Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during work.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the wheel using a lug wrench.
2. Unscrew the brake caliper mounting bolts and remove the caliper.
3. Remove the brake rotor from the hub.
4. Measure the rotor thickness using a micrometer; replace if below specification.
