Toyota 46540-20040 Shoe Assembly, Parking Brake, LH

Remove the brake disc and inspect the thickness of the lining material on the shoes; if it has worn down to 0.039 inch or less, replace the shoes. Unhook the parking brake shoe return springs from the anchor pin using a special brake spring tool for ease. Remove the shoe strut from between the shoes along with the spring assembly, then take out the front shoe hold-down spring, followed by the shoe and adjuster. Next, remove the rear shoe hold-down spring, disconnect the parking brake cable from the lever, and take out the shoe. Spread the C-washer on the parking brake lever pivot pin with a screwdriver, then remove the lever, shim, and pin, transferring these parts to the new rear shoe and crimping the C-washer to the pin with pliers. Apply a thin coat of high-temperature grease to the shoe contact surfaces of the backing plate and to the threads and sliding portion of the adjuster. Connect the parking brake cable to the lever and mount the rear shoe to the backing plate, installing the hold-down spring. Connect the tension spring to the lower ends of both shoes and install the adjuster, ensuring the tension spring and adjuster screw are arranged correctly. Position the front shoe on the plate and install the hold-down spring, then install the parking brake strut with the spring facing forward between the two shoes, followed by the shoe return springs. Install the brake disc, temporarily threading three of the wheel lug nuts onto the studs to hold it in place. Remove the hole plug from the brake disc and adjust the parking brake shoe clearance by turning the adjuster star wheel with a brake adjusting tool or screwdriver until the shoes contact the disc and it cannot be turned, then back off the adjuster eight notches and install the plug. Install the torque plate and brake caliper, ensuring the bolts are tightened to the specified torque, then install the wheel and tighten the lug nuts to the specified torque. Pull up on the parking brake handle and count the number of clicks; it should be between five and eight clicks, and if not, adjust the parking brake. To bed the shoes to the drum, drive the vehicle at approximately 30 mph on a dry, level road, pushing in on the parking brake release button and pulling up slightly on the lever with about 20 pounds of force, driving for 1/4-mile with the parking brake applied. Repeat this procedure two or three times, allowing the brakes to cool between applications.

Loosen the wheel lug nuts, raise the rear of the vehicle, and support it securely on jackstands while blocking the front wheels to prevent rolling. Release the parking brake and remove the wheel, ensuring that all four rear brake shoes are replaced simultaneously but working on one brake assembly at a time to avoid mixing parts. Clean the brake assembly with brake cleaner and allow it to dry, positioning a drain pan underneath to catch fluid and residue, avoiding the use of compressed air for dust removal. Unhook the return spring from the front brake shoe, using locking pliers to stretch the spring, and then depress the hold-down spring to remove the front shoe and unhook the anchor spring. Remove the hold-down spring and rear shoe along with the adjuster assembly, then pull the parking brake cable out of the lever and remove the adjusting lever spring. Pry apart the C-washer to separate the parking brake lever and adjuster lever from the rear shoe, then assemble these components onto the new rear shoe, crimping a new C-washer closed. Lubricate the adjuster screw with high-temperature grease, install the adjuster assembly on the rear shoe, and secure the shoe assembly against the backing plate with the hold-down spring pin. Connect the anchor spring to each shoe, mount the front shoe, and install the hold-down spring and cups. Stretch the return spring into the front shoe and check the parking brake lever. Lubricate the brake shoe contact area, pull back the parking brake cable spring, and place the cable into the parking brake lever. If the brake drum cannot be easily removed, ensure the parking brake is fully released and retract the brake shoes if necessary by removing the plug from the backing plate and adjusting the star wheel. Before reinstalling the drum, inspect it for cracks, score marks, and hard spots; if any issues are found, take it to an automotive machine shop for resurfacing. Install the brake drum on the axle flange, mount the wheel, install the lug nuts, and lower the vehicle. Make several forward and reverse stops and operate the parking brake to adjust the brakes for satisfactory pedal action, then carefully check the operation of the brakes before driving.
