Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, lug nut wrench, torque wrench, dial indicator, OBD-II scanner.
Safety Warnings: Ensure the vehicle is on a level surface and the engine is off. Use wheel chocks to prevent rolling.

2. Lift the Vehicle

Loosen the lug nuts on the front wheels slightly while the vehicle is still on the ground.
Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels.

3. Inspect Brake Components

Brake Pad and Rotor Inspection:
- Remove the caliper by unscrewing the caliper bolts.
- Slide the caliper off and secure it without straining the brake line.
- Inspect the brake pads for uneven wear and replace if necessary.
- Check the rotors for warping or scoring. Measure rotor thickness and runout; replace if beyond specifications.
- If rotors are warped, consider resurfacing or replacing them.

4. Check Wheel Alignment and Balance

Inspect the front tires for uneven wear patterns which may indicate alignment issues.
Have the alignment checked and corrected if necessary.
Balance the tires if uneven wear is found.

5. Reassemble and Torque

Reinstall the brake caliper and secure the caliper bolts to the manufacturer’s specifications (typically around 25-30 Nm).
Reattach the front wheels and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually between 100-120 Nm).

6. Test Drive

Perform a test drive to ensure the issue is resolved. Monitor for any vibrations during braking.
