Steps to Upgrade Rear Drum Brakes to Disc Brakes for Improved Performance

Converting Rear Drums to Disc Brakes A Step-by-Step Guide

Upgrading your vehicle's braking system can significantly enhance its performance and safety. One popular modification among car enthusiasts is converting rear drum brakes to disc brakes. Unlike drum brakes, disc brakes offer improved stopping power, better heat dissipation, and increased resistance to brake fade. If you're considering making this upgrade, here's a comprehensive guide on how to convert rear drums to disc brakes.

Why Consider the Upgrade?

1. Increased Performance Disc brakes generally provide better stopping power due to their larger surface area and improved heat dissipation. 2. Heat Management Disc brakes cool down more quickly than drum brakes, helping to prevent brake fade during heavy use. 3. Maintenance Disc brakes are usually easier to maintain and replace, as they have fewer moving parts and are more accessible.

Tools and Materials Needed

Before you begin the conversion process, gather the following tools and materials

- Brake conversion kit (specific to your vehicle model) - Basic hand tools (wrench set, socket set, screwdrivers) - Brake fluid - Jack and jack stands - Wire brush - New brake pads (if necessary) - Safety glasses and gloves

1. Research and Purchase a Conversion Kit The first step is to find a conversion kit specifically designed for your vehicle. These kits generally include all necessary components, such as calipers, rotors, brackets, and hoses. Ensure the kit is compatible with the make and model of your car.

2. Prepare Your Vehicle Park your vehicle on a level surface and ensure it’s in gear or the parking brake is engaged. Loosen the lug nuts on the rear wheels but do not remove them yet. Use the jack to lift the rear of the car and secure it with jack stands for safety.

3. Remove the Rear Wheels Once the vehicle is safely lifted, remove the lug nuts and take off the rear wheels. This will give you access to the brake components.

4. Remove the Existing Drum Brakes Begin by taking off the drum brake assembly. This usually involves removing the drum, which may require a little persuasion with a hammer if it's stuck. Once the drum is off, disconnect the brake shoes, springs, and the wheel cylinder to fully remove the assembly.

5. Install the New Disc Brake Components Start by installing the new brake brackets in place of the old drum backing plate. Once fitted, mount the calipers and rotors according to the instructions provided in your conversion kit. Make sure everything is tightened securely.

6. Attach Brake Lines Connect the brake lines to the new calipers. If your conversion kit includes extended brake lines or flexible hoses, install them accordingly. Ensure there are no leaks in the system.

7. Reinstall the Wheels Once you have installed the calipers and rotors, put the wheels back on. Hand-tighten the lug nuts before lowering the vehicle back to the ground.

8. Bleed the Brakes With the vehicle on the ground, it’s essential to bleed the brake system to remove any air that may have entered during the installation. This will ensure optimal braking performance. Have a helper pump the brake pedal while you open the bleeder valves on the calipers, then close them once fluid runs out without bubbles.

9. Test the Brakes Before taking your vehicle back on the road, pump the brake pedal a few times to ensure the pads seat correctly against the rotors. Perform a cautious test drive at low speeds to ensure everything is functioning properly.

Conclusion

Converting rear drum brakes to disc brakes can be a rewarding project that improves your vehicle's performance and safety. While the process may require mechanical skill and patience, the end result is worth the effort. Always consult a professional if you’re unsure about any steps in the process, and remember that safety should always be your top priority when working on your vehicle's braking system.
