How to Adjust Rear Drum Brakes in Reverse

Maintaining your vehicle's brake system is crucial for ensuring safety on the road. One of the key components of many automobiles, especially older models, is the rear drum brake system. Over time, drum brakes can become out of adjustment, leading to decreased performance and safety risks. One effective technique for adjusting rear drum brakes is to perform the adjustment in reverse. This approach ensures that the brake shoes are properly seated against the drum, enhancing your vehicle's braking efficiency. Here’s a step-by-step guide on how to adjust rear drum brakes in reverse.

Tools and Materials Needed

Before you begin, gather the necessary tools and materials. You will need

- A jack and jack stands - A lug wrench - A brake adjusting tool or flathead screwdriver - Safety glasses - Brake cleaner (optional)

Step 1 Prepare Your Vehicle

First, park your vehicle on a flat, secure surface and engage the parking brake to prevent any unintended movement. Loosen the lug nuts on the rear wheels slightly while the wheels are still on the ground, but do not remove them completely.

Next, use the jack to lift your vehicle, then secure it with jack stands to ensure it's stable. Remove the wheels using the lug wrench to expose the rear drum brakes.

Once the drums are exposed, take a moment to inspect the brake components. Look for signs of wear on the brake shoes, drums, and other parts. If you notice excessive wear or damage, it’s advisable to replace them before proceeding with any adjustments.

If the components appear to be in good condition, you can clean the areas lightly with brake cleaner to remove any dust or debris. Remember to wear safety glasses to protect your eyes from brake dust.

Step 3 Adjusting the Brake Shoes

Locate the brake adjustment slot on the rear of the drum. This slot allows you to access the brake adjuster. Using the brake adjusting tool or a flathead screwdriver, you will need to turn the adjuster wheel. While doing this, ensure that you turn the adjuster in the appropriate direction—usually clockwise to tighten the shoes against the drum.

Step 4 Drive in Reverse to Seat the Shoes

Here comes the key part of the process. After adjusting the brake shoes, you need to drive the vehicle in reverse for a short distance. This step is crucial because it allows the brake shoes to automatically self-adjust and properly seat against the drum. While in reverse, apply the brakes gently and several times. This action helps align the shoes with the drum, ensuring that the brakes engage optimally.

Step 5 Recheck the Adjustment

After driving in reverse, return to your garage or the area where you completed the adjustment. Lift the vehicle back up, remove the wheels, and inspect the brake drum to ensure everything looks secure. Check the adjustment again by spinning the drum; it should rotate freely without any rubbing. If you hear or feel any interference, you may need to readjust the brakes.

Step 6 Reassemble and Test Drive

Once the brakes are adequately adjusted and you're satisfied that there’s no rubbing or unusual noise, reassemble the brake components by putting the wheels back on and tightening the lug nuts. Finally, lower the vehicle back to the ground.

Take your vehicle for a test drive to ensure that the brakes are functioning correctly. Pay attention to how the vehicle brakes while driving slowly and at higher speeds. If everything feels right, you’ve successfully adjusted your rear drum brakes.

Conclusion

Adjusting rear drum brakes in reverse is a time-tested method that can help maintain optimal braking performance while ensuring your safety on the road. Regular checks and adjustments can help extend the life of your brake system and improve your vehicle’s overall performance. If you’re unsure or uncomfortable performing this procedure, consider consulting a professional mechanic for assistance.
