How to Convert Rear Drum Brakes to Disc A Comprehensive Guide

Converting rear drum brakes to disc brakes can significantly enhance the braking performance of your vehicle. Many car enthusiasts opt for this upgrade to improve safety, handling, and overall driving experience. This article will guide you through the process of converting rear drum brakes to disc, detailing necessary tools, steps involved, and potential challenges.

Understanding the Benefits

Before diving into the conversion process, it's essential to understand the advantages of disc brakes over drum brakes. Disc brakes generally provide better stopping power, dissipate heat more effectively, and are less prone to brake fade. Additionally, they often require less maintenance and offer a more consistent performance in various driving conditions.

Tools and Materials Needed

Before starting your conversion, gather the following tools and materials

1. Tools - Jack and jack stands - Wrench set - Socket set - Brake bleeder kit - Torque wrench - Screwdrivers - Pliers - Hammer - Safety glasses and gloves

2. Materials - Disc brake conversion kit (specific to your car model) - Brake pads - New calipers - Brake rotors - Brake lines (if required) - Brake fluid - New rear wheel bearings (if necessary)

Step-by-Step Conversion Process

1. Preparation Begin by parking your vehicle on a flat surface and ensuring the parking brake is engaged. Gather all your tools and materials within easy reach. Ensure you are wearing safety gear.

2. Removing the Wheel Use a jack to lift the rear of your vehicle and secure it with jack stands. Remove the rear wheels to access the drum brakes.

3. Removing the Drum Brakes Take off the brake drum by removing the retaining screws or bolts. You might need to tap it gently with a hammer if it’s stuck. Once removed, disconnect the brake lines and other components associated with the drum brakes.

4. Preparing for Drum to Disc Conversion Depending on your specific conversion kit, you may need to install new backing plates or brackets. Follow the instructions provided with the kit carefully to ensure proper alignment and fit.

5. Installing the Disc Brakes Attach the new brake calipers to the mounting brackets according to your conversion kit. Ensure that the calipers are positioned correctly so that they can effectively clamp onto the brake rotors.

6. Mounting the Rotors Slide the new brake rotors onto the wheel hub. Ensure that they are properly seated and aligned. Some kits may require new wheel bearings, so check the compatibility based on your particular setup.

7. Connecting Brake Lines If your conversion kit requires new brake lines, install them according to the manufacturer’s instructions. Ensure all connections are secure and there are no leaks.

8. Bleeding the Brakes After the installation is complete, it’s crucial to bleed the brake system to remove any air pockets. Use a brake bleeder kit to facilitate this process. Begin bleeding the brakes farthest from the master cylinder and work your way inwards.

9. Reinstalling the Wheels Once the brake system is bled and you are confident everything is properly installed, reinstall the wheels. Tighten the wheel nuts to the manufacturer’s specified torque.

10. Testing Lower the vehicle back to the ground. Before driving, press the brake pedal several times to ensure the calipers engage and the brakes function correctly. Take the vehicle for a test drive in a safe environment to check the new brakes’ performance.

Challenges and Considerations

While converting rear drum brakes to disc can improve your vehicle's performance, be aware that this task requires mechanical knowledge and attention to detail. Ensure you follow all safety protocols to avoid accidents. Additionally, consider consulting a professional if you are unsure at any stage of the process.

Conclusion

Upgrading from rear drum brakes to disc brakes can dramatically improve your vehicle’s braking system, enhancing safety and performance. By following this comprehensive guide, you can successfully make this upgrade with the right tools and knowledge. Remember to conduct regular maintenance on your new brake system to ensure longevity and reliability. Happy driving!
