Why Remove Brake Drums?

Before we jump into the how-to, let's quickly cover the why. Understanding the reasons behind this task can help you appreciate the process and the importance of proper brake maintenance. Brake drums, a crucial part of your vehicle's braking system, house the brake shoes and other components. Over time, these drums can wear down, become scored, or even develop cracks, affecting your braking performance. Removing them becomes necessary for several reasons:

Inspection and Maintenance: One of the primary reasons to remove brake drums is for inspection. You'll want to check the condition of the drum itself for wear, cracks, or damage. Similarly, you'll need to inspect the brake shoes, springs, and other internal components for wear and tear. Regular inspections can help you catch potential problems early, preventing more costly repairs down the road.
Replacing Worn Components: Like any part of your car, brake components wear out over time. Brake shoes, in particular, are designed to wear down as they provide the friction needed to stop your vehicle. When they reach their wear limit, they need to be replaced. Similarly, the drums themselves might need replacing if they're too thin or damaged. Removing the drums is essential for accessing and replacing these worn components.
Addressing Brake Problems: Sometimes, you might experience specific brake problems, such as squealing, grinding noises, or a loss of braking power. These issues can often be traced back to problems within the drum brake system. Removing the drums allows you to diagnose the problem more effectively and make the necessary repairs. This could involve cleaning, lubricating, or replacing parts.
Wheel Cylinder Replacement: The wheel cylinder is a hydraulic component that pushes the brake shoes against the drum when you apply the brakes. If a wheel cylinder fails, it can leak brake fluid and compromise your braking performance. Replacing a faulty wheel cylinder requires removing the brake drum to access it.
General Cleaning: Brake dust and debris can accumulate inside the brake drum, affecting braking performance and potentially causing noise. Removing the drums allows you to thoroughly clean the components, ensuring optimal operation. A clean brake system is a happy brake system!

In essence, removing brake drums is a fundamental part of brake maintenance and repair. It's a task that allows you to keep your braking system in top shape, ensuring your safety and the safety of others on the road. Now that we understand why it's important, let's get to the fun part: the how-to!

Chock the Wheels: Place wheel chocks behind the wheels that will remain on the ground. This adds an extra layer of safety.

2. Loosen the Lug Nuts

Use your lug wrench to loosen the lug nuts on the wheel you'll be removing. Important: Loosen them, but don't remove them completely just yet. This is easier to do while the wheel is still on the ground.

3. Jack Up the Vehicle

Consult your vehicle's owner's manual for the correct jacking points. Place the jack under the designated spot and lift the vehicle until the wheel is off the ground. Make sure the vehicle is lifted high enough to allow you to safely remove the wheel and work on the brake drum.

4. Secure the Vehicle with Jack Stands

This is the most crucial safety step! Place jack stands under the vehicle's frame near the jacking point. Ensure the jack stands are securely positioned and can support the weight of the vehicle. Slowly lower the vehicle onto the jack stands. Never work under a vehicle supported only by a jack.

5. Remove the Wheel

Now that the vehicle is safely supported, you can completely remove the lug nuts and take the wheel off. Set the wheel aside in a safe place.

6. Inspect the Brake Drum

Take a good look at the brake drum. Check for any visible signs of damage, such as cracks, excessive rust, or scoring. This will give you a clue about the condition of your braking system.

7. Remove the Brake Drum (The Tricky Part!)

This is where things can get a little challenging, especially if the drum is stuck. Here's how to tackle it:

Try Pulling it Off: Sometimes, the drum will slide right off. Try gripping it firmly with both hands and pulling straight out. If it comes off easily, great! If not, move on to the next steps.
Adjust the Brake Shoes (If Necessary): Over time, the brake shoes can wear and create a ridge inside the drum, making it difficult to remove. Locate the brake adjuster access hole on the backing plate (usually on the bottom). Use a flat-head screwdriver or a brake adjusting tool to turn the adjuster wheel and retract the brake shoes. This will give you some extra clearance.
Use Penetrating Oil: If rust is the culprit, spray penetrating oil around the center hub and around the edges of the drum where it meets the backing plate. Let it sit for at least 15-20 minutes to work its magic.
Tap the Drum with a Hammer: Gently tap the drum with a hammer (preferably a rubber mallet) around its circumference. This can help break loose any rust or corrosion. Don't hit it too hard, as you don't want to damage the drum.
Use a Brake Drum Removal Tool (Recommended): If the drum is still stuck, this tool is your best friend. Attach the puller to the drum according to the manufacturer's instructions. Tighten the center bolt of the puller, applying even pressure to the drum. This should gradually pull the drum away from the hub. If it's really stubborn, you might need to apply penetrating oil and tap the drum while using the puller.

8. Clean the Brake Components

Once you've successfully removed the brake drum, use brake cleaner to thoroughly clean the brake shoes, springs, wheel cylinder, and the inside of the drum. This will remove brake dust and debris, allowing you to inspect the components more easily.

9. Inspect the Brake Components

Now that everything is clean, carefully inspect all the components for wear, damage, or leaks. Pay close attention to the brake shoes (check the thickness of the friction material), the wheel cylinder (look for leaks), and the springs (check for cracks or damage).

10. Reassembly (If Not Replacing)

If you're not replacing any parts, you can reassemble the brake drum. Carefully slide the drum back onto the hub. If you adjusted the brake shoes earlier, you'll need to readjust them so that they have the correct clearance. Consult your vehicle's repair manual for the proper adjustment procedure.

11. Reinstall the Wheel and Lower the Vehicle

Put the wheel back on, tighten the lug nuts hand-tight, and then lower the vehicle back to the ground. Once the vehicle is on the ground, torque the lug nuts to the manufacturer's specifications using a torque wrench.

12. Test Your Brakes

After reassembling everything, it's crucial to test your brakes. Pump the brake pedal several times to ensure it feels firm. Then, take the vehicle for a slow test drive in a safe area. Check that the brakes are working properly and that there are no unusual noises or vibrations.
