How to Replace Drum Brakes with Disk Brakes

Upgrading from drum brakes to disc brakes can significantly enhance your vehicle's stopping power and performance. This transition is especially beneficial for older cars, as drum brakes may not provide the necessary efficiency and heat dissipation seen in modern disc brake systems. Here’s a comprehensive guide on how to replace drum brakes with disc brakes.

Why Upgrade from Drum to Disc Brakes?

Disc brakes generally offer superior performance compared to drum brakes. They provide better heat dissipation, which reduces the risk of brake fade during prolonged use. Additionally, disc brakes typically have a more consistent response and require less maintenance over time. Upgrading to disc brakes can enhance driving safety and improve the overall driving experience.

Tools and Materials Required

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

- Jack and jack stands - Lug wrench - Brake cleaner - Wrench set - Screwdrivers - New disc brake rotors and pads - Brake calipers (if required) - Brake lines (as necessary) - Anti-seize lubricant - Torque wrench

Step-by-Step Guide

1. Safety First Park your vehicle on a flat surface and set the parking brake. Before you start working on the brakes, wear safety glasses and gloves to protect yourself from debris and chemicals.

2. Raise the Vehicle Use a jack to lift the rear or front of the vehicle, depending on which brake system you are replacing. Secure the vehicle with jack stands to ensure stability.

3. Remove the Wheel Use a lug wrench to loosen and remove the lug nuts, then take off the wheel to access the drum brake assembly.

4. Remove the Drum Brake Assembly - Locate the drum brake. There should be a retaining mechanism, usually in the form of screws or clips, holding the drum in place. - Remove these clips or screws, and gently pull the drum off. If the drum is difficult to remove, tap it lightly with a mallet, ensuring you do not damage any components.

5. Detach the Brake Components - Disconnect the brake line from the wheel cylinder. - Remove the brake shoes and any associated springs. Note how everything is configured, as this will be useful when installing the new disc brake components.

6. Install New Brake Lines (If Required) If your new disc brake system requires different brake lines, replace them now before moving to the rotor installation.

7. Install Disc Brake Rotors - Mount the new brake rotor onto the hub. Ensure it is properly seated and secured. - Use anti-seize lubricant on the rotor hub area to prevent rust and make future maintenance easier.

8. Attach the Caliper - Install the new brake caliper over the rotor. If you’re using new calipers, follow the manufacturer's instructions for any specific assembly requirements. - Attach the caliper using the bolts provided. Ensure they are properly torqued according to specifications to avoid loosening during use.

9. Insert New Brake Pads - Place the new brake pads into the caliper bracket. Make sure they are correctly aligned. - If your kit comes with shims or clips, install these as well for optimal brake performance.

10. Reconnect Brake Lines Reconnect any brake lines you may have detached during the process. Ensure there are no leaks at the connection points.

11. Repeat for the Other Side If you are replacing the brakes on both sides, repeat the entire process on the opposite side of the vehicle.

12. Reinstall Wheels Once both sides are complete, put the wheels back on, and hand-tighten the lug nuts. Lower the vehicle back to the ground, and then use a torque wrench to ensure all lug nuts are tightened to the manufacturer's specifications.

13. Bleed the Brakes Finally, it’s crucial to bleed the brake system to remove any trapped air. Begin with the brake furthest from the master cylinder and work your way closer.

14. Test the Brakes Before taking your vehicle for a drive, pump the brake pedal to ensure it feels firm. Check for any leaks and test the braking system in a safe area.

Conclusion

Replacing drum brakes with disc brakes is a rewarding project that can enhance your vehicle's safety and performance. While the process requires some mechanical knowledge and the right tools, it can be done with patience and precision. Always consult with a professional mechanic if you are unsure about any step in the process, and enjoy the improved braking capabilities of your vehicle!
