 1052196 or equivalent lubricant on all surfaces of the Brake Shoe backing plate and adjusting screw components and their threaded contact points and socket framework. Both adjusting screws must remain separate and non-interchangeable. Place the brake shoes adjusting screw assembly and spring onto the brake shoes yet keep the coils away from the adjusting screw. The installation procedure requires the brake shoes to be placed on the backing plate before adding the park brake lever and strut spring then park brake strut followed by the actuator lever with its lever pivot and actuator lever return spring and then two hold down pins accompanied by two hold down springs followed by the Brake Shoe guide and actuator link and Brake Shoe return springs. The last steps include Brake Drum installation while following disassembly marks then reinstalling the tire together with the wheel assembly followed by brake adjustment and removal of safety stands to lower the vehicle.

A vehicle must be raised followed by eliminating the tire and wheel assembly as the first step to replace brake shoes. Drawing marks on the relation between Brake Drum and axle should come before Brake Drum removal. You must detach the Brake Shoe return springs and Brake Shoe guide as well as the hold down springs and hold down pins in the next step. Start by removing the actuator lever pivot along with the lever return spring and parking brake strut and strut spring and parking brake lever. After removing the brake shoes users should extract both adjusting screw assembly pieces with their respective springs. Check all components for discoloration indicating heat damage or material distress and change out all markedly worn parts. Look for leaks in the Wheel Cylinder and perform maintenance or buy a new one when needed before examining the Brake Drum for signs of wear and machine precision. Apply high temperature silicone lubricant to the Brake Shoe backing plate and adjusting screw threads and socket and socket face before installing though avoid mixing right and left adjusting screws. Put the brake shoes and adjusting screw assembly together while keeping the coils a sufficient distance from the adjusting screw. Fasten brake shoes to backing plate yet conduct installation of parking brake lever and strut spring alongside parking brake strut. Begin with the actuator lever and its pivot followed by the actuator lever return spring along with hold down pins and hold down springs and Brake Shoe guide and Brake Shoe return springs. During reinstallation begin with the Brake Drum placement then line it up with the previous installation marks before putting the tire back and adjusting the brakes and lowering the vehicle.

The use of gm replacement brake lining material during Brake Shoe service and repair is essential to maintain proper front and rear brake performance balance because different brake lining materials affect brake balance. The first step involves lifting the vehicle before taking off the tire assembly and wheel components. During this point label the Brake Drum's relation to the axle before unfastening the Brake Drum. Before installation begin with the removal sequence starting from Brake Shoe return springs after which come Brake Shoe guide followed by hold down springs and hold down pins before moving to actuator lever and its pivot and then lever return spring next to parking brake strut and strut spring then parking brake lever and finally brake shoes. Remove the brake shoes' adjusting screw assembly together with the adjusting screw spring before carefully inspecting all parts for discoloration or stress-induced signs. Replace any damaged components and verify the Wheel Cylinder and determine if overhauling or replacement is needed because of leakage. View the Brake Drum for any scoring issues or checking if it meets manufacturing accuracy standards. The installation requires Brake Shoe backing plate and adjusting screw threads, socket, and socket face to receive white lithium grease treatment before installing proper right and left adjusting screws. After applying white lithium grease or equivalent to the brake shoes backing plate along with adjusting screw threads, socket, and socket face, install the adjusting screw assembly followed by the adjusting screw spring onto the brake shoes while making sure the adjusting screw remains free from coil contact. Next, install the brake shoes onto the backing plate followed by the parking brake lever, strut spring, and parking brake strut. Afterward install the actuator lever, lever pivot, actuator lever return spring and hold down pins with hold down springs, Brake Shoe guide and Brake Shoe return springs as next steps. Begin by installing the Brake Drum according to the marks set during disassembly while reattaching the tire assembly followed by brake adjustment before lowering the vehicle.
