- Pliers: For gripping and manipulating parts.
- Hammer: For tapping and loosening components.
- Penetrating Oil (optional): To help loosen rusted parts.
- Wire Brush: For cleaning components.
- Torque Wrench: To tighten lug nuts to the manufacturer’s specifications.
Required Materials
- New Brake Shoes: Ensure they are the correct size and type for your vehicle.

Step-by-Step Guide to Replacing Rear Brake Shoes
Now that you have your tools and materials ready, let’s get started. Follow these steps carefully to replace your rear brake shoes:
- Loosen the Lug Nuts: Before jacking up the vehicle, use the lug wrench to loosen the lug nuts on the rear wheel you’re working on. Don’t remove them completely at this stage.
- Jack Up the Vehicle: Position the jack under the vehicle’s frame near the rear wheel you’re working on. Raise the vehicle until the tire is off the ground.
- Secure with Jack Stands: Place jack stands under the vehicle’s frame, ensuring they are securely positioned. Lower the vehicle onto the jack stands.
- Remove the Wheel: Completely remove the lug nuts and pull the wheel off the hub.
- Remove the Brake Drum: The brake drum should pull straight off. If it’s stuck, tap around the drum with a hammer. If it’s still stuck, there’s likely a lip worn into the drum from the brake shoes. Use the brake spoon to retract the adjuster. If the drum is severely rusted, you might need penetrating oil.
- Inspect the Brake Components: Before removing the old brake shoes, take a moment to examine the entire brake assembly. Note the positions of the springs, clips, and other hardware. This will help you during reassembly.
- Remove the Brake Shoes: Use the brake spring tool to remove the springs that hold the brake shoes in place. There are usually several springs. After removing the springs, the shoes should come off.
- Remove the Hardware: Remove the old hardware, including the springs, clips, and any other components.
- Clean the Backing Plate: Use a wire brush and brake cleaner to thoroughly clean the backing plate, removing any rust, dirt, or debris.
- Install the New Hardware: Install the new hardware kit, including the springs, clips, and any other components. Refer to your vehicle’s repair manual or a diagram for the correct placement.
- Install the New Brake Shoes: Position the new brake shoes on the backing plate, making sure they align correctly with the wheel cylinder and the adjuster.
- Install the Springs: Use the brake spring tool to install the springs that hold the brake shoes in place. This can be a bit tricky, so take your time.
- Lubricate Contact Points: Apply a small amount of anti-seize lubricant to the contact points where the brake shoes touch the backing plate. This will prevent corrosion and ensure smooth movement.
- Install the Brake Drum: Carefully slide the brake drum back onto the hub. Make sure it fits properly.
- Adjust the Brake Shoes: Use the brake spoon or adjusting tool to adjust the brake shoes. Turn the adjuster until the shoes lightly contact the drum. Then back off a few clicks until there is minimal drag when you rotate the drum by hand.
- Install the Wheel: Put the wheel back on the hub and tighten the lug nuts by hand.
- Lower the Vehicle: Use the jack to raise the vehicle slightly, remove the jack stands, and then lower the vehicle to the ground.
- Torque the Lug Nuts: Use a torque wrench to tighten the lug nuts to the manufacturer’s specifications. This is crucial for safety.
- Test the Brakes: Before driving, test the brakes in a safe area to ensure they are functioning correctly. Pump the brake pedal several times to seat the brake shoes.
Important Considerations and Tips
Replacing brake shoes can be a straightforward process, but there are some important considerations and tips that can make the job easier and more successful. (See Also: Why Does Travis Kelce Wear Yellow Shoes )
Brake Shoe Wear and Inspection
Regularly inspect your brake shoes for wear. Look for signs of uneven wear, cracking, or damage. The brake shoes should be replaced if they are worn down to the minimum thickness specified by the manufacturer. Inspect the brake drums for any scoring or damage. If the drums are damaged, they may need to be resurfaced or replaced.
Brake Fluid and the Master Cylinder
When you compress the wheel cylinder pistons to install the new brake shoes, you are pushing brake fluid back into the brake lines. Check the brake fluid level in the master cylinder reservoir. If the fluid level is too high, some fluid may overflow. If the fluid is dirty or old, consider flushing and replacing the brake fluid.
Cleaning and Lubrication
Proper cleaning and lubrication are essential for the longevity and performance of your brake system. Clean all components with brake cleaner to remove dirt, grease, and debris. Lubricate the contact points of the brake shoes with anti-seize lubricant to prevent corrosion and ensure smooth movement. Be careful not to get any lubricant on the brake shoe friction surfaces.
Brake Adjustments
Proper brake adjustments are critical for optimal braking performance. After installing the new brake shoes, adjust them to ensure they are close to the brake drum without dragging. This can be done using the brake spoon or adjusting tool. Adjust the brakes until there is a slight drag when you rotate the drum by hand. Check your work by taking a test drive in a safe area.

Common Mistakes to Avoid
There are some common mistakes people make when replacing brake shoes. Avoiding these mistakes can save you time, frustration, and potential safety hazards. Here’s a list of things to keep in mind:
- Forgetting to Chock the Wheels: Always chock the wheels to prevent the vehicle from rolling.
- Not Using Jack Stands: Never work under a vehicle supported only by a jack.
- Installing Brake Shoes Incorrectly: Double-check the orientation of the brake shoes and springs before installation. Refer to a diagram.
- Not Cleaning the Backing Plate: Thoroughly clean the backing plate to remove rust and debris.
- Over-Tightening Lug Nuts: Always use a torque wrench to tighten lug nuts to the manufacturer’s specifications.
- Not Testing the Brakes: Test the brakes in a safe area before driving on public roads.
Here are some frequently asked questions about replacing rear brake shoes.
How Often Should I Replace My Rear Brake Shoes?
The lifespan of brake shoes varies depending on driving conditions and habits. However, most brake shoes last between 25,000 and 50,000 miles. It’s recommended to inspect your brake shoes every time you have your tires rotated or at least once a year. If you notice any signs of wear, such as squealing, grinding, or reduced braking performance, have them inspected immediately.
Can I Just Replace the Brake Shoes on One Side?
It is generally recommended to replace the brake shoes on both sides of the axle at the same time, even if only one side is worn. This ensures even braking performance and prevents the vehicle from pulling to one side when braking. Replacing both sides also helps to maintain balance and extends the life of your brake system.
What Happens If I Don’t Replace My Brake Shoes When They’re Worn?
If you delay replacing worn brake shoes, you risk several problems. First, you’ll experience reduced braking performance, making it harder to stop your vehicle quickly and safely. Second, the metal backing of the brake shoes will start to grind against the brake drum, damaging the drum and potentially requiring more expensive repairs. In severe cases, you could lose braking ability altogether, which is extremely dangerous.
Conclusion
Replacing rear brake shoes is a manageable task that can save you money and keep your vehicle’s braking system in top condition. By following these steps, taking the necessary safety precautions, and using the right tools, you can confidently replace your rear brake shoes at home. Remember to prioritize safety and double-check your work. Regular maintenance, including brake shoe replacement, is critical for safe driving.
