Upgrading Your Vehicle from Drum Brakes to Disc Brakes Made Easy

How to Change from Drum Brakes to Disc Brakes

Upgrading your vehicle's braking system from drum brakes to disc brakes is a common modification that can enhance performance, safety, and reliability. This guide outlines the steps you need to take to make this conversion, along with considerations and benefits of switching to disc brakes.

Understanding Brake Systems

Drum brakes have been used for decades, typically found on older vehicles and many economy models. While effective, they have limitations, particularly regarding heat dissipation, which can lead to brake fade during prolonged use. Disc brakes, on the other hand, provide superior stopping power and performance thanks to better heat management and a design that enhances the vehicle's handling characteristics.

Benefits of Converting to Disc Brakes

1. Improved Performance Disc brakes tend to offer more consistent stopping power under heavy load or extended braking conditions. 2. Less Maintenance Disc brakes are typically easier to service and replace than drum brakes. 3. Enhanced Safety The immediate response and reliability of disc brakes contribute to overall vehicle safety. 4. Aesthetic Appeal Disc brakes often look more modern and can enhance the visual appeal of your vehicle.

Tools and Materials Needed

Before you begin, gather the necessary tools and materials

- Socket wrench set - Torque wrench - Screwdrivers (flat and Phillips) - Brake cleaner - New disc brake conversion kit (rotors, calipers, brake pads, and hardware) - Brake fluid - Jack and jack stands - Safety glasses and gloves

Step-by-Step Conversion Process

1. Preparation

- Safety First Ensure the vehicle is parked on a flat surface, and engage the parking brake. Wear safety glasses and gloves for protection. - Lift the Vehicle Use a jack to raise the vehicle and secure it on jack stands.

2. Remove the Wheels

- Take off the lug nuts and remove the wheels to expose the brake components.

3. Remove Drum Brakes

- Disconnect the Brake Components Remove the brake lines if necessary and detach any retaining springs or clips. - Take Off the Drum Slide the drum off the hub. You may need to tap it lightly with a hammer if it’s stuck. - Remove Shoes If the shoes are still attached to the drum, remove them along with the hardware.

4. Install the Disc Brake Kit

- Mount the Spindle If your conversion kit requires it, you may need to replace the spindle. - Install Caliper Brackets Follow the manufacturer’s instructions to attach the caliper brackets. - Install Rotors Slide the new rotors onto the hub. Make sure they are secure and properly aligned.

5. Attach Calipers

- Install Calipers Attach the new calipers to the brackets, ensuring they are oriented correctly and tightened to the manufacturer’s specifications. - Add Brake Pads Insert the new brake pads into the calipers.

6. Connect Brake Lines

- Connect the brake lines to the new calipers. Ensure there are no leaks and that everything is tightened securely.

7. Refill Brake Fluid

- Bleed the Brakes Fill the brake fluid reservoir and bleed the brake lines to remove any air trapped in the system. - Check for Leaks Inspect all connections for leaks and tighten them as necessary.

8. Reassemble and Test

- Reinstall the wheels and lug nuts. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications. - Test Drive Carefully test the brakes at low speed to ensure they’re functioning correctly before pushing them to their limits.

Conclusion

Converting from drum brakes to disc brakes can significantly improve your vehicle's performance and safety. While the process requires some mechanical skill and the right tools, it can be a rewarding endeavor that enhances your driving experience. Always refer to your vehicle's service manual for specific instructions related to your make and model. If you’re unsure or uncomfortable with any step, consulting a professional mechanic is advisable to ensure proper installation and safety.
