How to Convert from Drum Brakes to Disc Brakes

Upgrading your vehicle's braking system is a significant improvement that can enhance performance, safety, and aesthetics. Converting from drum brakes to disc brakes is a popular modification among automotive enthusiasts, as disc brakes generally offer better stopping power and heat dissipation. In this guide, we will walk you through the steps to successfully convert drum brakes to disc brakes.

Understanding the Differences

Before diving into the conversion process, it’s vital to understand the differences between drum and disc brakes. Drum brakes consist of a cylindrical drum that rotates with the wheel, utilizing brake shoes that press outward against the drum’s inner surface. This setup can lead to brake fade due to overheating. In contrast, disc brakes use a rotor and caliper system, where brake pads clamp down on the rotor to create stopping force. This arrangement provides superior heat dissipation and generally results in better performance.

Materials Needed

Before starting your conversion, gather the necessary tools and materials. Common items include

1. Disc brake conversion kit Available for most vehicle makes and models; it typically contains the rotors, calipers, pads, and brackets needed. 2. Brake lines New lines may be required to accommodate the calipers. 3. Tools Wrenches, sockets, brake fluid, jack stands, and a floor jack. 4. Safety gear Gloves and goggles should be worn throughout the process.

Step-by-Step Conversion Process

1. Preparation

Begin by ensuring your vehicle is parked on a level surface, and engage the parking brake. Wear your safety gear to protect yourself during the conversion.

2. Remove the Wheel

Using a jack and jack stands, lift the vehicle and securely support it. Remove the wheel to expose the drum brake assembly.

3. Remove the Drum Brakes

Detach the drum by removing the retaining screws or the drum’s retaining clips. Once loose, carefully slide the drum off, exposing the brake shoes and hardware. Take note of how everything is assembled, as this can help during reinstallation.

4. Detach the Brake Hardware

Remove the brake shoes and any associated hardware, including the springs and adjusters. Be cautious, as the springs can be under tension.

5. Install the Disc Brake Components

Now it’s time to install the new disc brake components

- Attach the new brake bracket to the spindle as per the instructions in your conversion kit. - Install the rotors onto the hub. Ensure that they are seated properly and torque the retaining nuts or bolts as per manufacturer specifications. 6. Attach the Calipers

Mount the new calipers onto the brackets and install the brake pads according to the instructions that came with your conversion kit. Ensure that the calipers can move freely and that everything aligns correctly.

7. Replace Brake Lines

Depending on your conversion kit, you may need to replace the existing brake lines to fit the new calipers. Ensure there are no leaks after installation.

8. Fill and Bleed the Brake System

Refill the brake fluid reservoir with the recommended fluid. Proceed to bleed the brake system to remove any air bubbles. This step is crucial for proper brake function.

9. Reinstall the Wheel

After confirming that everything is properly installed and torqued, reinstall the wheel. Lower the vehicle from the jack stands and give the brake pedal a few presses to seat the pads against the rotors.

Final Checks

Before taking your vehicle on the road, conduct a series of tests in a safe area. Check for unusual noises, and monitor brake responsiveness. Ensure that the stopping power meets your expectations.

Conclusion

Converting from drum brakes to disc brakes can significantly enhance your vehicle's braking performance. While the process requires attention to detail and proper tools, the upgrade is well worth the effort. Whether you are looking for improved safety or simply aiming to upgrade your ride, this conversion can achieve your goals efficiently. Remember always to consult your vehicle’s manual and consider seeking professional help if needed. Happy driving!
