Drum brakes, commonly found on older vehicles and some newer cars, are one of the two primary types of braking systems used in automobiles. While disc brakes have become more prevalent in recent years, drum brakes still persist in certain vehicles. But like any braking system, drum brakes require regular maintenance, including adjustments. In this article, we will provide you with a step-by-step guide on how to adjust drum brakes and answer some frequently asked questions.

Why should you adjust drum brakes?

Drum brakes need regular adjustments to maintain their optimal performance. Over time, the brake shoes might wear out, causing the drum brakes to lose effectiveness. Adjusting drum brakes ensures that the shoes are positioned correctly against the drum, allowing the brakes to perform efficiently.

When should you adjust drum brakes?

It is recommended to adjust drum brakes at least once a year, or every 12,000 miles. However, it’s crucial to pay attention to signs of diminished braking performance. If you notice your vehicle taking longer to stop or hear a scraping noise when braking, it’s an indication that the drum brakes might require adjustment.

What tools do you need?

– Jack and jack stands
– Lug wrench
– Brake spoon
– Flathead screwdriver
– Brake cleaner
– Brake lubricant

Step-by-Step Guide to Adjust Drum Brakes:

Step 1: Safety first!
Before beginning any work on your vehicle, ensure it is parked on a level surface. Engage the parking brake and chock the wheels to prevent accidental movement. Additionally, make sure you have the necessary tools mentioned earlier.

Step 2: Lift the vehicle
Using the jack, lift one end of the vehicle at a time, allowing you to access the wheels.

Step 3: Remove the wheel
Using a lug wrench, loosen the lug nuts on the wheel you are working on. Once loose, raise the vehicle higher using the jack stands, remove the lug nuts, and carefully take off the wheel.

Step 4: Inspect the drum brakes
Take a close look at the drum brakes to ensure there are no signs of extensive damage. Look for any significant wear on the brake shoes, as this may require replacement rather than adjustment.

Step 5: Adjust the brakes
Using a flathead screwdriver, locate the brake adjuster hole generally accessible on the rear side of the drum brake assembly. Insert the screwdriver and turn it until you feel a slight resistance. This action adjusts the brake shoes closer to the drum.

Step 6: Spin the drum
After adjusting the brakes, spin the drum by hand. It should have slight resistance but should still rotate freely. If it feels too tight, you need to back off the brake adjuster slightly.

Step 7: Clean and lubricate
At this stage, use a brake cleaner to remove any dust, debris, or oil from the drum brakes. Apply a thin layer of brake lubricant to the contact points of the shoes, ensuring smooth operation.

Step 8: Repeat the process
Follow steps 5 to 7 for the remaining drum brakes on the vehicle, repeating the adjustment process until all brakes are checked and adjusted.

Step 9: Reinstall the wheel
Carefully place the wheel back onto the vehicle’s hub and tighten the lug nuts by hand. Once secure, lower the vehicle using the jack and tighten the lug nuts fully using the lug wrench.

With regular care and maintenance, drum brakes can continue to perform optimally. By following this step-by-step guide, you can efficiently adjust your drum brakes and ensure their longevity. Remember to always pay attention to signs of diminished braking performance and attend to the issue promptly. Properly functioning drum brakes are vital for your safety and the safety of others on the road.
