How to Use a Drum Brake Spring Tool

When it comes to maintaining your vehicle, understanding the components of the braking system is crucial, especially if you own a car with drum brakes. One of the essential tools for servicing drum brakes is the drum brake spring tool. This specialized tool simplifies the process of removing and installing springs in drum brake systems, which can often be challenging and time-consuming. In this article, we'll explore how to effectively use a drum brake spring tool to ensure safe and efficient brake maintenance.

Understanding Drum Brake Components

Before diving into the use of the drum brake spring tool, it’s essential to have a basic understanding of the components involved in a drum brake system. Drum brakes consist of several key parts, including

1. Brake Shoes These are the components that press against the drum to create friction and stop the vehicle. 2. Brake Drum The hollow cylinder that rotates with the wheel and is gripped by the brake shoes. 3. Springs The return springs and hold-down springs keep the brake shoes properly positioned and allow them to retract when the brakes are not engaged. 4. Adjuster This helps maintain the distance between the brake shoes and the drum for optimal braking performance.

Why You Need a Drum Brake Spring Tool

The brake springs in drum brake systems can be quite strong, making them notoriously difficult to handle without the right tools. Attempting to remove or install these springs by hand can lead to injuries or damage to other components. A drum brake spring tool provides the leverage and grip required to manage these springs safely and effectively.

Steps for Using a Drum Brake Spring Tool

1. Gather Your Tools In addition to the drum brake spring tool, ensure you have a socket set, a wrench, a brake cleaner, and a new set of brake shoes and springs if you plan to replace them.

2. Prepare the Vehicle Start by safely lifting the vehicle using a jack and securing it on jack stands. Remove the wheel to access the drum brake.

3. Remove the Brake Drum If necessary, remove the retaining screws or hold-down springs and slide the brake drum off. This will expose the brake shoes and springs.

4. Using the Spring Tool - Removing Springs Attach the hooks of the drum brake spring tool to the spring you want to remove. Pull the handles of the tool apart to stretch the spring, and then carefully release it from its anchor point. Be cautious as the spring may snap back. - Installing Springs Position the brake shoe in place, making sure the hold-down and return springs are correctly situated. Use the drum brake spring tool to stretch the spring over its anchor. Slowly release the handles to let the spring settle into place securely.

5. Reassemble the Brake Assembly Once all springs are installed, position the brake drum back over the shoes and secure it according to the manufacturer’s specifications.

6. Test Your Brakes Before driving, make sure to pump the brake pedal a few times to ensure the brakes are engaging correctly. It’s always a good idea to drive at low speed initially to test your repairs.

Safety Tips

- Always wear safety glasses and gloves when working on your brakes. - Double-check that all components are securely in place before lowering the vehicle. - If you feel unsure at any point in the process, consult a professional mechanic.

Conclusion

Using a drum brake spring tool can make the process of working on drum brakes significantly easier and safer. By understanding the components and following the correct procedures, you can maintain your vehicle’s braking system effectively. Whether you're a seasoned mechanic or a DIY enthusiast, having the right tools and knowledge will help you tackle brake jobs with confidence. Remember, proper maintenance of your brakes is vital for your safety on the road.
