1. Preparation:
* Park on a level surface and engage the parking brake firmly. This is crucial for safety.
* Secure the vehicle: Use jack stands to lift the rear of the car securely off the ground after using a jack to lift it initially. Never work under a car supported only by a jack.
* Gather your tools: You'll need a lug wrench, a wheel chock (for the opposite wheel), a hammer, a large flathead screwdriver (or a brake drum puller – recommended), and possibly a wire brush to clean rust. Penetrating oil (like PB Blaster) can be helpful.
2. Removing the Wheel:
* Loosen the lug nuts slightly before jacking up the vehicle. This prevents them from turning when the wheel is off the ground.
* Remove the wheel and set it aside safely.
3. Removing the Brake Drum:
* Inspect the brake drum: Look for a small inspection hole near the wheel studs. This might be covered by a rubber plug. If present, remove this plug. You might need to clean up some rust around this area.
* Clean the area around the drum: Remove any loose dirt, debris, or rust. This will improve your grip.
* Try to remove the drum by hand: Sometimes, they'll just slide right off after some gentle rocking and pulling. If this fails, you'll need more force.
* Use a flathead screwdriver: Gently insert the screwdriver between the drum and the backing plate, being careful not to damage the surface of the drum or the backing plate. Pry the drum carefully, working your way around its circumference. This may require considerable effort.
* Use a brake drum puller (recommended): This tool is specifically designed to remove stubborn brake drums without damage. Follow the manufacturer's instructions for its use.
* If the drum is seized: If the drum is extremely difficult to remove, penetrating oil applied around the edge of the drum may help loosen it. Let it sit for a while to work before trying again. Be patient and avoid excessive force that could cause damage.
4. After Removing the Drum:
* Inspect the brake shoes and components: Check for wear and tear, and replace any worn or damaged parts.
* Be prepared for debris: Expect grease, dirt, and possibly rust to come out with the brake drum.
Important Considerations:
* Rust and corrosion: On older vehicles, rust and corrosion can make drum removal difficult. Penetrating oil is your friend here.
* Drum puller: While a flathead screwdriver can work, a drum puller makes the job much easier and safer. It prevents damage to the drum and backing plate.
* Brake adjustment: After replacing the shoes (if needed), you may need to adjust the brake shoes. Consult your vehicle's repair manual or a reputable automotive resource for the correct procedure.
This is a general guide. Always refer to your vehicle's repair manual for specific instructions and torque specifications. If you are uncomfortable performing this task, it's best to take your vehicle to a qualified mechanic. Improperly performed brake work can be dangerous.
