Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors (if needed)

Inspection: Measure the rotor thickness with a micrometer; compare with manufacturer specifications.
Replacement:
1. Remove the caliper by unscrewing the caliper bolts.
2. Hang the caliper using a bungee cord to avoid straining the brake line.
3. Remove the old rotor by unscrewing any retaining screws and sliding it off the hub.
4. Install the new rotor, ensuring it is positioned correctly.
5. Reattach the caliper over the new rotor and torque the caliper bolts to manufacturer specifications.

4. Inspect and Replace Brake Pads (if needed)

Check the thickness of the brake pads; replace if below manufacturer specifications.
Replacement:
1. Remove the caliper bracket if necessary.
2. Slide the old pads out of the bracket.
3. Install new pads in the same orientation as the old ones.
4. Reassemble the caliper and bracket, ensuring all bolts are torqued to specifications.

5. Reinstall Wheel and Test

Reinstall the wheel and torque the lug nuts to manufacturer specifications in a star pattern.
Lower the vehicle and reconnect the battery.
Test drive the vehicle to ensure the issue is resolved.
