Upgrading Rear Drum Brakes to Disc A Comprehensive Guide for Better Performance

Converting Rear Drum Brakes to Disc A Comprehensive Guide

When it comes to enhancing the performance of your vehicle, one of the most significant upgrades you can consider is converting your rear drum brakes to disc brakes. This modification not only improves stopping power but also offers better heat dissipation, reduced weight, and overall improved handling. In this article, we'll explore the reasons for this conversion, the benefits it brings, and a step-by-step guide to help you through the process.

Why Consider a Conversion?

1. Increased Stopping Power Disc brakes provide superior stopping power compared to drum brakes. The design of disc brakes allows for better contact with the rotor, which translates into more effective braking.

2. Heat Dissipation Drum brakes can overheat, leading to brake fade, especially during extensive usage such as in performance driving or hauling heavy loads. Disc brakes are better at dissipating heat, maintaining consistent performance even under stress.

3. Maintenance and Longevity Disc brakes are generally easier to maintain and have a longer lifespan than drum brakes. The open design allows for easier inspection and cleaning, while the components are less susceptible to moisture and dirt accumulation.

4. Enhanced Performance For many enthusiasts, the performance benefits of switching to disc brakes can improve the overall driving experience. Better modulation and responsiveness can be felt, especially during spirited driving or track days.

What You'll Need for the Conversion

Before diving into the conversion process, gather the necessary tools and components. Here’s a checklist of what you’ll typically need

- Disc brake conversion kit Available from aftermarket suppliers and often includes new rotors, calipers, pads, and mounting hardware. - Brake lines You may need to replace or modify the existing brake lines to accommodate the new disc brake setup. - Tools A jack, jack stands, wrenches, socket sets, and possibly a pulley tool for hub removal. - Safety Equipment Always wear gloves and safety goggles when working on your vehicle.

Step-by-Step Guide

Step 1 Prepare Your Vehicle

Before starting, park your vehicle on a level surface, engage the parking brake, and loosen the lug nuts on the rear wheels. Lift the vehicle using a jack and secure it on jack stands. Remove the rear wheels.

Next, you'll need to dismantle the existing drum brakes. Start by removing the brake drums, which may require some gentle tapping to loosen rust. Take note of how the components are assembled for reference during reinstallation.

Step 3 Install the New Disc Brake Components

Follow the instructions provided in your disc brake conversion kit

- Attach the new brake backing plates, ensuring they are securely fastened. - Install the rotors on the new backing plates. - Mount the calipers onto the new backing plates, ensuring they are positioned correctly.

Make sure all components are aligned and securely attached.

Step 4 Modify Brake Lines

You may need to modify or replace your brake lines to fit the new system. Ensure that all lines are securely fastened and free of leaks. If you're unsure about making these modifications, consult a professional.

Step 5 Bleed the Brakes

Once everything is in place, it’s crucial to bleed the brake system to remove any air that may have entered. Start from the wheel farthest from the master cylinder and work your way to the closest. Use a brake bleeder tool or pump the brake pedal to force the fluid through until all air bubbles escape.

Step 6 Test Drive and Adjust

Before hitting the road, double-check all components to ensure everything is secured properly. Once you've completed the checks, take your vehicle for a cautious test drive. Pay attention to how the brakes feel and make any necessary adjustments.

Conclusion

Converting rear drum brakes to disc brakes can significantly enhance your vehicle’s braking performance, safety, and reliability. While the process may seem daunting, with the right tools and patience, it can be a rewarding project that improves your driving experience. Always prioritize safety and don't hesitate to consult with professionals if you're unsure during any step of the conversion. Enjoy the enhanced performance and feel the difference the next time you hit the road!
