Steps for Properly Adjusting Your Brake Drums for Optimal Performance

How to Adjust Brake Drums A Comprehensive Guide

Brake drums are an integral component of a vehicle's braking system, particularly for older cars and certain heavy-duty vehicles. Proper adjustment of brake drums ensures safe and efficient braking, prolongs the lifespan of brake components, and enhances overall vehicle performance. This guide will outline the steps to adjust brake drums correctly and safely.

Understanding Brake Drum Brakes

Brake drums use friction to slow down or stop the vehicle. When the brake pedal is pressed, hydraulic pressure pushes the brake shoes against the inner surface of the drum. As the brake shoes wear down over time, they must be adjusted to maintain optimal contact with the drum for effective braking.

Tools and Materials Needed

Before you start, ensure you have the following tools and materials

- Jack and jack stands - Lug wrench - Brake drum adjustment tool or screwdriver - Brake cleaner - Rags - Safety goggles - Gloves

Step-by-Step Guide to Adjusting Brake Drums

1. Safety First Park your vehicle on a flat, stable surface, engage the parking brake, and wear safety goggles and gloves.

2. Remove the Wheel Loosen the lug nuts using the lug wrench, then raise the vehicle with a jack and secure it on jack stands. Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components With the wheel off, inspect the brake drum and shoes for wear or damage. If the shoes are excessively worn, it may be time to replace them.

4. Remove the Brake Drum If necessary, remove the brake drum. It may require some force if it's stuck due to corrosion or wear. Use a brake drum puller if needed.

5. Locate the Adjustment Mechanism Inside the brake assembly, locate the adjustment mechanism. This is usually a starwheel or a threaded adjuster that can be turned to expand or retract the brake shoes.

6. Adjusting the Brake Shoes - To expand the shoes (if they’re too far from the drum), turn the adjustment mechanism in the appropriate direction. For most vehicles, this means turning the starwheel upward. - To retract the shoes, turn the mechanism in the opposite direction. Adjust until the shoes are close to the drum, creating slight resistance when you rotate the drum by hand.

7. Reinstall the Drum Once adjusted, reinstall the brake drum. Ensure it spins freely without any binding. If it binds, readjust the shoes.

8. Reassemble the Wheel Place the wheel back onto the hub. Hand-tighten the lug nuts, lower the vehicle off the jack stands, and then tighten the nuts to the manufacturer’s specifications with the lug wrench.

9. Test the Brakes Before driving, pump the brake pedal a few times to seat the shoes against the drum. Then, perform a static test by driving at low speed and applying the brakes to ensure they engage smoothly and effectively.

10. Regular Maintenance Regularly check and adjust your brake drums as part of your vehicle maintenance schedule. This can help prevent uneven wear and premature failure.

Conclusion

Adjusting brake drums is a crucial maintenance task that can significantly affect your vehicle's safety and performance. By following these steps carefully and using the right tools, you can ensure that your braking system functions optimally. If you’re unsure or uncomfortable performing this task, it’s recommended to consult with a professional mechanic. Remember, safety on the road begins with properly functioning brakes.
