Parking Brake Shoes

Start replacing the park Brake Shoe by rescinding the park brake then lifting the vehicle while ensuring that the brake remains off. After wheel removal the brake caliper combined with bracket must transfer to the empty wheel position without disassembling components. The first step involves removing the brake caliper along with its bracket as well as the brake rotor. Start by detaching the park brake cable from the lever and then slide the park Brake Shoe down from the hold down spring to disengage it before lifting it away to slide off the actuation mechanism . Use a clean towel to wipe off debris along with dust from all park brake components while these components sit on top of the axle flange. Adjust the screw adjustment until it reaches the extreme end of the notched nut before rotating it one-quarter turn counterclockwise to achieve parallel orientation of the slots relative to the backing plate. Dampen the rear backing plate with denatured alcohol followed by airflow from non-lubricated filtered air until dry. A new park Brake Shoe should be positioned over the axle flange while it receives placement on the actuation mechanism. Push the lower shoe away from the backing plate before lowering it down above the hold down spring and set the low end against the plate for a final upward slide underneath the spring. The shoe assembly must be placed in the middle of the backing plate so both actuation mechanism slots align with the tips. The park brake manual operation requires observation of the actuation mechanism when the technician moves the park brake actuator lever. The park brake cable should be connected to the park brake lever while adjusting the park Brake Shoe and reinstalling the brake rotor alongside the brake caliper and mounting bracket and tire and wheel. Finally, lower the vehicle.

Start by releasing the park brake if engaged along with raising the vehicle. Remove the wheel and tire. Brake caliper units should be moved to the side after securing them in position while leaving the mounting bracket in place. After removing the brake caliper in combination with its bracket the next step involves removing the brake rotor. Begin the shoe replacement by detaching the park brake cable from the lever after which you must lower the shoe to disconnect it from springs. Then lift the shoe to clear the backing plate and move on with the actuation mechanism separation. Apply a clean towel to wipe away particles and dust from all park brake components that are located over the axle flange. Complete the adjustment screw home position within the notched adjustment nut before executing a 1/4 turn backward adjustment while checking the slots from adjusting screw and tappet maintain parallel alignment with the backing plate face. Apply non-lubricated filtered air to ensure the rear backing plate achieves complete dryness after cleaning it with denatured alcohol. Start by putting the new park Brake Shoe onto the axle flange followed by its positioning onto the actuation mechanism. The back end of the shoe needs to be away from the backing plate as you push the shoe downward over the hold down spring before placing it against the backing plate followed by sliding the shoe upward under the hold down spring. The shoe assembly must be placed in the center of the backing plate while its tips need to sit in the slots of the actuation mechanism. Check the park brake manually by moving the actuator lever which will trigger the park brake mechanism. The brake rotor receives installation after replacing the park brake cable onto the park brake lever and performing Brake Shoe adjustment. During the installation process reinstall the brake caliper then mounting bracket before replacing the tire and wheel and finally lowering the vehicle.

The process of replacing the park Brake Shoe begins by releasing the brake then lifting the vehicle. Switch off the park brake while raising the vehicle for work on the brakes. Remove the tire and wheel first. Then detach the brake caliper along with bracket but keep them together. Support and position them to one side. The first step involves rotor removal together with disconnection of the park brake cable from the park brake lever. The park Brake Shoe requires you to move it downward until it breaks free from the hold down spring before elevating and removing it away from the back plate to slide off from the actuation mechanism. Clean park brake components at the axle flange with a clean towel after pulling out the shoe over the flange. Set the adjustment screw at full home position within the notched adjustment nut before rotating it 1/4 turn. Ensure that both the screw slot and tappet slot remain aligned with the backing plate surface. Detergent alcohol cleans the rear backing plate before its drying happens through ungreased filtered air supply. The installation of new park brake shoes begins with placing one over the axle flange followed by positioning it onto the actuation mechanism. Pass the lower shoe end past the hold down spring towards the backing plate before resting it at the backing plate position. Push the shoe by its upper section beneath the hold down spring and confirm the shoe sits in the central position on the backing plate between the actuation mechanism slots. Operation of the park brake system must be tested by hand through observation of the actuation mechanism after moving the actuator lever. Restore the park brake cable to its connection point on the park brake lever while modifying the park Brake Shoe position. After that, add back the brake rotor followed by the brake caliper and mounting bracket. Lower the vehicle and then complete installation of the tire with its wheel.

After verifying the parking brake application status you should free it and elevate the vehicle before proceeding. Remove the wheel and tire. It is unnecessary to separate brake caliper and mounting bracket components; instead simply position them to the vehicle side before securing them in this position. Separate the brake rotor followed by disconnecting the park brake cable from its lever on the brake. Pull the park Brake Shoe down until it frees from the hold down spring before pulling it away from the backing plate and sliding it out of the actuation mechanism . Take the shoe out from its position on the axle flange after removing it from the vehicle. Clean debris and dust from the park brake components with a clean towel. Adjust the screw until it stops at the adjustment nut notches and then reverse it 1/4 turn to maintain parallel alignment of slot openings between adjusting screw and tappet relative to the backing plate face. Wipe the backing plate rear surface with denatured alcohol before using filtered non-lubricated air to dry it. When installing the new park Brake Shoe position it first over the axle flange then on the actuation mechanism. Using precaution slither the lower shoe end down from the hold down spring while keeping it away from the backing plate before securing it against the plate surface. Guide the shoe up and underneath the hold down spring so that both tips rest properly inside the actuation mechanism slots when the assembly reaches the central position on the backing plate. Rule out brake malfunctions by operating the park brake actuator lever to watch the mechanism work. Finish the installation by connecting the park brake cable to the lever, readjusting the park Brake Shoe before you put on the rotor and caliper along with its bracket. Proceed to install the tire and wheel before lowering the vehicle.

Start by freeing the applied park brake and then lift the vehicle. Remove the wheel and tire. The brake caliper along with the mounting bracket remain together during installation by moving them out of the way before securing them on the side. The maintenance starts with removing the brake caliper and bracket (part number: Rear Brake Caliper Bracket Replacement). Afterward the brake rotor requires removal. The park brake cable must detach from its lever so you can pull down the park brake shoe (part number: 2) to let it slip off its hold down spring (part number: 3). You should first lift the shoe away from the backing plate and move it off the actuation mechanism (part number: 1) before removing the shoe around the axle flange and from the vehicle. Follow the procedure of cleaning park brake components with a clean towel, adjust the screw to the notched position before moving it 1/4 turn off home. After making the slots equal on the adjusting screw and tappet to run parallel with the backing plate face, users must clean the rear backing plate surface with denatured alcohol which must then be wiped dry by using filtered non-lubricated air. New shoe part number 2 should go over the axle flange before being set onto the actuation mechanism during installation. Guide the lower shoe end away from the backing plate before sliding it downward onto the top of the hold down spring (part number: 3) while placing the end against the backing plate. Position the shoe installation so its central location on the backing plate includes both tips which fit into the slots of the actuation mechanism (part number: 1). Examine the park brake system functionality by pulling the park brake actuator lever which should activate the mechanism. You must install the park brake cable to the park brake lever before making adjustments to the park brake shoe according to the park brake adjustment guidelines followed by brake rotor installation together with the brake caliper and mounting bracket based on the rear brake caliper bracket replacement instructions. Complete the process by installing the tire along with the wheel before lowering the vehicle.

The replacement process starts by releasing the park brake followed by vehicle elevation before performing the operation. Before replacing the wheel and tire proceed by moving the brake caliper with bracket to one side but maintain their connected state. The next step requires you to remove the brake rotor along with the removal of the park brake cable running into the park brake lever. The technician should lower the park Brake Shoe to disconnect it from the hold down spring before pulling it off the actuation mechanism and away from the backing plate. Brush away dirt and debris that accumulated on the park brake components using a clean piece of fabric before installing the shoe on the axle flange. Adjust the screw adjustment nut to its maximum position while keeping the screw alignment parallel to the backing plate face and then alter screw position by 1/4 turn. The rear backing plate requires cleaning with denatured alcohol before drying it through non-lubricated filtered air. Before assembly lay a new park Brake Shoe on the axle flange before adding it onto the actuation mechanism. When keeping the shoe lower end away from the backing plate you can slide it downward over the top of the hold down spring before setting the lower end against the backing plate. After placing the shoe between the actuation mechanism slots check it stands central on the backing plate while under the hold down spring . The actuation mechanism of the park brake should be reviewed manually by operating the park brake actuator lever then checking the mechanism function. The park brake cable installation to park brake lever should be followed by park Brake Shoe adjustment before installing brake rotor and brake caliper with mounting bracket. Complete the procedure by reinstalling the tire and wheel after lowering the vehicle.
