Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly (do not remove yet).
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Brake Pads: Remove the caliper assembly by unscrewing the caliper bolts. Check the thickness of the brake pads. Replace if they are below specifications (usually 3mm).
Brake Rotors: Check the rotors for warping using a run-out gauge or by feel. If warped, replace the rotor. If scoring is present, consider resurfacing or replacing.

4. Reassemble Components

Reinstall the brake caliper and ensure it's securely fastened.
Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).

5. Test

Start the vehicle and perform a gentle brake test at low speeds to confirm the issue is resolved.
