Instructions for Reinstalling Springs on Drum Brake Systems

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

Drum brakes play a crucial role in the braking system of many vehicles, and they rely on several components working in harmony to function effectively. One such component is the brake spring, which is vital for holding the shoes in the correct position and ensuring they retract when not in use. If you find yourself needing to replace or reattach springs on drum brakes, this guide will walk you through the process in a safe and efficient manner.

Tools and Materials You Will Need

Before you begin, gather the following tools and materials - Safety glasses and gloves - A brake spring tool (optional but recommended) - Pliers - A repair manual for your specific vehicle (for torque specifications and diagrams) - Replacement springs (if necessary)

Steps to Reattach Springs on Drum Brakes

1. Safety First Start by ensuring the vehicle is parked on a flat surface, and the engine is off. Always use wheel chocks on the opposite tires to prevent any rolling, and wear your safety equipment.

2. Remove the Wheel and Drum Using a lug wrench, remove the lug nuts and take off the wheel. Once the wheel is removed, access the brake drum by unscrewing any retaining screws or clips. Carefully slide the drum off, taking note of the orientation and any components visible.

3. Inspect the Brake Assembly Before reattaching the springs, inspect the entire brake assembly to ensure everything else is functioning correctly. Look for worn brake shoes, oil or grease leaks, and damaged components.

4. Identify the Springs Understand how the springs fit into the brake assembly. Typically, there are two types of springs return springs, which pull the brake shoes back to their resting position, and hold-down springs, which keep the shoes anchored.

5. Reattach the Hold-Down Springs Start with the hold-down springs. These are typically secured by a hold-down pin or cup. Use pliers to compress the spring and insert the hold-down pin through the spring and brake shoe. Make sure the spring is seated correctly and that everything is aligned with the manufacturer's specifications.

6. Install the Return Springs Next, focus on the return springs. These springs connect the shoes to the backing plate. Depending on your vehicle, you may need to use a brake spring tool to help stretch the spring into place. Be cautious when using any tools, as springs can snap back quickly if released improperly.

7. Recheck Everything Once all springs are in place, take a moment to double-check that all components are secured. A properly installed spring should not interfere with the movement of the brake shoes.

8. Reassemble the Drum and Wheel Slide the brake drum back into position and reinstall any screws or clips that hold it in place. After this, place the wheel back on and hand-tighten the lug nuts.

9. Torque the Lug Nuts With the wheel back in place, torque the lug nuts to the manufacturer’s specification to ensure they are secure.

10. Test the Brakes Finally, before taking the vehicle on the road, pump the brake pedal a few times to ensure everything is working correctly. This action helps seat the brake shoes against the drum.

Conclusion

Reattaching springs on drum brakes can seem daunting, but by following these steps, you can successfully complete the task and ensure your vehicle's braking system operates safely. If you feel uncomfortable at any stage, do not hesitate to consult a professional mechanic. Proper spring installation is critical for optimal braking performance, so attention to detail is important. Remember, safety first!
