MGB Rear Brake Drum Removal Steps for Efficient Brake Maintenance

How to Remove the Rear Brake Drum on an MGB

The MGB is a classic British sports car known for its sleek design and enjoyable driving experience. However, like any vehicle, it requires maintenance and occasional repairs. One common task that MGB owners may encounter is the removal of the rear brake drum. Whether you're looking to replace brake shoes, inspect the brake system, or perform other maintenance, understanding how to properly remove the rear drum is essential. This guide will walk you through the process step-by-step.

Tools and Materials Needed

Before starting, gather the necessary tools and materials - Jack and jack stands - Wheel chocks - Lug wrench - Brake drum puller (if necessary) - Screwdriver - Torque wrench - Brake cleaner - Old rags or shop towels

Safety First

Safety is paramount when performing vehicle maintenance. Make sure to work on a flat, stable surface and apply the parking brake. Place wheel chocks around the front wheels to prevent any movement. Ensure that the area is well-ventilated, especially if using brake cleaner.

Step 1 Remove the Wheel

Begin by loosening the lug nuts on the rear wheel using a lug wrench. It’s easier to do this while the wheel is still on the ground. Once you’ve loosened them, use a jack to lift the rear of the MGB. Secure the vehicle with jack stands to ensure stability. After it’s safely supported, remove the lug nuts entirely and take off the wheel, exposing the drum.

Step 2 Inspect the Drum

With the wheel removed, visually inspect the brake drum for any signs of damage, such as cracks or excessive wear. If you notice any issues, it may be wise to replace the drum. If everything looks good, you can proceed with removal.

Step 3 Remove the Brake Drum

The brake drum may be secured by a retaining screw. If so, use a screwdriver to remove this screw before attempting to take off the drum. If the drum is stuck due to rust or wear, you might need a brake drum puller. Attach the puller to the drum according to the manufacturer’s instructions, and gradually apply pressure until the drum loosens.

If you’re struggling, gently tapping around the drum with a hammer can help break any corrosion bonds. Be cautious not to damage surrounding components.

Step 4 Inspect Brake Components

Once the drum is off, take the opportunity to inspect the brake shoes, wheel cylinder, and other components. Look for any signs of wear or leakage. If the brake shoes are worn, this is an excellent time to replace them. Clean any dust or debris using brake cleaner and an old rag.

Step 5 Reinstall or Replace

If you are simply inspecting or replacing the shoes, follow the reverse procedure for reinstallation. Make sure to align everything correctly and reattach the drum securely. If you've replaced any components, ensure they are correctly seated and torqued to the manufacturer’s specifications.

Step 6 Reattach the Wheel

After ensuring all components are in their proper place, it’s time to reattach the wheel. Place the wheel back on the hub, hand-tighten the lug nuts, and then lower the vehicle. Once on the ground, use the torque wrench to tighten the lug nuts to the correct specifications.

Final Checks

Before taking your MGB for a test drive, pump the brake pedal a few times to ensure the brake shoes are properly seated against the drum. Finally, check for any unusual noises or issues during a short drive around the block.

Conclusion

Removing and servicing the rear brake drum on your MGB can seem daunting, but with a little patience and the right tools, it’s a manageable task. Regular maintenance of your brake system is crucial for safe driving, so don’t hesitate to seek professional help if you’re uncertain at any point in the process. Enjoy your classic ride and the pride of maintaining it yourself!
