Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the 12V battery for safety.

2. Inspect and Replace Brake Pads

Remove Wheel:
- Use a jack to lift the front of the vehicle and secure it on jack stands.
- Remove the lug nuts with a socket set and take off the wheel.
Inspect Brake Pads:
- Remove the caliper by loosening the caliper bolts.
- Check the thickness of the brake pads; replace if less than 3mm.
Replace Brake Pads:
- If replacement is needed, slide out the old pads and install new ones.
- Ensure the new pads are seated properly in the caliper.

3. Inspect and Replace Rotors

Measure Rotor Runout:
- Reinstall the wheel temporarily and use a dial indicator to measure rotor runout.
- If the runout exceeds manufacturer specifications, the rotor may need resurfacing or replacement.
Remove Rotors:
- Remove the caliper bracket to access the rotor.
- Slide the rotor off the hub.
Install New Rotors:
- If replacement is necessary, install new rotors and secure them properly.
- Reinstall the caliper bracket and caliper.

4. Check Wheel Alignment and Balance

Inspect Tires:
- Check for uneven wear; rotate or replace tires as necessary.
Perform Alignment:
- Use an alignment machine to check and adjust the wheel alignment according to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and lug nuts, ensuring they are torqued to the manufacturer’s specifications.
Lower the vehicle and reconnect the battery.
Test drive the vehicle to verify the issue has been resolved.
