How to Change Drum Brakes to Disk Brakes

Upgrading from drum brakes to disc brakes can significantly improve your vehicle's performance, providing better stopping power and reducing brake fade. While the process can be challenging, with the right tools and knowledge, it can be accomplished in a few steps. Here’s a guide on how to change drum brakes to disc brakes.

Understanding the Difference

Before diving into the conversion process, it’s essential to understand the differences between drum and disc brakes. Drum brakes consist of a set of shoes that push against a curved drum to create friction, while disc brakes use a set of pads that clamp down on a flat rotor. Disc brakes tend to dissipate heat better, which means they provide more consistent performance, especially under heavy braking conditions.

Tools and Materials Needed

To begin, gather the necessary tools and parts

- Socket set and wrenches - Jack and jack stands - Brake cleaner - Brake grease - New disc brake conversion kit (this may include rotors, calipers, brake pads, and hardware) - Brake fluid - Torque wrench - Screwdrivers

Step 1 Prepare the Vehicle

1. Safety First Park your vehicle on a flat surface, engage the parking brake, and wear appropriate safety gear. 2. Lift the Vehicle Use a jack to lift the vehicle and secure it with jack stands. Remove the wheels to access the brake assembly.

Step 2 Remove the Drum Brakes

1. Disassemble the Drum Assembly Start by removing the retaining clips and the wheel cylinder. Carefully take off the drum by sliding it off the backing plate. 2. Remove the Brake Shoes Disconnect the springs and any other hardware holding the brake shoes in place. Note how the assembly is configured for reinstallation reference.

Step 3 Install the Disc Brake Kit

1. Attach the New Bracket Most disc brake conversion kits come with a new mounting bracket. Secure the bracket to the spindle according to the manufacturer’s instructions. 2. Install the Rotors Slide the new disc rotors onto the hub. Ensure they fit snugly against the mounting surface. 3. Mount the Calipers Attach the calipers to the new bracket, ensuring they are properly aligned with the rotors. Don’t forget to double-check the placement of the caliper components.

Step 4 Connect the Brake Lines

1. Install the Brake Lines If your kit includes new brake lines, replace the old lines with the new ones. Be cautious not to cross-thread any fittings. Tighten them securely but avoid over-tightening. 2. Bleed the Brakes After ensuring all connections are secure, it’s crucial to bleed the brake lines to remove any air bubbles. Start from the caliper farthest from the master cylinder and work your way toward it.

Step 5 Reassemble and Test

1. Reinstall the Wheels Once everything is secure, put the wheels back on and lower the vehicle. 2. Test the Brakes Before driving, press the brake pedal several times to allow the calipers to clamp onto the rotors. Check for any leaks and make sure the brake pedal feels firm.

Conclusion

Converting drum brakes to disc brakes is a worthwhile upgrade that can enhance your vehicle's performance and safety. While the process requires some mechanical savvy and the right tools, it is manageable for those with a bit of experience. Always consult with a professional if you’re unsure about any step in the process, as brakes are critical for vehicle safety. Happy upgrading!
