2
Check brake pads for uneven wear or damage.
3

Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Allow the vehicle to cool down if it has been driven recently.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly before lifting the vehicle.
Lift the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

a. Inspect Brake Rotors

Use a runout gauge to measure rotor warping. If it exceeds manufacturer specifications (typically 0.004 inches), replace the rotor.
If the rotor is within specs but has significant scoring, consider resurfacing or replacing it.

b. Inspect Brake Pads

Remove the caliper by unscrewing caliper bolts using a socket set.
Check the thickness of brake pads; if they are below 3mm, replace them.
Ensure the pads are not unevenly worn; replace if necessary.

c. Reassemble Components

If rotors and pads are replaced, install new pads and reattach the caliper securely.
Replace the wheel, hand-tighten the lug nuts, and lower the vehicle.
Torque the lug nuts to the manufacturer's specification (usually around 80-100 ft-lbs).
