Safety gear: gloves and safety glasses.

2. Wheel Removal

Sub-steps:
1. Loosen the lug nuts using a lug wrench.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.
Tools Required: Lug wrench, jack, jack stands.

3. Brake Inspection

Sub-steps:
1. Inspect the brake pads for uneven wear or cracking.
2. Remove the brake caliper by loosening the caliper bolts; hang it securely to avoid stress on the brake line.
3. Check the rotors for warping using a dial indicator; replace if runout exceeds manufacturer specifications.
Tools Required: Socket set, dial indicator.

4. Brake Rotor Replacement (if necessary)

Sub-steps:
1. Remove the old rotor by unscrewing any retaining screws and pulling it off the hub.
2. Clean the hub surface with brake cleaner to ensure a good seating for the new rotor.
