Safety first:
Ensure that the vehicle is safely lifted and supported on jack stands.
Use appropriate safety gear, such as gloves and safety glasses.
Remove the wheel:
Loosen the lug nuts before lifting the vehicle.
Lift the vehicle using a jack and secure it on jack stands.
Remove the lug nuts and take off the wheel.
Access the brake drum:
Locate the brake drum on the braking system. You may need to remove a rubber plug or access panel to reach the brake assembly.
Release tension on the brake shoes:
If there is a parking brake cable, release the tension by locating the adjuster wheel or nut and turning it to retract the brake shoes.
Remove the drum:
Once the tension is released, the brake drum can be removed. If it's stuck, tap it gently with a rubber mallet or use a brake drum puller.
Inspect the brake components:
Check the brake drum for wear, scoring, or cracks. Replace if necessary.
Inspect the brake shoes, springs, and other hardware for signs of damage or excessive wear.
Remove the old brake pads:
Unhook the springs and retaining clips that hold the brake shoes in place.
Slide the old brake shoes and the return springs off the brake system.
Prepare the new brake pads:
Lubricate the contact points of the brake shoes with high-temperature brake grease.
Ensure the new brake shoes are of the correct size and type for your vehicle.
Install the new brake pads:
Slide the new brake shoes into position.
Reattach the springs and retaining clips.
Adjust the brake shoes:
Adjust the brake shoes to the proper clearance using the adjuster wheel or nut.
Ensure the shoes are centered within the drum.
Reinstall the brake drum:
Slide the brake drum back onto the wheel hub.
Rotate the drum to ensure it spins freely without any interference.
Reinstall the wheel:
Put the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts with a torque wrench to the manufacturer's specifications.
Test the brakes:
Pump the brake pedal to build up brake pressure.
Test the brakes at low speeds in a safe and open area to ensure they are functioning correctly.
