How to Convert Drum Brakes to Disc Brakes

Converting drum brakes to disc brakes can significantly improve your vehicle's braking performance, enhance safety, and provide a more modern driving experience. Whether you’re upgrading for performance reasons, aesthetics, or simply because you want to utilize the benefits of disc brakes, this guide outlines the steps you'll need to take to make the conversion successfully.

Understanding Drum vs. Disc Brakes

Before diving into the conversion process, it’s essential to understand the differences between drum and disc brakes. Drum brakes utilize a system where brake shoes press against the inside of a drum to create friction and slow down the vehicle. On the other hand, disc brakes employ a rotor and caliper system that allows for more efficient heat dissipation, resulting in less brake fade and improved stopping power. This efficiency makes disc brakes a popular choice for performance vehicles and modern automobiles.

Why Convert?

1. Performance Improvement Disc brakes offer superior stopping power and better performance during wet conditions due to their design. 2. Maintenance Disc brakes tend to require less maintenance and are less prone to issues such as brake fade. 3. Upgraded Appearance Modern disc brakes often look more appealing, adding a sporty touch to your vehicle. 4. Availability of Replacement Parts Disc brake parts are widely available and can be easier to replace than drum brake components.

Tools and Materials Needed

Before starting the conversion, gather the necessary tools and materials, which may include

- New disc brake conversion kit (specific to your vehicle) - Brake rotors - Calipers - Brake pads - Brake lines - Jack and jack stands - Socket set - Wrenches - Torque wrench - Brake fluid - Safety glasses - Gloves

1. Preparation - Ensure the vehicle is on a flat surface. Use the jack to lift the vehicle and secure it with jack stands. - Remove the wheels and inspect the existing drum brake system.

2. Disassemble Drum Brakes - Remove the brake drums, which may involve taking off the axle cover if applicable. - Detach the brake shoes and springs carefully. Keep components organized for reference.

3. Install the New Disc Brake Components - Attach the new brackets that will hold the disc brake calipers. - Install the brake rotor onto the spindle where the drum used to be. - Fit the calipers onto the brackets, ensuring they align with the rotors. Secure them with the provided bolts.

4. Install Brake Lines - Replace the existing brake lines, if provided in your conversion kit, with those compatible with the disc brake setup. - Ensure all connections are tight and secure to prevent leaks.

5. Install Brake Pads - Place the new brake pads into the calipers. Follow the manufacturer's instructions for proper installation.

6. Reattach Wheels and Lower the Vehicle - Once everything is in place, reattach the wheels using proper torque specifications. - Lower the vehicle from the jack stands.

7. Bleed the Brakes - With the new brakes installed, it's crucial to bleed the brake system to remove any air bubbles in the brake lines. - This typically involves having someone pump the brake pedal while you open and close the bleed screws on each caliper.

8. Test Drive - Before hitting the road, ensure all tools are removed from the work area. Conduct a slow, cautious test drive to ensure the brakes are functioning correctly. Pay attention to any anomalies such as noises or a spongy brake pedal.

Conclusion

Converting from drum brakes to disc brakes can be a rewarding enhancement for your vehicle. With improved braking performance and a more modern look, this conversion can make a significant difference in your driving experience. Remember that it's essential to follow all safety guidelines during this process. If at any point you feel overwhelmed or unsure, do not hesitate to seek professional assistance. Happy driving!
