How to Use a Drum Brake Spring Tool A Comprehensive Guide

Maintaining your vehicle’s braking system is crucial for safety and performance. Among the many components that require attention, drum brakes are often overlooked. A key aspect of servicing drum brakes is handling the springs, which can be challenging without the right tools. The drum brake spring tool is specifically designed to make the installation and removal of brake springs safer and easier. This article will guide you through the process of using this essential tool effectively.

Understanding the Drum Brake System

Before diving into how to use the drum brake spring tool, it’s essential to grasp the basics of drum brake systems. Drum brakes consist of several components, including brake shoes, a drum, wheel cylinders, and springs. The springs help to hold the brake shoes in position and ensure they retract after braking. Over time, these springs can wear out or become corroded, necessitating replacement. This is where the drum brake spring tool comes into play.

Preparing for the Job

Before you start working on your drum brakes, ensure you have the following tools and materials

- A drum brake spring tool - Replacement springs - A brake cleaner - Safety goggles - Gloves - A socket set or wrench - A flathead screwdriver

Make sure you park your vehicle on a flat surface, engage the parking brake, and place wheel chocks behind the back wheels for stability.

1. Remove the Wheel and Drum Begin by loosening the lug nuts on the wheel, then lift the vehicle with a jack and remove the wheel. Next, remove the brake drum by pulling it straight off the wheel hub, taking care to check for any retained dust and debris.

2. Inspect the Brake Components Once the drum is off, inspect the brake shoes, wheel cylinder, and springs for any signs of wear or damage. This is a good time to clean any build-up with brake cleaner.

3. Using the Spring Tool

- Installation To install a new spring, position the spring hook of the drum brake spring tool around one end of the spring. Using the tool, pull the spring into position. Make sure the other end is correctly aligned with the respective hole or hook in the brake assembly. Slowly release the tension, allowing the spring to snap into place. Repeat this for each spring, ensuring they are securely attached. - Removal To remove the springs, insert the tool around the spring’s coil. Using leverage, pull the spring away from its attachment point. It’s crucial to control the release to prevent the spring from snapping back, which can cause injury or damage. If the springs feel stubborn, apply some penetrating oil and allow it to sit for a few minutes before attempting removal again.

4. Reassembly After replacing the springs, check to ensure the brake shoes are properly positioned. If needed, adjust the brake shoe spacing according to the manufacturer’s specifications.

5. Reattach the Drum and Wheel Once everything is secured, place the brake drum back over the shoes and reattach the wheel. Tighten the lug nuts in a star pattern to ensure even pressure.

6. Final Inspection Before lowering your vehicle, double-check that all components are firmly secured. Make sure no tools or parts are left inside the wheel area.

Conclusion

Using a drum brake spring tool may seem daunting at first, but with practice, it becomes an invaluable part of vehicle maintenance. Properly replacing and installing the springs ensures your brake system functions correctly, contributing to overall vehicle safety. If you ever feel unsure during the process, consult a professional mechanic or refer to your vehicle’s service manual for guidance. Regular maintenance of your braking system is not just about performance; it's about ensuring safety on the road. Happy braking!
