Drum Brake Replacement A Comprehensive Guide

Drum brakes are a common braking system found in many vehicles, especially in older models and on the rear wheels of some newer cars. Unlike disc brakes, which utilize a flat rotor, drum brakes employ a cylindrical drum that rotates with the wheel. Inside the drum, brake shoes press against the drum's inner surface to create friction, thus slowing down the vehicle. While durable, drum brakes require periodic maintenance and replacement due to wear and tear. This article will guide you through the essential steps of drum brake replacement and highlight some crucial tips for the process.

Safety First

Before starting any automotive work, prioritize safety. Make sure your vehicle is on level ground and engage the parking brake. Use wheel chocks on the front wheels to prevent any movement while you're working.

Step-by-Step Replacement Process

1. Remove the Wheel - Loosen the lug nuts slightly before lifting the vehicle with a jack. Once elevated, remove the lug nuts completely and take off the wheel to expose the drum brake assembly.

2. Remove the Brake Drum - If the drum doesn’t slide off easily, you may need to remove retaining screws or gently tap it with a hammer. Inspect the drum for wear, cracks, or scoring, which may require replacement.

3. Disassemble the Brake Components - Take note of how the brake components are assembled, as you will need to replicate this during reassembly. Remove the brake shoes, springs, and any other attached hardware. It might be helpful to take pictures for reference.

4. Clean and Inspect - Thoroughly clean the brake assembly with brake cleaner to remove dust and debris. Examine the components for wear. Replace any parts that show significant signs of damage or corrosion.

5. Install New Brake Shoes - Follow the instructions provided in the replacement kit to install the new brake shoes. Ensure that all springs and hardware are correctly positioned according to your earlier notes or pictures.

6. Reassemble the Drum - Carefully reattach the drum over the new brake shoes. If you encounter resistance, check the positioning of the brake shoes and adjust as necessary.

7. Reattach the Wheel - Place the wheel back onto the hub, hand-tighten the lug nuts, and then lower the vehicle. Use a torque wrench to ensure that the lug nuts are tightened to the manufacturer’s specifications.

8. Test the Brakes - Once everything is reassembled, pump the brakes a few times before driving. This helps in setting the brake shoes properly against the drum. Conduct a slow test drive to ensure proper functionality.

Conclusion

Replacing drum brakes can be a rewarding DIY project that saves you money and enhances your vehicle's performance. Always consult your vehicle's service manual for specific instructions and safety guidelines. If at any point you feel unsure, don’t hesitate to seek assistance from a professional mechanic. Regular maintenance and timely replacement of brake components are vital to ensure your driving safety.
