How to Change Brake Drums to Rotors

Changing brake drums to rotors is a common upgrade for many vehicle owners looking to improve their vehicle's braking performance. While this process may seem daunting at first, with the right tools and knowledge, it can be accomplished by most DIY enthusiasts. This guide will walk you through the steps necessary to make the switch from brake drums to rotors.

Understanding the Difference

Before diving into the process, it's essential to understand the difference between brake drums and rotors. Brake drums are typically found in older vehicles and are part of a drum braking system. When the brake pedal is engaged, brake shoes expand against the inside of the drum to create friction, slowing the vehicle down.

On the other hand, brake rotors are part of a disc braking system, which is more efficient and offers better heat dissipation. Disc brakes use calipers and brake pads to squeeze the rotor, creating friction. This system generally provides better stopping power and shorter stopping distances, particularly under heavy braking conditions.

Tools and Materials Needed

To change from brake drums to rotors, you'll need the following tools and materials

- Jack and jack stands - Lug wrench - Brake cleaner - Socket set and ratchet - Screwdrivers (flathead and Phillips) - C-clamp or brake caliper tool - Brake pads - Brake rotors - New hardware (if needed)

Step-by-Step Process

1. Preparation Park your vehicle on a flat surface, turn on the hazard lights, and engage the parking brake. Gather all necessary tools and materials.

2. Remove the Wheel Use a lug wrench to loosen the lug nuts before raising the vehicle with a jack. Once the vehicle is safely elevated, completely remove the lug nuts and take off the wheel to expose the brake assembly.

3. Remove the Brake Drum If your vehicle currently has brake drums, locate the retaining screws and remove them. Slide the drum off the wheel hub. If it’s stuck, tap it gently with a rubber mallet to free it.

4. Inspect Components Before installing the rotors, inspect the brake shoes and other components. Replace any worn parts as necessary.

5. Remove Brake Shoes To switch to rotors, you'll need to remove the existing brake shoes. Take note of how everything is assembled or take a photo for reference. Remove the springs and other components carefully.

6. Install New Hardware If you're upgrading to rotors, you might need to install a new backing plate or other hardware specific to disc brakes. Follow the manufacturer's instructions.

7. Install Brake Rotors Place the new rotors onto the hub. Ensure they fit securely and flush against the mounting surface.

8. Attach Brake Calipers Next, you'll need to install the brake calipers. Position the caliper over the rotor and secure it using the hardware supplied. Make sure the calipers move freely.

9. Install Brake Pads Insert the new brake pads into the caliper bracket. Ensure they are positioned correctly for even wear and optimal performance.

10. Reattach the Wheel Place the wheel back onto the hub and hand-tighten the lug nuts. Lower the vehicle and then tighten the lug nuts in a crisscross pattern to ensure even pressure.

11. Test Your Brakes Before taking your vehicle on the road, pump the brake pedal a few times to seat the brake pads against the rotors. Check for any fluid leaks and ensure everything is functioning correctly.

Conclusion

Switching from brake drums to rotors can enhance your vehicle's braking performance and safety. While the process requires some mechanical knowledge and tools, it can be a rewarding DIY project. Always prioritize safety by using jack stands and ensuring that all components are securely fitted. If you feel unsure about any stage of the process, consulting with a professional mechanic is always a wise choice. Enjoy your improved braking system!
