How to Change Brake Drums to Rotors A Step-by-Step Guide
Upgrading from brake drums to disc rotors can enhance your vehicle's braking performance significantly. Disc brakes generally provide better stopping power, reduced fade, and easier maintenance compared to drum brakes. If you're considering making this switch, here’s a comprehensive guide to help you through the process.
Tools and Materials Needed
Before starting, gather the necessary tools and materials. You will need
- A jack and jack stands - Lug wrench - Brake cleaner - New disc rotors - New brake pads - Brake fluid - Torque wrench - Screwdriver - C-clamp or brake caliper tool - Safety glasses and gloves
Step 1 Safety First
Begin by ensuring your safety. Park your vehicle on a level surface, engage the parking brake, and wear safety glasses and gloves. This will protect you from any falling objects and keep your hands safe while working.
Step 2 Lift the Vehicle
Using a jack, raise the vehicle and secure it with jack stands. It is crucial to ensure the car is stable before proceeding with any work on the brakes. Loosen the lug nuts but don’t remove them until the wheel is off the ground.
Step 3 Remove the Wheels
Once the vehicle is securely elevated, remove the lug nuts entirely and take off the wheels. This will expose the brake assembly, making it easier to access the brake drums.
Step 4 Remove the Brake Drums
To remove the brake drums, look for any retaining screws or bolts. If your vehicle is equipped with these, take them out first. Then, carefully slide off the drum. If it is stuck due to rust or accumulated debris, gently tap it with a rubber mallet. Do not use excessive force; your goal is to avoid damaging other components.
Step 5 Remove the Old Brake Components
With the drum removed, you can now unbolt the brake shoes and other associated hardware. Take note of how everything is assembled, as you’ll need this information for reinstallation. It may be helpful to take pictures for reference.
Step 6 Install the New Components
Now it’s time to install the new disc brake assembly. First, install the new brake pads on the calipers. Use a C-clamp or brake caliper tool to compress the caliper piston for easier installation. Make sure everything is secure before moving on to attach the new rotors.
Step 7 Install the Brake Rotors
Slide the new rotors onto the wheel hub. Ensure they sit flush and align properly. If your rotors come with an installation guide, follow it carefully. Then, reattach any bolts or screws that secure the rotors in place.
Step 8 Reinstall the Calipers
Once the rotors are installed, you can now reinstall the brake calipers. Ensure that all bolts are tightened to the manufacturer’s recommended torque specifications. It’s essential to ensure everything is securely attached to avoid any issues while driving.
Step 9 Reinstall the Wheels
With the brake system in place, it’s time to put the wheels back on. Align them with the lug bolts and hand-tighten the nuts before lowering the vehicle. Once the car is back on the ground, use the torque wrench to tighten the lug nuts to the specified torque.
Step 10 Final Checks
Before driving, pump the brake pedal several times to seat the new pads against the rotors. Check the brake fluid levels and add fluid if necessary. Lastly, take your vehicle for a short test drive to ensure everything is functioning correctly.
Conclusion
Switching from brake drums to rotors can enhance your vehicle's braking abilities significantly. By following these steps methodically, you can ensure a successful upgrade. However, if you're not comfortable with brake work, it’s always best to consult a professional mechanic. Drive safely!
