Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect the brake pads for uneven wear; replace if necessary.
  - Tools Required: Socket set, brake caliper tool.
3. Ensure the new brake pads are properly seated in the caliper.

3. Check and Resurface or Replace Rotors

Sub-steps:
1. Remove the caliper and rotor from the hub.
2. Inspect the rotor for warping or scoring; measure with a micrometer.
3. If warped, either resurface the rotor or replace it with a new one.
  - Tools Required: Brake rotor gauge, impact wrench for removal.
4. Clean the rotor surface before reinstallation.

4. Reassemble and Torque Components
