Converting Drum Brakes to Disc Brakes for Improved Performance and Safety

How to Change Drum Brakes into Disc Brakes

When it comes to upgrading the braking system of your vehicle, switching from drum brakes to disc brakes can offer significant advantages. Disc brakes typically provide better stopping power, enhance heat dissipation, and reduce brake fade. If you’re considering this upgrade, here’s a comprehensive guide on how to change drum brakes into disc brakes.

Step 1 Gather Necessary Tools and Parts

Before you begin, make sure you have all the tools and replacement parts at hand. You'll need

- New disc brakes specific to your vehicle model - Disc brake calipers - Brake pads - New rotors - Brake lines and fittings (if necessary) - Jack and jack stands - Wrenches and sockets - Brake fluid - Anti-seize lubricant - Torque wrench

Step 2 Safety First

Always prioritize safety when working on your vehicle. Begin by parking your car on a flat surface and engaging the parking brake. Loosen the lug nuts on the wheels you’ll be working on (typically the rear) before lifting the vehicle with a jack. Use jack stands to secure the vehicle before proceeding.

Step 3 Remove the Existing Drum Brakes

1. Take off the wheel Once the vehicle is securely lifted, remove the lug nuts completely and take off the wheel. 2. Remove the brake drum Depending on your vehicle, you might have to tap the drum with a hammer lightly to break it loose if it’s stuck. Once removed, you will see the brake shoes and other components.

3. Disassemble the drum brake components Take note of how everything is put together, as you’ll need to reference this when installing the new disc brakes. Remove the brake shoes, springs, and the backing plate if necessary. Be cautious as some components may be under tension.

Step 4 Install the New Disc Brake System

1. Install the new backing plate (if required) Some vehicles require a backing plate to be installed for disc brakes. Follow the manufacturer’s instructions for proper installation.

2. Attach the new caliper bracket Secure the caliper bracket to the new backing plate or the axle housing. Make sure to use the correct bolts and torque them to the specified values.

3. Install the new rotor Slide the new rotor onto the hub, ensuring that it sits flush and secure against the mounting surface.

Step 5 Install the Caliper and Brake Pads

1. Attach the caliper After the rotor is in place, install the caliper over it. The caliper should be positioned so that it can apply pressure directly onto the brake pads that will be placed later.

2. Insert brake pads Place the new brake pads into the caliper brackets. Make sure they fit snugly and are correctly aligned.

3. Secure the caliper Use the caliper bolts to secure it in place, making sure to torque them to the manufacturer's specifications.

Step 6 Connect Brake Lines

If your upgrade requires new brake lines, ensure they are properly connected and free of leaks. Bleed the brakes to remove any air from the system, which can compromise braking efficiency.

Step 7 Reinstall the Wheel and Test

Once everything is installed, replace the wheel and hand-tighten the lug nuts. Lower the vehicle back to the ground and tighten the lug nuts completely in a crisscross pattern to ensure even tightening.

Step 8 Final Adjustments and Testing

Before hitting the road, check for any leaks around the brake lines and make sure everything is secure. It’s essential to test the brakes in a safe area before normal driving conditions. Drive slowly and test the braking response to ensure that your new disc brake system is functioning correctly.

Conclusion

Upgrading from drum brakes to disc brakes can improve your vehicle's safety and performance. By following this detailed guide and ensuring attention to detail during the installation process, you’ll enjoy the enhanced braking capabilities of your new disc brakes. Remember, if you’re unsure at any step or feel uncomfortable performing this upgrade, it’s always wise to consult with a professional mechanic.
