1. Safety First:
- Engage the parking brake and chock the wheels that will remain on the ground to prevent the vehicle from rolling.
- Use proper safety gear, such as safety glasses and gloves.
2. Tools Needed:
- Jack
- Jack stands or ramps
- Socket set
- Wrench
- New rotors
- Brake caliper lubricant
- Brake cleaner
- Wire brush
3. Prepare the Vehicle:
- Loosen the lug nuts of the wheel you'll be working on by turning them counterclockwise, but don't remove them completely yet.
- Lift the vehicle using the jack and place the jack stands or ramps securely to support the vehicle safely.
4. Remove the Wheel:
- Remove the lug nuts and gently take the wheel off the vehicle.
5. Remove the Caliper:
- Locate the brake caliper, usually attached to the rotor with two bolts.
- Remove the bolts holding the caliper in place and carefully lift it off the rotor.
- Note the position of the caliper bolts and shims (thin metal plates) for reinstallation.
6. Remove the Old Rotor:
- Check for any rust buildup or corrosion on the rotor's contact surfaces.
- Remove the rotor by sliding it off the wheel hub.
7. Clean and Inspect the Hub:
- Use the wire brush to clean any leftover residue from the rotor hub surface.
- Inspect for any damage or uneven wear on the hub.
8. Install the New Rotor:
- Slide the new rotor onto the wheel hub. Make sure it's sitting flush and centered.
9. Reinstall the Caliper:
- Reinstall the caliper bolts along with the shims that you noted earlier.
- Tighten the caliper bolts securely but do not overtighten them.
10. Reinstall the Wheel:
- Carefully put the wheel back onto the vehicle and screw on the lug nuts by hand.
- Do not tighten the lug nuts completely at this point.
11. Lower the Vehicle:
- Slowly lower the vehicle off the jack stands or ramps.
12. Tighten the Lug Nuts:
- Use a wrench to tighten the lug nuts in a star pattern until they are snug but not overtightened.
13. Test Drive and Brake Bedding:
- Perform a test drive and pay attention to any unusual sounds or vibrations.
- Perform brake bedding to ensure proper seating of brake pads and rotors. This involves a process of controlled stops and gradual increases in braking force. Consult the vehicle's manual or a qualified mechanic for specific instructions on brake bedding for your vehicle.
14. Check Brake Fluid Level:
- Make sure the brake fluid reservoir is at the appropriate level.
Remember that replacing rotors can be a complex task, so if you're not comfortable working on your vehicle, it's advisable to seek help from a qualified mechanic.
