Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Inspect and Replace Brake Rotors

Tools Required: Jack and jack stands, lug wrench, torque wrench, dial indicator.
Raise the vehicle using a jack and secure with jack stands.
Remove the front wheels using a lug wrench.
Use a dial indicator to check for rotor runout; replace if warped (more than 0.002 inches).
Remove caliper mounting bolts and slide the caliper off the rotor.
Remove the rotor and replace it with a new one, ensuring it is clean and free of rust.

3. Inspect and Replace Brake Pads

Check the thickness of the brake pads; replace if less than 3mm.
If replacing, remove the caliper bracket and old pads.
Install new pads, ensuring they are properly aligned.
Reattach the caliper and torque the bolts to manufacturer specifications.

4. Wheel Alignment Check

After replacing rotors and pads, perform a wheel alignment.
Adjust camber, caster, and toe as needed to ensure proper alignment.
Confirm alignment settings meet manufacturer specifications.

5. Test Drive and Final Inspection

Reinstall the wheels and torque the lug nuts to the specified torque.
Lower the vehicle and take it for a test drive to verify the issue is resolved.
Check for any unusual noises or vibrations during braking.
