Steps for Upgrading Your Vehicle from Drum Brakes to More Efficient Disc Brakes

How to Swap Drum Brakes for Disc Brakes

Upgrading your vehicle from drum brakes to disc brakes can significantly enhance braking performance and safety. While drum brakes are effective, disc brakes generally offer better stopping power, quicker cooling, and reduced chances of brake fade. If you're considering this upgrade, this guide will walk you through the necessary steps to successfully swap drum brakes for disc brakes.

Step 1 Gather Your Tools and Parts

Before you begin the installation process, ensure you have all the necessary tools and parts. You'll need

- A complete disc brake conversion kit (including calipers, rotors, and brackets) - Brake lines - Brake fluid - A jack and jack stands - Wrenches and sockets - A brake bleeder kit - A screwdriver - Safety glasses and gloves

Make sure the conversion kit is compatible with your vehicle’s make and model to avoid any complications.

Step 2 Safety First

Always prioritize safety. Park your vehicle on a level surface, engage the parking brake, and wear safety gear. Use the jack to lift your vehicle and secure it with jack stands. This will provide you with plenty of room to work under the car.

Step 3 Remove the Rear Wheels

Start by removing the rear wheels to access the drum brake assembly. Use a wrench to loosen the lug nuts before you lift the vehicle and remove the wheels completely.

Step 4 Take Off the Drum Brake Assembly

Once the wheels are off, locate the drum brakes. You'll need to remove the brake drum itself. Use a screwdriver to pry off any dust covers. Then, remove the retaining screws, if there are any. Carefully slide the drum off to reveal the brake shoes and other components.

Step 5 Detach the Brake Components

After removing the drum, disconnect the brake shoes, springs, and any other components attached to the drum assembly. Take note of their arrangement; this will help when you install the new disc brakes. It may be helpful to take pictures during this process.

Step 6 Install the Disc Brake Components

Now it's time to install your new disc brake kit. Begin by mounting the caliper brackets to the rear axle where the drum brakes were previously installed. Make sure to follow the manufacturer's instructions regarding the orientation and torque specifications.

Next, slide the rotor onto the wheel hub. If your kit includes new bearings or seals, be sure to install them during this step. With the rotor in place, you can attach the calipers to the brackets. Ensure they move freely and align with the rotor.

Step 7 Install New Brake Lines

Drum brakes typically use different brake lines than disc brakes. As a result, you will need to replace them with new lines that are compatible with your disc brake setup. Follow the kit's instructions for routing and securing the lines, ensuring there are no kinks and that they are properly secured away from any moving parts.

Step 8 Bleed the Brakes

Once everything is in place, it's crucial to bleed the brake system to eliminate air bubbles. Use a brake bleeder kit to do this start with the farthest brake from the master cylinder and work your way closer. Have an assistant pump the brake pedal while you open and close the bleeder valve on each caliper. Keep an eye on the brake fluid levels and add fluid as necessary.

Step 9 Reinstall the Wheels and Test Drive

Finally, replace the rear wheels, tightening the lug nuts in a star pattern to ensure even pressure. Lower your vehicle and take a moment to double-check everything visually.

Before taking your vehicle for a test drive, gently pump the brakes to ensure they engage properly. Start with low-speed stops to break in the new brakes. Pay attention to any unusual noises or vibrations and address issues promptly.

Conclusion

Swapping drum brakes for disc brakes can significantly improve your vehicle's braking efficiency. While this process requires some mechanical skill, following these steps can lead to a successful upgrade. Enjoy the added performance and safety that comes with your new disc brakes!
