Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect Brake Components

Brake Pads: Remove the caliper by unbolting it and check for uneven wear; replace if necessary.
Brake Rotors: Measure rotor thickness and check for warping with a run-out gauge. If warped, replace the rotors.
Calipers: Inspect for any sticking or binding; clean and lubricate sliders if needed.

4. Reassemble Components

If any brake parts were replaced, reinstall the new pads and rotors.
Reattach the caliper and tighten bolts to manufacturer specifications (typically 25-35 lb-ft).
Put the wheel back on and hand-tighten the lug nuts.

5. Lower Vehicle and Test

Remove jack stands and lower the vehicle.
Torque the lug nuts to the specified value (usually 75-90 lb-ft).
Reconnect the battery.
