How to Convert Drum Brakes to Disc Brakes in Your Vehicle

How to Change Drum Brakes to Disc Brakes

Converting drum brakes to disc brakes can significantly enhance a vehicle's braking performance, offering better heat dissipation, shorter stopping distances, and improved overall safety. While this process can be complex and labor-intensive, it can be a rewarding project for automotive enthusiasts. Here is a step-by-step guide on how to make this conversion.

Understand the Benefits

Before starting, it’s important to understand the advantages of disc brakes over drum brakes. Disc brakes generally provide better performance in wet conditions, as they are less prone to brake fade caused by heat build-up. They also require less maintenance, tend to provide more consistent braking performance, and are easier to inspect visually.

Gather the Necessary Tools and Parts

Before you begin the conversion, gather the appropriate tools and components. You'll need

1. Disc Brake Conversion Kit This typically includes new calipers, rotors, and brackets. Make sure it's compatible with your vehicle model. 2. Brake Lines You may need new brake lines to accommodate the different setup. 3. Brake Fluid Ensure you have the right type of brake fluid for your vehicle. 4. Basic Tools Wrenches, sockets, screwdrivers, and a jack with jack stands for safety. 5. Safety Gear Safety goggles and gloves to protect yourself during the process.

Prepare the Vehicle

1. Lift the Vehicle Use a jack to lift the vehicle and secure it with jack stands. Always ensure that the vehicle is stable before working underneath it. 2. Remove the Wheels Take off the lug nuts and remove the wheels to access the brakes.

Remove the Drum Brakes

1. Disconnect the Brake Lines Carefully detach the brake lines from the drum brake assembly. Be prepared for some brake fluid to leak. 2. Take off the Drum Remove any retaining clips, then pull the drum off. You might need to gently tap it if it's stuck due to rust. 3. Remove Components Take off the brake shoes, wheel cylinder, and any other components that are part of the drum brake assembly.

Install the Disc Brake Components

1. Attach the Caliper Bracket Follow the instructions provided with your conversion kit to install the caliper bracket onto the spindle. 2. Install the Rotor Slide the disc rotor onto the hub and secure it in place. 3. Mount the Caliper Place the caliper over the rotor and secure it according to the kit’s specifications. Ensure it moves freely and aligns correctly. 4. Connect Brake Lines Route and install the new brake lines as specified, ensuring there are no kinks or sharp bends.

Refill and Bleed the Brake System

1. Add Brake Fluid Fill the master cylinder with the appropriate brake fluid. 2. Bleed the Brakes This is crucial to remove any air from the brake lines. Start at the wheel farthest from the master cylinder and work your way forward, using a brake bleeder kit or having an assistant pump the brakes while you open and close the bleeder valve.

Reassemble and Test

1. Reinstall the Wheels Once everything is in place and you’re satisfied with the installation, put the wheels back on and tighten the lug nuts. 2. Lower the Vehicle Carefully lower the vehicle back to the ground. 3. Test the Brakes Before driving, pump the brake pedal a few times to ensure the caliper pads are seated properly against the rotors. Check for any leaks and test the brakes at low speeds in a safe area.

Conclusion

Converting drum brakes to disc brakes involves a detailed understanding of your vehicle’s brake system, along with careful execution of each step. While this conversion presents a greater initial investment and time commitment, the resulting improvement in brake performance can be well worth the effort. Always consider seeking professional assistance if you feel unsure at any point during the conversion. Drive safely!
