Steps to Reinstall Springs on Drum Brake Systems Effectively and Safely

How to Put Springs Back on Drum Brakes A Step-by-Step Guide

Drum brakes are a common type of braking system found in many vehicles, especially older models. They function by using a set of brake shoes that clamp against a spinning drum when you press the brake pedal. One essential component of drum brakes is the springs that hold the brake shoes in place. When replacing brake shoes or performing maintenance, you may need to reinstall these springs. This article will guide you through the process of putting springs back on drum brakes safely and effectively.

Tools and Materials Needed

Before starting the process, gather the necessary tools and materials

1. Brake Spring Tool This specialized tool will help you manipulate the springs easily. 2. Pliers Both needle-nose and regular pliers may be useful. 3. Safety Goggles Protect your eyes from flying debris. 4. Wrenches/Sockets To remove any necessary components. 5. Brake Cleaner To clean the drum and shoes. 6. New Brake Shoes and Springs If the old components are worn out.

Step 1 Prepare the Vehicle

Firstly, ensure the vehicle is parked on a flat surface and the parking brake is engaged. Use wheel chocks to prevent any movement. Then, loosen the lug nuts and jack up the vehicle. Remove the wheel to access the drum brake assembly.

Step 2 Remove the Drum

Once the wheel is removed, inspect the brake drum. If the drum is held in place with retaining screws, remove them using a screwdriver. Gently pull the drum off. If it’s stuck, you can tap it lightly with a hammer to loosen it. In cases of excessive rust or debris, use a brake cleaner to clean the drum’s surface.

Step 3 Remove Old Components

With the drum removed, you will see the brake shoes and the springs. Before removing anything, take a picture or make a note of how the old springs and shoes are arranged. This will serve as a reference for reinstallation. Use the brake spring tool, pliers, and wrenches to carefully remove the old brake shoes and springs.

Before installing new parts, clean the brake assembly with brake cleaner. This removes dust and debris that could interfere with performance. Inspect the drum for signs of wear or damage. If it's excessively worn, consider replacing it.

Step 5 Install New Brake Shoes

Attach the new brake shoes first. Align them with the hardware and sponge them into place. Make sure they fit snugly against the backing plate. Generally, the leading edge of the brake shoe should be positioned towards the front of the vehicle.

Step 6 Attach the Springs

Now, it’s time to install the springs. Start with the return springs, which pull the shoes back after braking. Use the brake spring tool to stretch and position the spring hooks correctly. Ensure they are secured in their designated holes.

Next, install the hold-down springs that keep the shoes in place. Align the shoes properly and use your pliers to push the spring down into the hold-down post. This is crucial, as incorrectly installed springs can lead to brake failure. Be sure to check that all parts are correctly aligned and secured.

Step 7 Reassemble the Drum

Once all springs and shoes are installed correctly, carefully slide the drum back over the shoes. Ensure that it rotates freely without binding. Now, reapply any retaining screws if needed, then proceed to put the wheel back on.

Step 8 Test the Brakes

Before operating the vehicle, press the brake pedal a few times to ensure the shoes are positioned correctly and the springs have settled. Check for any unusual noises or issues when driving at low speeds.

Conclusion

Reinstalling springs on drum brakes can be a daunting task for many, but with the right tools, patience, and attention to detail, it can be accomplished successfully. Always remember that your vehicle’s braking system is critical for safety, so if you have any doubts about the process, it’s best to consult a professional mechanic. Properly maintained drum brakes will ensure safer driving experiences and longevity for your vehicle.
