You can Select Your Vehicle to check if 44060-8J00K fits your vehicle.

Remove the rear brake discs. Measure the thickness of the lining material on the shoes. If the lining has worn down to 1.5 mm or less, replace the shoes. Inspect the drum portion of the disc for scoring, grooves, or cracks due to heat. If any of these conditions exist or there is significant wear to the drum, the disc must be replaced. Wash off the brake parts with brake system cleaner. Follow the accompanying illustrations for the brake shoe replacement procedure: Turn the adjuster until it's at its shortest setting (the threads disappear into the adjuster). Remove the adjuster spring. Remove the adjuster. Remove the return spring. Remove the rear shoe hold-down retainer, spring, pin, and shoe. Remove the forward shoe hold-down retainer, spring, pin, and shoe. Clean the backing plate thoroughly, then lubricate the brake shoe contact areas on the plate with high-temperature grease. Clean and lubricate the adjuster. Place the forward shoe in position and install the hold-down retainer, spring, and pin. Place the rear shoe in position and install the hold-down retainer, spring, and pin. Install the return spring. Install the adjuster. Install the adjuster spring. Be sure to stay in order and read the caption under each illustration. Note: Work on one side at a time using the opposite side for reference as necessary. Install the brake disc and use two lug nuts with washers (for spacing) to hold the disc securely against the hub. Adjust the rear parking brake shoes. Install the caliper bracket and brake caliper. Be sure to tighten the bolts to the specified torque values. Install the wheel and lug nuts. Lower the vehicle and tighten the lug nuts to the specified torque. Check the parking brake for proper operation. If they are not fully operational, perform a break-in procedure. Break-in the new shoes by performing the following procedure: Set and release the parking brake a few times. Set the parking brake. Drive the vehicle to 20 miles per hour. Stop the vehicle and RELEASE THE PARKING BRAKE. Allow the parking brake shoes and disc/drum to cool for 5 minutes, then drive the vehicle normally for another two minutes. Repeat these break-in steps again if necessary, but no more than three cycles. Do not shorten the cooling period between driving cycles. Check the parking brake adjustment and adjust it again if necessary.

Jack up the rear of the vehicle and support it securely on jackstands. Remove the rear caliper and brake disc. Check the shoes for wear, damage, and contamination, replacing them if problems are found. To remove the shoes, unhook the springs and take them off, then separate the shoes from the toggle lever and adjuster. Apply a light coat of high-temperature brake lubricant to the shoe contact points on the backing plate. Installation is the reverse of the removal steps, with the spring that has one coil going at the top next to the adjuster and the spring with two coils positioned at the bottom.

Whenever the brake shoes are replaced, the return and hold-down springs should also be replaced due to the continuous heating and cooling cycle that causes them to lose tension over time, potentially leading to faster wear of the shoes. Begin by loosening the wheel lug nuts, raising the rear of the vehicle, and securely supporting it on jackstands while blocking the front wheels to prevent rolling. Remove the wheels and release the parking brake to take off the brake drums. If the shoes are worn into the drum, use a small screwdriver to lift the adjuster lever and back off the brake shoes for drum removal. If the drum is rusted to the hub, install two bolts into the threaded holes and tighten them to push the drum off. Replace all four rear brake shoes simultaneously, working on one brake assembly at a time to avoid mixing parts. Clean the brake assembly with brake system cleaner and allow it to dry, ensuring to catch any residue. Remove the hub and wheel bearing assembly, then take off the hold-down retainers and springs from the brake shoes using a brake spring tool. Disengage the front shoe from the wheel cylinder and anchor plate, then remove the lower return spring. Pull the rear shoe toward the rear of the vehicle to disengage it from the wheel cylinder, and remove the adjuster assembly, noting its orientation. Unhook the upper return spring from both shoes and detach the parking brake cable from the lever on the rear shoe before removing it. Check for leakage by peeling back the dust boots on the wheel cylinder and replace it if necessary. Clean the brake backing plate and lubricate the shoe contact points with high-temperature brake grease. Remove the retaining clip from the parking brake lever pivot pin, transfer the lever to the new shoe, and secure it with a new retaining ring. Connect the parking brake cable to the lever, then position the rear shoe on the backing plate, inserting the hold-down pin and installing the hold-down spring and retainer. Clean and lubricate the adjuster screw assembly, install it into the rear shoe, and secure the front shoe with the hold-down spring. Install the return springs and check the drum for cracks or damage before reinstalling it. Adjust the shoes so they just slip over the drum, then ensure they drag slightly before backing off the adjuster screw. Mount the wheel, install the lug nuts, lower the vehicle, and tighten the lug nuts to the specified torque. Finally, make several forward and reverse stops and operate the parking brake to adjust the brakes for satisfactory pedal action, checking the operation of the brakes carefully before driving.

When reinstalling the calipers, tighten the mounting bolts to the specified torque.
