How to Swap Drum Brakes to Disc Brakes
Upgrading from drum brakes to disc brakes is a popular modification among car enthusiasts and performance-oriented drivers. Disc brakes offer better stopping power, improved heat dissipation, and reduced fade, making them a vital upgrade for those looking to enhance their vehicle’s braking system. Whether you’re upgrading for performance, safety, or aesthetics, this guide will walk you through the process step-by-step.
Understanding the Benefits
Before diving into the swap, it’s important to understand why many choose to upgrade to disc brakes. Disc brakes provide superior performance under high-stress conditions, such as aggressive driving, towing, or when driving in hilly terrains. They also generally allow for easier maintenance and replacement of components. The design of disc brakes helps in better heat dissipation, reducing the likelihood of brake fade during prolonged use.
Tools and Materials Needed
To successfully complete the brake conversion, you’ll need a variety of tools and parts
1. Tools - Jack and jack stands - Wrench set - Socket set - Brake bleeder kit - Screwdrivers - C-clamp - Brake cleaner
2. Parts - Disc brake rotors - Calipers (make sure to choose an appropriate size for your vehicle) - Brake pads - Brake lines (may need to upgrade from drum brake lines) - Mounting brackets - Hub assembly (if necessary)
Step-by-Step Process
1. Preparation Begin by safely raising your vehicle and removing the wheels. Ensure you're working on a flat, stable surface.
2. Remove Drum Brakes Take off the drum brake assembly. This usually involves removing the retaining springs and the brake drum itself. Be sure to take notes or pictures to help with reinstallation.
3. Install Mounting Brackets Depending on your vehicle model, you may need to attach new mounting brackets designed for disc brakes. These often come with your disc brake conversion kit.
4. Attach Calipers and Rotors Mount the disc brake rotors on the wheel hub. Next, attach the calipers over the rotors, ensuring that they align properly with the mounting brackets. Secure them using the provided bolts.
5. Install Brake Lines Replace the drum brake lines with those designed for disc brakes. Ensure that all connections are tight and leak-free. It may be necessary to install a proportioning valve to balance brake force.
6. Install Brake Pads Insert the brake pads into the calipers, ensuring they seat correctly. Use a C-clamp to compress the caliper pistons if necessary, allowing sufficient space for the new pads.
7. Bleed the Brakes Once everything is installed, bleed the brake lines to remove any air pockets. This can be done using a brake bleeder kit. Start from the brake farthest from the master cylinder and work toward the closest one.
Final Steps
After completing the installation, double-check all components for tightness and ensure everything is properly aligned. Reinstall the wheels and lower the vehicle back to the ground. Before taking your car out for a test drive, pump the brakes a few times to initialize the brake pads.
Conclusion
Swapping from drum brakes to disc brakes is a worthwhile upgrade that can vastly improve your vehicle’s braking capability. While it may require some mechanical knowledge and skill, following these detailed steps can help ensure a successful conversion. Always consult with a professional if you have any doubts, and enjoy the enhanced driving experience with your new disc brakes!
