Which Way to Turn Drum Brake Adjuster A Guide for DIY Enthusiasts

Proper maintenance of your vehicle’s braking system is crucial for safe driving. Among the various components of drum brakes, the adjuster plays a vital role in ensuring your brakes function effectively. However, many vehicle owners are often confused about how to adjust the drum brake, particularly when it comes to which way to turn the brake adjuster. This article aims to illuminate this topic and provide a step-by-step guide for those inclined towards DIY vehicle maintenance.

Understanding Drum Brakes and Their Components

Before delving into adjustments, it’s essential to understand how drum brakes work. When you press the brake pedal, hydraulic fluid pushes the brake shoes outward against the drum, creating friction that slows down the vehicle. Over time, brake shoes wear down, and the drum’s inner surface can also exhibit wear. To maintain optimal braking efficiency, it is crucial to keep the shoes adjusted close to the drum without causing friction when the brakes aren't engaged.

The adjuster is a critical component that regulates the distance between the brake shoes and the drum. It is usually located at the bottom of the brake assembly and can be manually adjusted. However, knowing which direction to turn the drum brake adjuster can be confusing.

Which Way to Turn the Drum Brake Adjuster

When it comes to turning the drum brake adjuster, it generally depends on the type of adjustment mechanism installed in your vehicle. Most drum brakes utilize either a star wheel adjuster or a screw-type adjuster. Here’s how to handle each

1. Star Wheel Adjuster This is the most common type of adjuster found in drum brakes. It is shaped like a star and can be turned with a brake adjusting tool. To tighten the brake shoes (move them closer to the drum), you typically need to turn the adjuster upwards or counterclockwise. On the other hand, to loosen the shoes (move them away from the drum), turn the adjuster downwards or clockwise.

2. Screw-Type Adjuster In some vehicles, a screw-type mechanism is used. For these adjusters, turning the screw clockwise usually tightens the brake shoes, while turning it counterclockwise loosens them. However, it is always advisable to check the vehicle’s service manual since the direction can vary by make and model.

Step-by-Step Guide to Adjusting Drum Brake

1. Safety First Always ensure your vehicle is on a flat surface, and use wheel chocks to prevent it from rolling. Engage the parking brake for added security.

2. Remove the Wheel Use a lug wrench to remove the wheel covering the drum brake system. This usually requires loosening the lug nuts and lifting the vehicle with a jack.

3. Access the Brake Assembly Once the wheel is off, you can see the brake drum. Remove it by unscrewing any retaining screws if applicable.

4. Locate the Adjuster Find the star wheel or screw-type adjuster at the bottom of the brake assembly.

5. Adjust the Brake Shoes Using your preferred tool - For a star wheel, turn it upwards for tightening or downwards for loosening. - For a screw-type, turn clockwise to tighten and counterclockwise to loosen.

6. Check the Clearance After adjusting, spin the drum by hand. If it spins freely with no dragging sound, you have successfully adjusted it. If it’s hard to turn, you may need to back off slightly.

7. Reassemble and Test Once satisfied with the adjustment, reattach the drum and wheel. Lower the vehicle and take it for a test drive to ensure the brakes perform correctly.

Conclusion

Adjusting the drum brake adjuster is an essential skill for any DIY vehicle owner. By understanding which way to turn the adjuster and following the steps outlined, you can ensure that your drum brakes remain in optimal condition. Always remember to consult your vehicle’s service manual for specific instructions tailored to your make and model, and when in doubt, seek professional help. Safe driving starts with a reliable braking system!
