Solution

1. Preparation

Tools Required: Lift or jack stands, wheel chocks, lug wrench, torque wrench, brake cleaner, and safety glasses.
Ensure the vehicle is parked on a level surface. Engage the parking brake and place wheel chocks behind the rear wheels.

2. Remove Wheel

Loosen the lug nuts on the front or rear wheel (depending on where the issue is suspected).
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 bolts using a socket and ratchet.
Gently lift the caliper and secure it with a bungee cord to avoid strain on the brake line.
Inspect brake pads for uneven wear; replace if worn down to the wear indicator.

Brake Rotors

Check the rotor surface for warping by using a dial indicator or visually inspecting for grooves and discoloration.
If warped, replace the rotor with a new one and ensure proper specifications.

4. Reassemble Components

Reattach the caliper and torque the caliper bolts to the manufacturer's specifications (usually around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Torque Lug Nuts

Carefully lower the vehicle and remove the jack stands.
Torque the lug nuts to the recommended specifications (typically between 80-100 ft-lbs).
