How to Adjust Rear Drum Brakes in Reverse

Proper maintenance of your vehicle's braking system is crucial for ensuring safety and performance. One vital aspect of braking maintenance is the adjustment of rear drum brakes. If your vehicle is equipped with rear drum brakes, adjusting them appropriately can enhance braking efficiency and prolong the life of your brakes. This article will guide you through the process of adjusting rear drum brakes in reverse, an essential technique employed by many automotive experts.

Understanding Rear Drum Brakes

Rear drum brakes operate through a system of force exerted by the brake pedal. When you press the pedal, the brake shoes expand against the inside of a drum, creating friction that slows down the wheel. Over time, the brake shoes wear down, and the drum can become out of alignment, leading to decreased performance. Adjusting rear drum brakes in reverse is an often recommended method that helps ensure the shoes are correctly positioned for optimal braking performance.

Tools You'll Need

Before you begin the adjustment process, gather the necessary tools. Here's what you'll need - A jack and jack stands - A lug wrench - A brake adjusting spoon (or flat screwdriver) - A tape measure (optional) - Safety glasses and gloves

Step-by-Step Guide

1. Preparation Park your vehicle on a flat surface and turn off the ignition. Activate the parking brake for added safety.

2. Lifting the Vehicle Use the lug wrench to loosen the lug nuts of the rear wheels while the vehicle is still on the ground. Once loosened, lift the rear of the vehicle with a jack and secure it on jack stands.

3. Remove the Wheels Take off the lug nuts completely and remove the rear wheels to expose the drum brakes.

4. Inspect the Brakes Before making adjustments, visually inspect your brake shoes and drums for wear and damage. If the shoes are less than 1/16 inch thick, consider replacing them.

5. Locate the Adjuster On drum brakes, the adjusting mechanism is typically located at the bottom, between the brake shoes. Occasionally, the adjuster reaches out toward the rear of the vehicle—it’s crucial for this process.

6. Adjust the Brakes in Reverse To adjust the brakes while in reverse, you will need to rotate the adjusting screw. Use your brake adjusting spoon to turn the adjuster in the direction that expands the shoes—it’s generally clockwise. This process can be done manually, but would be more effective while the vehicle is in reverse.

7. Test the Adjustment With the drum still off, press the brake pedal slightly. This action will seat the shoes against the drum. Try to rotate the drum by hand. You’ll want to find the sweet spot where the drum barely rotates but can still turn easily. If it rotates too freely, tighten the shoes slightly.

8. Reassemble Once the adjustment feels correct, replace the drum, wheels, and lug nuts. Ensure everything is tightened securely.

9. Lower the Vehicle Carefully remove the jack stands and lower the vehicle back to the ground.

10. Repeat for the Other Side If you have not done so already, it is essential to repeat the process on the opposite side to ensure balanced braking performance.

Testing the Brakes

After all adjustments are made, take your vehicle for a slow test drive in a safe area. Pay attention to how the brakes feel; they should respond promptly and evenly. If any grinding sounds occur or if the brakes feel spongy, you may need to readjust them or consult a professional mechanic.

Conclusion

Adjusting rear drum brakes in reverse can significantly enhance braking performance and ensure your safety on the road. Regular brake maintenance, including adjustments, is key to prolonging the life of your brake system. With this step-by-step guide, you'll be better equipped to tackle the maintenance of your rear drum brakes and drive with confidence. Remember, if in doubt, it’s always best to seek professional assistance. Safe driving!
