How to Use a Drum Brake Spring Tool

Drum brakes are a common braking system found in many vehicles, particularly older models and light-duty trucks. While they are effective, they can be challenging to service, especially when it comes to replacing or adjusting the brake springs. This is where a drum brake spring tool comes into play. This article will guide you through the process of using a drum brake spring tool effectively and safely.

What is a Drum Brake Spring Tool?

A drum brake spring tool, also known as a drum brake spring compressor or brake spring tool, is a specialized tool designed to install and remove the springs that hold the brake shoes in place inside the drum. These springs are under considerable tension, and handling them requires care to prevent injury or damage to components.

Why Use a Drum Brake Spring Tool?

Using a dedicated tool helps simplify the task and ensure that the springs are installed correctly. The risk of springs snapping back or incorrectly positioning the brake shoes is significantly reduced when a proper tool is used. This not only makes the job easier but also enhances the overall safety of the braking system.

Tools and Safety Gear Needed

Before you get started, gather the following tools and safety gear

1. Drum Brake Spring Tool Ensure that you have a tool that fits your specific brake model. 2. Socket Set and Ratchet For removing the drum and adjusting brake components. 3. Brake Cleaner To clean any grime or brake dust off the components. 4. Safety Glasses To protect your eyes from flying debris. 5. Gloves To keep your hands safe and clean.

1. Prepare the Work Area - Ensure your vehicle is on a flat surface. - Engage the parking brake. - Use wheel chocks on the front wheels if you’re working on the rear brakes.

2. Remove the Wheel and Brake Drum - Use the socket set to remove the lug nuts and take off the wheel. - Then, remove the brake drum by pulling it straight off after ensuring that it is not corroded or stuck.

3. Inspect the Brake Components - Before proceeding with spring installation or removal, inspect the brake shoes, wheel cylinder, and other components for wear or damage.

4. Using the Drum Brake Spring Tool - When using the drum brake spring tool, position it around the spring you wish to install or remove. - If you’re removing the spring, pull the handle of the tool to compress the spring. This will relieve tension on the spring, allowing you to safely detach it from the brake shoe. - For installation, place the spring in the correct position on the brake shoe, then use the tool to stretch the spring back into place without risking injury.

5. Check Alignment - Once the springs are in place, ensure that each component is aligned correctly. The brake shoes should be parallel, and any adjusting screws or clips should be firmly secured.

6. Reassemble - After you have replaced the springs and ensured everything is set, place the brake drum back onto the wheel hub. - Reattach the wheel and tighten the lug nuts in a star pattern to ensure even pressure distribution.

7. Test the Brake System - Before driving, pump the brake pedal a few times to seat the shoes against the drum. - Take the vehicle for a slow test drive to ensure everything operates smoothly.

Conclusion

Using a drum brake spring tool can significantly ease the process of servicing drum brakes. By following safety guidelines and taking the time to work carefully, you can effectively replace and adjust your brake springs. Always remember to check your work once completed and drive cautiously during the initial test run to ensure that every component operates effectively. With practice, you’ll become proficient in using this essential tool, making brake maintenance a more manageable task.
