How to Convert Brake Drum to Disc Brakes

Converting brake drums to disc brakes can significantly improve your vehicle's braking performance, steering control, and heat dissipation. While this process might seem daunting, with the right tools, knowledge, and patience, it can be accomplished even by those with moderate mechanical skills. This article will guide you through the steps, tools required, and considerations for converting your drum brakes to disc brakes.

Why Convert to Disc Brakes?

Disc brakes provide several advantages over drum brakes

1. Improved Stopping Power Disc brakes typically offer better stopping power due to their larger surface area. They can handle greater heat, which reduces the risk of brake fade during prolonged use.

2. Faster Cooling The open design of disc brakes allows for better airflow, resulting in superior heat dissipation. This is particularly beneficial during heavy braking or in hilly terrain.

3. Easier Maintenance Disc brakes are generally easier to service. Brake pads can be replaced quickly without the hassle of dealing with the internal components typically found in drum brakes.

4. Better Performance in Wet Conditions Disc brakes shed water more effectively than drum brakes, resulting in improved stopping power in rainy conditions.

Tools and Materials Required

Before starting the conversion, ensure you have the following tools and materials

- Jack and jack stands - Lug wrench - Socket wrench set - Brake cleaner - Brake pads and calipers (specific to your vehicle make/model) - Disc rotors - Brake lines (if necessary for the new calipers) - Hardware kit (bracket mounts and hoses) - Torque wrench - Safety goggles and gloves

1. Prepare the Vehicle Start by safely lifting the vehicle with a jack and securing it with jack stands. Remove the rear wheels to access the drum brakes.

2. Remove the Drum Brakes Take off the brake drum by removing the retaining screws. You may need to tap it gently to loosen any corrosion. Once removed, detach the brake shoes, springs, and hardware.

3. Install the Brake Caliper Bracket Depending on the conversion kit you selected, you may need to install a bracket to hold the caliper in place. Follow the instructions from the conversion kit and ensure it is properly secured.

4. Attach the Caliper Install the disc brake caliper to the bracket. Make sure to apply any necessary grease to the caliper slides to ensure smooth operation.

5. Install the Disc Rotors Slip the new disc rotors onto the hub. Align them carefully and secure them according to the manufacturer's specifications.

6. Replace Brake Lines If your kit recommends new brake lines, this is the time to install them. Ensure there are no leaks by checking all connections.

7. Install Brake Pads Slide the new brake pads into place within the caliper. Ensure they are appropriately seated and free from any obstructions.

8. Bleed the Brake System Once everything is installed, it is crucial to bleed the brake system to remove any air trapped in the lines. This ensures effective braking performance.

9. Reinstall Wheels and Lower the Vehicle Put the wheels back on and secure them with lug nuts. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.

10. Test Drive Before hitting the road, test the brakes at low speed in a safe area to ensure they are functioning correctly. Check for any unusual noises or vibrations.

Conclusion

Converting from drum to disc brakes can enhance your vehicle's braking efficiency significantly. While this guide outlines the essential steps and considerations, remember that specific vehicles may require additional parts or procedures. Always consult professional manuals or a skilled mechanic if uncertain. Enjoy your improved braking performance and stay safe on the road!
