How to Adjust Brake Drum Shoes

Properly adjusting brake drum shoes is crucial for ensuring your vehicle's braking system functions effectively and safely. Over time, brake shoes can wear down or become misaligned due to regular usage, leading to decreased braking performance, uneven wear, and potential safety hazards. Here’s a step-by-step guide to help you understand how to adjust brake drum shoes.

Tools and Safety

Before starting the adjustment process, gather the necessary tools, including a jack, jack stands, a lug wrench, a brake adjustment tool (or flathead screwdriver), and safety goggles. Always prioritize safety make sure your vehicle is on a level surface, and wear safety glasses to protect your eyes from debris.

Step 1 Remove the Wheel

Begin by loosening the lug nuts on the wheel you plan to work on. Use the lug wrench to loosen, but do not completely remove the nuts yet. Then, using the jack, lift the vehicle off the ground and secure it with jack stands. Once the vehicle is stable, completely remove the lug nuts and take off the wheel to access the brake drum.

Step 2 Inspect the Brake Components

With the brake drum exposed, inspect the brake shoes for wear. Check for uneven wear patterns and make sure there’s adequate lining left on the shoes. If the shoes are excessively worn or damaged, consider replacing them before making any adjustments.

Step 3 Adjust the Brake Shoes

Many brake drum systems include an adjustment wheel or star wheel mechanism accessed through a hole in the backing plate. If your model has an access hole, use a flathead screwdriver to turn the adjustment wheel. Turning it clockwise will expand the shoes, bringing them closer to the drum, while turning it counterclockwise will retract them.

To adjust the shoes, perform the following

1. Expand the Shoes Gradually turn the adjustment tool clockwise until the shoes make contact with the drum. You'll often hear a light scraping sound, which indicates they are close to the drum’s surface.

2. Check the Movement After expanding, try spinning the drum. It should turn with some resistance but not be overly tight. If it doesn't rotate freely, back off the adjustment slightly until you achieve the right balance.

3. Repeat for the Opposite Side If you're adjusting one side, it’s a good idea to adjust the other side to ensure even performance throughout the braking system.

Step 4 Reassemble and Test

Once you’re satisfied with the adjustment, put the brake drum back on and replace the wheel. Securely tighten the lug nuts by hand before lowering the vehicle. Once the vehicle is back on the ground, use the lug wrench to fully tighten the nuts in a star pattern for even pressure.

Step 5 Test the Brakes

Before hitting the road, it’s essential to test the brakes. Start the vehicle and press the brake pedal a few times to ensure everything is functioning correctly. Take the vehicle for a short, slow drive in a safe area, applying the brakes gently to confirm they engage smoothly and effectively.

Conclusion

Regularly adjusting your brake drum shoes is a vital part of vehicle maintenance that can enhance safety and prolong the life of your braking system. By following these straightforward steps, you’ll ensure your brakes do their job effectively, providing you with peace of mind on the road. Always consult your vehicle's manual for specific instructions and recommendations, and when in doubt, seek professional assistance.
