Upgrading Rear Brakes from Drum to Disc with a Conversion Kit

Upgrading Your Rear Brakes The Benefits of Converting from Drum to Disc with a Conversion Kit

When it comes to automotive performance, few components are as critical as the braking system. For many vehicles, especially older models, the rear brakes may consist of drum brakes. While drum brakes have served their purpose for decades, there’s a significant advantage to upgrading to disc brakes. This article explores the benefits of converting from drum to disc brakes using a rear brake conversion kit, the installation process, and considerations to keep in mind.

Understanding Drum vs. Disc Brakes

Before diving into the advantages of a conversion kit, it's essential to understand the fundamental differences between drum and disc brakes. Drum brakes operate by pushing brake shoes against the inside of a spinning drum to create friction. While they can handle significant braking loads, they tend to have several drawbacks, including heat buildup and less effective performance in wet conditions.

In contrast, disc brakes consist of a rotor that spins with the wheel, and calipers with brake pads that clamp onto the rotor to generate stopping power. Disc brakes typically provide better heat dissipation, more consistent performance, and improved stopping power, especially in high-performance situations or adverse weather conditions.

Benefits of Rear Brake Conversion Kits

1. Improved Stopping Power One of the most significant advantages of converting to a disc brake system is the enhanced stopping power. Disc brakes are more responsive and provide better performance under heavy braking. This improvement is critical, especially for performance vehicles and those who regularly carry heavy loads or tow trailers.

2. Enhanced Heat Dissipation Drum brakes can suffer from brake fade due to overheating during prolonged use. Disc brakes, with their open design, dissipate heat more effectively, reducing the risk of fade and maintaining braking performance even under strenuous conditions.

3. Better Performance in Wet Conditions Drum brakes tend to retain water, which can lead to reduced braking efficiency in wet conditions. Disc brakes provide better initial brake response and modulation, ensuring that drivers have better control even when the roads are slick.

4. Reduced Maintenance Drum brakes often require more frequent adjustments and maintenance. Conversely, disc brakes typically have a longer lifespan and require fewer adjustments, resulting in lower long-term maintenance costs.

5. Aesthetic Appeal While performance is the main driver for many, the visual appeal of disc brakes should not be overlooked. Many enthusiasts appreciate the cleaner, more modern look of disc brakes, which can add to the overall aesthetics of the vehicle.

Installation Process

Installing a rear brake conversion kit can seem daunting, but with the right tools and instructions, it is achievable for most DIY mechanics

. Here are the general steps involved

1. Gather Your Tools and Materials Ensure you have a complete rear brake conversion kit for your specific vehicle model, along with standard tools like wrenches, sockets, and possibly a brake line tool.

2. Remove the Existing Drum Brakes Safely lift the vehicle using jack stands, and remove the rear wheels. Carefully remove the drum brakes, following your vehicle’s service manual for specific instructions.

3. Install the New Disc Brake Components Follow the conversion kit instructions to install the new rotors, calipers, and brake pads. Ensure all components are securely fastened and properly aligned.

4. Bleed the Brake Lines After installation, it’s crucial to bleed the brake lines to eliminate any air bubbles that can reduce brake performance.

5. Test the Brakes Before hitting the road, conduct a thorough brake check. Ensure everything is functioning correctly and that you have solid pedal feel.

Considerations Before Conversion

While the benefits of converting from drum to disc brakes are plentiful, there are a few considerations to keep in mind. Some vehicles may require additional modifications, such as changes to the rear axle or brake lines. It’s also essential to ensure that the new brake system is compatible with your vehicle’s overall braking system, including the master cylinder.

Conclusion

Upgrading from drum brakes to disc brakes with a conversion kit can significantly enhance your vehicle's safety and performance. While the initial investment may seem substantial, the long-term benefits, including improved stopping power, reduced maintenance, and better performance in various conditions, make it a worthwhile upgrade for any vehicle owner. Whether you're a daily driver or a performance enthusiast, a rear brake conversion is a step towards a safer and more reliable driving experience.
