Converting Brake Drums to Rear Discs A Comprehensive Guide
Upgrading your vehicle's braking system from rear drum brakes to disc brakes can significantly enhance overall performance, safety, and driving experience. While drum brakes have been a common sight in vehicles for decades, disc brakes offer numerous advantages that make them a preferred choice for modern cars. In this article, we’ll explore the reasons for this conversion, the benefits of rear disc brakes, and a basic overview of the conversion process.
Why Convert to Rear Disc Brakes?
1. Improved Stopping Power Disc brakes generally provide better stopping power than drum brakes. This is particularly true in high-performance situations, such as during sudden stops or aggressive driving. The increased surface area of the brake pads against the disc enables more effective heat dissipation, resulting in superior braking performance.
2. Heat Management Rear drum brakes can overheat during extended use, leading to brake fade, which is a reduction in stopping power due to temperature. Disc brakes dissipate heat more efficiently, reducing the risk of fade and maintaining consistent performance even under heavy use.
3. Maintenance Disc brakes are generally easier to maintain than drum brakes. With drum brakes, the components are enclosed, making inspection and servicing cumbersome. Disk brake systems are more accessible, allowing for quicker inspections, repairs, and replacements.
4. Better Wet Weather Performance Disc brakes tend to perform better in wet conditions. They are less prone to water accumulation since they are exposed to the elements, which improves their stopping power in rainy conditions.
Benefits of Rear Disc Brakes
1. Enhanced Safety The combination of better stopping power and heat management results in increased safety. Enhanced braking performance is crucial in avoiding collisions and managing emergency situations.
2. Better Driving Experience The consistent performance of disc brakes contributes to a smoother driving experience. The more precise nature of disc brakes offers improved pedal feel and responsiveness.
3. Resale Value A vehicle equipped with a modern braking system can have higher resale value. Potential buyers are often willing to pay more for vehicles that have been properly upgraded and maintain high safety standards.
Conversion Process Overview
Converting rear drum brakes to disc brakes involves several steps, which may vary depending on the make and model of the vehicle. Here’s a simplified outline of the process
1. Research and Purchase Start by researching the specific parts needed for your vehicle. There are kits available that include everything from the calipers and pads to the rotors and mounting hardware. Ensure that the parts are compatible with your vehicle model.
2. Remove Existing Drum Brakes Lift the rear of the vehicle and remove the wheels. Then, detach the drum brake assembly, which includes the drum, shoes, and associated hardware.
3. Install the Disc Brake Kit Follow the instructions provided with your disc brake kit. This typically involves installing the new rotor onto the hub, attaching the caliper bracket, and fitting the caliper with new brake pads.
4. Connect Brake Lines Ensure that the brake lines are connected properly and check for any leaks.
5. Test the System Before hitting the road, pump the brake pedal to ensure the system is pressurized and perform a thorough test in a safe area to confirm proper functionality.
Conclusion
Converting from rear drum brakes to disc brakes can be a rewarding enhancement to your vehicle. Not only does it improve safety and performance, but it also provides a better driving experience. With careful research and the right tools, this upgrade can be completed efficiently, offering long-term benefits every time you hit the road.
