How to Change Drum Brakes into Disc Brakes

Converting drum brakes to disc brakes can enhance your vehicle's braking performance, providing better heat dissipation, improved stopping power, and a more responsive pedal feel. While the process can be complex and requires certain tools and skills, this guide will walk you through the steps to make the transition successfully.

Understanding Drum vs. Disc Brakes

Before diving into the conversion process, it's essential to understand the fundamental differences between drum and disc brakes. Drum brakes use friction created by brake shoes pressed against the inside of a rotating drum. This design can lead to brake fade, especially under heavy use, as heat builds up. In contrast, disc brakes utilize a caliper to squeeze brake pads against a rotating disc, allowing for more efficient cooling, reduced fading, and improved reliability.

Tools and Materials Needed

To convert your vehicle's drum brakes to disc brakes, you'll need several tools and materials, including

- Disc brake conversion kit (specific to your vehicle) - Brake fluid - Jack and jack stands - Lug wrench - Socket set - Torque wrench - Brake cleaner - Clamps (optional) - Safety glasses and gloves

1. Preparation and Safety Begin by parking your vehicle on a flat surface and ensuring it’s secured with wheel chocks. Wear safety glasses and gloves to protect yourself while working.

2. Raise the Vehicle Use a jack to lift the vehicle and support it securely with jack stands. Remove the wheels using the lug wrench.

3. Remove the Existing Drum Brakes - Detach the drum by removing the retaining screws (if applicable) and then pull the drum off the wheel hub. You may need to tap it lightly with a hammer if it’s stuck. - Once the drum is removed, disconnect the brake shoes, springs, and any other related hardware.

4. Install the New Disc Brake Assembly - Follow the instructions provided with your disc brake conversion kit closely, as configurations vary by kit and vehicle type. - Begin by installing the new brake rotor onto the wheel hub. Ensure it fits snugly and is properly aligned. - Next, mount the brake caliper bracket (if applicable) and ensure it is bolted securely according to the specified torque settings.

5. Attach the Caliper and Brake Pads - Place the brake pads into the caliper, then position the caliper over the rotor. Secure it using the provided bolts or pins. - Make sure everything is lined up correctly to avoid uneven wear.

6. Upgrade the Brake Lines Drum to disc brakes often require new brake lines. Follow the instructions in your kit to install the new lines, ensuring they don't pinch or rub against any moving parts. - Bleed the brake system to remove any air trapped in the lines, which could affect braking performance.

7. Reinstall the Wheels Once everything is in place and tightened to the proper specifications, reinstall the wheels. Make sure to tighten the lug nuts in a star pattern to evenly distribute pressure.

8. Test and Adjust With the vehicle back on the ground, pump the brake pedal a few times to ensure proper pad contact with the rotor. Check for any leaks at the brake lines and ensure that everything is functioning correctly.

Conclusion

Converting from drum brakes to disc brakes is a project that can significantly improve your vehicle's braking performance. While this guide covers the basic steps, always follow the specific instructions provided by the brake kit manufacturer. If you're not comfortable with any stage of this process, consult a professional mechanic. With patience and attention to detail, you'll enjoy the benefits of enhanced stopping power and increased safety on the road. Remember, a well-maintained braking system is crucial for any vehicle's performance and longevity.
