How to Adjust Drum Brakes by Backing Up

Drum brakes are a common feature on many vehicles, particularly older models. Unlike disc brakes, which are easier to identify and maintain, drum brakes can be a bit more complex. However, adjusting them by backing up is a straightforward process that can enhance safety and improve the overall performance of your braking system.

Understanding Drum Brakes

Before diving into the adjustment process, it's essential to understand how drum brakes work. Inside the drum are brake shoes that expand against the inside of the drum when the brakes are applied. Over time, these shoes can wear down, leading to a gap between the shoes and the drum. This gap can reduce braking efficiency, making adjustments necessary.

Tools Needed

To adjust your drum brakes, you will need a few basic tools - A jack and jack stands to lift the vehicle safely - A lug wrench - A brake adjuster tool or a flathead screwdriver

Steps to Adjust Drum Brakes by Backing Up

1. Safety First Begin by ensuring your vehicle is parked on a level surface. Engage the parking brake to prevent any unexpected movement.

2. Lift the Vehicle Use the jack to raise the vehicle and secure it with jack stands. Remove the wheel to gain access to the drum.

3. Inspect the Brake Components Before adjusting, visually inspect the brake shoes and drum for wear and tear. If the shoes are worn down significantly, they may need replacing instead of just adjusting.

4. Locate the Adjusting Mechanism Most drum brakes have an adjustment spoon or wheel located at the bottom of the assembly. This mechanism allows you to expand or contract the brake shoes.

5. Adjust the Brakes Insert your tool into the adjuster and turn it in the appropriate direction to tighten the shoes against the drum. Be careful not to over-adjust, as this may cause the brakes to drag.

6. Back Up to Set the Adjustment Once adjusted, it’s time to set the brakes properly. Slowly back the vehicle up while gently applying the brakes. This action allows the shoes to seat against the drum, ensuring a proper fit.

7. Recheck the Adjustment After backing up, check your work by pressing the brake pedal a few times and inspecting the gap between the shoes and drum. If necessary, repeat the adjustment process until you achieve a snug fit.

8. Reassemble and Test Replace the wheel, lower the vehicle, and test the brakes at low speed to ensure they function correctly.

Conclusion

Adjusting drum brakes by backing up is a simple yet effective maintenance task that can improve your vehicle's braking performance. Regular adjustments not only enhance safety but also prolong the life of your brake components. Always be attentive during the process, and don't hesitate to seek professional help if you're unsure about any steps. Safe driving!
