How to Adjust the E-Brake on Drum Brakes

The parking brake, commonly known as the e-brake, is an essential component of any vehicle's braking system, particularly for those equipped with drum brakes. Proper adjustment ensures safety and the optimal performance of your vehicle. Here’s a comprehensive guide on how to adjust the e-brake on drum brakes.

Tools Needed

Before you start, gather the following tools - Jack and jack stands - Lug wrench - Wrench set - Screwdriver - Brake cleaner (optional) - Gloves and safety glasses

Step 1 Prepare Your Vehicle

1. Park on a Level Surface Ensure your vehicle is parked on a flat surface to provide stability. 2. Engage the Current E-Brake Activate the parking brake to prevent the car from rolling while you work. 3. Loosen the Wheels Use the lug wrench to loosen the lug nuts of the rear wheels, but do not remove them completely yet.

1. Jack Up the Car Use the jack to lift the rear of the vehicle and secure it with jack stands. Ensure it is stable before proceeding. 2. Remove the Wheels Once the car is securely elevated, remove the lug nuts and take off the rear wheels to expose the drum brakes.

Step 3 Inspect the Brakes

While you have access to the drum brakes, it’s a good idea to inspect the condition of the brake shoes and drums. Look for wear and tear; if they are significantly worn, consider replacing them.

Step 4 Adjusting the E-Brake

1. Locate the Adjusting Mechanism On most drum brake systems, there’s an adjusting wheel or lever accessible through the backing plate of the drum. 2. Make the Adjustment Using a screwdriver or wrench, turn the adjusting mechanism. If tightening is necessary, rotate it in the direction indicated (usually clockwise) until you feel resistance. Doing so will expand the brake shoes, making contact with the drum. 3. Check the Function After making the adjustment, rotate the drum by hand. It should turn without significant resistance but should not spin freely. Repeat the adjustment if necessary.

Step 5 Reassemble

1. Reinstall the Drum and Wheel Once satisfied with the adjustment, reinstall the drum (if applicable) and then the wheel. Secure it with the lug nuts. 2. Lower the Vehicle Carefully lower the vehicle back to the ground and remove the jack stands. 3. Test the E-Brake Finally, engage and release the e-brake several times, ensuring that it holds the vehicle securely when in the on position.

Conclusion

Adjusting the e-brake on drum brakes is a straightforward process that can significantly enhance your vehicle's safety and functionality. Regular checks and adjustments will help maintain optimal braking performance and prolong the lifespan of your braking system. If you’re ever unsure, consult a professional mechanic for assistance.
