How to Get Springs Back on Drum Brakes

Drum brakes are a critical component of many vehicles, providing the necessary stopping power by utilizing friction to slow down the wheels. One of the essential parts of drum brake systems is the springs. They play a vital role in maintaining proper function and ensuring that the brake components return to their resting positions after brake application. Over time, these springs may require replacement or reinstallation due to wear or misalignment. In this article, we will guide you through the process of getting springs back on drum brakes efficiently and safely.

Understanding Brake Springs

Before we delve into the installation process, it's essential to understand the types of springs typically found in drum brake systems. There are usually two types of springs primary and secondary return springs. The primary springs are responsible for retracting the brake shoes back to their original positions when the brakes are released, while the secondary springs provide additional tension and stability during braking.

Tools and Materials Needed

To reinstall or replace springs on drum brakes, you will need a few essential tools and materials

- Brake spring tool or pliers - Screwdriver (flathead and Phillips) - Wrench or socket set - Clean, lint-free cloth - Brake cleaner or solvent - Replacement springs (if necessary)

1. Safety First Before starting any brake work, ensure the vehicle is parked on a level surface. Set the parking brake and use wheel chocks to prevent the vehicle from rolling. Wear safety glasses and gloves to protect yourself during the process.

2. Remove the Wheel and Drum Use a lug wrench to remove the lug nuts and take off the wheel. Once the wheel is removed, you may need to take off the brake drum. Check if there are any retaining screws or clips holding the drum in place. If the drum is stuck, lightly tap it with a mallet to loosen it.

3. Inspect the Brake Assembly With the drum removed, take a moment to inspect the brake components. Look for any signs of wear on the brake shoes, springs, and other hardware. If the springs are damaged or significantly worn, replace them before reinstallation.

4. Understand the Spring Placement Familiarize yourself with how the springs are arranged in the brake assembly. It’s helpful to take a picture or refer to a service manual if you're unsure. This will guide you in placing the springs back correctly.

5. Reinstall the Springs Using the brake spring tool or pliers, carefully attach the springs back to their respective anchor points. Start with the primary springs, as they are crucial for the retraction of the brake shoes. Once the primary springs are secured, follow by installing the secondary springs, ensuring they are properly tensioned but not over-stretched.

6. Check the Brake Shoes Alignment Ensure that the brake shoes are aligned correctly before reattaching the drum. They should sit flush against the backing plate, and the springs should have enough tension to return the shoes once the brake pedal is released.

7. Reattach the Brake Drum and Wheel Once you are satisfied with the spring installation and shoe alignment, reattach the brake drum. Ensure that it spins freely. Then, replace the wheel and hand-tighten the lug nuts before lowering the vehicle and tightening them fully to the manufacturer's specifications.

8. Test the Brakes Before hitting the road, pump the brake pedal a few times to ensure the brake shoes are seated correctly. Perform a low-speed test drive to confirm everything is functioning correctly.

Conclusion

Reinstalling springs on drum brakes is a task that requires careful attention to detail and proper tools. By following this guide, you can ensure that your drum brake system functions safely and effectively. Regular maintenance of your braking system not only extends its life but also guarantees that your vehicle operates safely on the road. Always prioritize safety, and if in doubt, consult a professional mechanic for assistance.
