Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, wire brush, anti-seize lubricant.
Park the vehicle on a flat surface, engage the parking brake, and turn off the ignition.
Disconnect the battery if applicable.

2. Raise the Vehicle

Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel using a lug wrench.

3. Inspect and Clean Brake Components

Remove the brake caliper by loosening the caliper bolts with a socket set.
Carefully slide the caliper off the rotor without stretching the brake line.
Inspect the brake pads for wear; replace if thickness is less than 3mm.
Clean the rotor surface with brake cleaner and a wire brush to remove any debris or rust.
Ensure the rotor is smooth; if scored, consider resurfacing or replacing.

4. Replace or Reinstall Brake Pads

If pads are worn, remove the old pads and install new pads.
Apply anti-seize lubricant to the backing of the new brake pads.
Reattach the caliper over the new pads, ensuring a proper fit.
Torque the caliper bolts to the manufacturer's specifications (typically around 25-35 ft-lbs).

5. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and fully tighten the lug nuts to the specified torque (usually about 80-90 ft-lbs).
