Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Inspect and Replace Brake Pads

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner.
Remove the wheel using the lug wrench.
Inspect brake pads for wear; replace if they are below the manufacturer's specifications.
Use brake cleaner to clean the caliper and rotor surfaces.

3. Check and Resurface/Replace Brake Rotors

Tools Required: Torque wrench, brake rotor tool (if needed).
Measure rotor thickness; if below minimum specification or warped, remove the rotors.
Resurface or replace the rotors as required.
Reinstall rotors and torque to manufacturer specifications.

4. Inspect Wheel Bearings

Tools Required: Socket set, torque wrench.
Remove the brake caliper and rotor.
Check for play in the wheel bearings by shaking the rotor.
Replace bearings if any play is detected or if they are damaged.

5. Align and Balance Tires

Tools Required: Alignment rack (usually requires professional service).
Check tire balance; re-balance if necessary.
Ensure that the alignment is within manufacturer specifications and adjust as needed.
