Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, and OBD-II scanner.
Parts Required: New brake pads, new rotors (if warped), wheel weights (if needed for balancing).
Safety Warnings: Ensure the vehicle is on a flat surface and securely lifted before working underneath.

2. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors:
- Remove the wheel using the lug wrench.
- Inspect the brake pads for thickness; replace if worn below 3mm.
- Check rotors for warping using a dial indicator; replace if warped beyond manufacturer specs.
Replace Brake Pads and Rotors:
- Clean the caliper and rotor surface with brake cleaner.
- Install new rotors and brake pads, ensuring all hardware is tightened to manufacturer specifications.
- Torque Values: Refer to vehicle service manual for specific torque settings for caliper bolts.

3. Check and Adjust Wheel Alignment

Inspect Tire Condition:
- Check for uneven wear patterns on the tires.
- Replace any damaged or excessively worn tires.
Align Wheels:
- Take the vehicle to a professional alignment shop to ensure proper wheel alignment.
