How to Adjust Brake Drums on Cars

Proper maintenance of your vehicle's braking system is crucial for safety and performance. Adjusting brake drums is an essential task that ensures your brakes function correctly, providing optimal stopping power. Here’s a step-by-step guide on how to adjust brake drums on cars.

Tools You Will Need

Before you start, gather the necessary tools

- Jack and jack stands - Lug wrench - Screwdriver - Brake drum adjustment tool (if available) - Brake cleaner - Clean rags or shop towels

Safety Precautions

Always prioritize safety when working on your vehicle. Ensure the car is on a level surface and engage the parking brake before lifting the vehicle. Wear safety glasses and gloves to protect yourself during the process.

Step 1 Lift the Vehicle

Begin by loosening the lug nuts on the wheel where you plan to adjust the brake drums. Use a lug wrench for this task. Once the lug nuts are loosened, use a jack to lift the vehicle and securely place it on jack stands. Ensure that the vehicle is stable before continuing.

Step 2 Remove the Wheel

Once the car is lifted, completely remove the lug nuts and take off the wheel. Set it aside in a safe location. You should now have clear access to the brake drum.

Step 3 Inspect the Brake Drums

Before making adjustments, inspect the brake drums for any signs of wear or damage. Look for grooves, cracks, or excessive rust. If the drums are damaged, they should be replaced rather than adjusted. Clean the surface of the drums with brake cleaner and a rag to remove any accumulated dust or debris.

Step 4 Adjusting the Brake Shoes

Locate the brake shoe adjustment access hole, which is usually found on the rear edge of the drum. If your drum has a slot, you can use a screwdriver to turn the adjuster mechanism. Turning it clockwise usually tightens the shoes while turning it counterclockwise loosens them.

Step 5 Check the Adjustment

As you adjust the brake shoes, spin the drum periodically. You want the drum to turn freely with slight resistance from the shoes. Once you feel that the adjustment is correct, ensure the drum can be turned by hand without excessive friction.

Step 6 Reinstall the Wheel

After making the adjustments, carefully reinstall the drum if removed, followed by the wheel. Hand-tighten the lug nuts initially, ensuring they are in place.

Step 7 Lower the Vehicle

Once the wheel is back on, lower the vehicle back to the ground using the jack and remove the jack stands. Tighten the lug nuts completely in a crisscross pattern to ensure even pressure.

Conclusion

Adjusting brake drums is a straightforward procedure that can enhance the performance and safety of your vehicle. Regular checks and adjustments to the braking system can prolong the life of your brakes and ensure optimal safety. If you’re ever unsure, consult a professional mechanic for assistance. Remember, a well-maintained braking system is vital for every driver.
