1. Gather the Necessary Tools and Materials:
- Lug wrench
- Socket wrench
- Breaker bar (if needed)
- Jack and jack stands
- C-clamp or caliper spreader (optional)
- New front rotors
- Brake pads (if necessary)
2. Prepare the Vehicle:
- Engage the parking brake.
- Ensure the transmission is in Park (for an automatic) or in first gear (for a manual).
- Chock the rear wheels.
- Jack up the front end and secure the vehicle on jack stands for safe access to the wheels and rotors.
3. Remove the Wheel:
- Use the lug wrench to loosen and remove the lug nuts on the affected wheel.
- Pull the wheel straight toward you to remove it.
4. Remove the Brake Caliper:
- Locate the brake caliper.
- Use a socket wrench to remove the bolts or pins holding the caliper in place.
- Gently pry the caliper off the rotor; you may need to use a C-clamp or caliper spreader in case the caliper is stuck.
5. Remove the Old Rotor:
- Locate the rotor.
- Look for small bolts or pins holding the rotor to the hub assembly; remove them if present.
- If there are no retaining bolts, the rotor should come off freely by pulling or wiggling it.
6. Inspect and Clean the Rotor Hub:
- Inspect the rotor hub for rust or build-up and clean it as needed.
7. Install the New Rotor:
- Place the new rotor on the hub assembly, ensuring proper alignment.
- If the rotor has retainer bolts or pins, insert and secure them now.
- Make sure the rotor is flat against the hub and fully seated.
8. Reinstall the Brake Caliper:
- Place the brake caliper back onto the rotor.
- Reinsert the bolts or pins you removed earlier and tighten them securely.
9. Remount the Wheel:
- Place the wheel back on the hub.
- Reinstall the lug nuts; hand-tighten them first, then use the lug wrench to tighten them further in a star pattern.
- Lower the vehicle from the jack stands.
10. Test the Brakes:
- Before driving, test the brakes by pressing the brake pedal several times. Ensure that the pedal feels firm and there are no signs of any issues.
Remember, safety is crucial when working on brakes. If you're uncomfortable with any of these steps or unsure of yourself, it's advisable to seek assistance from a qualified mechanic or refer to a vehicle repair manual for your specific model.
