How to Change Drum Brakes to Rotors

Upgrading your vehicle's braking system from drum brakes to disc rotors can significantly improve your car's performance, particularly in terms of stopping power and heat dissipation. While this task can be challenging, with the right tools and knowledge, it's possible to accomplish a successful conversion. This guide will walk you through the essential steps involved in changing drum brakes to rotors.

Understanding the Benefits of Disc Brakes

Before diving into the conversion process, it's crucial to understand why disc brakes are generally preferred over drum brakes. Disc brakes provide better performance in terms of heat management, which is particularly important during heavy braking situations. They also offer improved stopping power and a more consistent braking feel. Additionally, they are typically easier to maintain, as the components are more accessible for inspection and replacement.

Gathering the Necessary Tools and Parts

Before starting the conversion, ensure you have the following tools and parts - Disc brake conversion kit (including rotors, calipers, and brackets) - Brake pads - New brake lines (if needed) - Brake fluid - Basic hand tools (wrenches, sockets, screwdrivers) - Jack and jack stands - A torque wrench - Safety glasses and gloves

Step-by-Step Conversion Process

1. Prepare Your Vehicle Begin by parking your vehicle on a flat surface and engaging the parking brake. Loosen the lug nuts on the wheels you will be working on before lifting the vehicle with a jack. Secure it with jack stands for safety.

2. Remove the Wheel and Brake Assembly Once the vehicle is secure, remove the wheel. Next, detach the drum brake assembly. This usually involves removing the retaining clips, pulling off the drum, and removing the brake shoes, springs, and any associated hardware.

3. Inspect and Clean the Hub With the drum removed, inspect the hub for any damage or wear. Clean the surface of the hub to ensure a proper mounting surface for the new rotors.

4. Install the Disc Brake Components Begin by mounting the new rotor onto the hub. Ensure it's aligned properly and secure it using the provided hardware. Next, install the caliper bracket to the knuckle, following the instructions provided in your conversion kit.

5. Attach the Caliper and Brake Pads Once the bracket is in place, you can attach the caliper, ensuring that it fits snugly over the rotor. Insert the new brake pads into the caliper, ensuring they are properly positioned.

6. Upgrade Brake Lines (if necessary) Depending on your vehicle and the conversion kit, you may need to replace the existing brake lines with new ones designed for disc brakes. Be sure to use appropriate fittings and connectors.

7. Bleed the Brakes After everything is installed, it's necessary to bleed the brake system to remove any air. Start by filling the brake master cylinder with fresh brake fluid. Then, using a helper or a brake bleeder tool, work your way around each caliper, ensuring that fluid flows without bubbles.

8. Reinstall the Wheel and Lower the Vehicle Once the brakes are bled and working properly, reinstall the wheel. Hand-tighten the lug nuts before lowering the vehicle back to the ground. Once the car is on the ground, tighten the lug nuts to the manufacturer's specified torque.

9. Test Your Brakes Before driving, pump the brake pedal a few times to check for firmness. If everything feels good, take the car for a slow test drive to ensure that the brakes are functioning correctly.

Conclusion

Converting your drum brakes to rotors can enhance your vehicle's overall braking performance and reliability. By following these steps carefully and using the right tools, you can successfully complete the conversion. Always prioritize safety, and if you're unsure about any steps in the process, consult with a professional mechanic. With your new disc brakes, you'll enjoy improved stopping power and a more confident driving experience.
