Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Remove Wheel

Tools Required: Socket set, lug wrench
Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle with a jack and secure it on jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Brake Pads

Remove the caliper bolts using a socket set.
Slide the caliper off the rotor and support it with a bungee cord (do not hang by the brake line).
Inspect the brake pads; replace if they are worn unevenly or below the manufacturer's thickness specification.
Tools Required: Torque wrench, bungee cord

Brake Rotors

Check the rotor for warping using a dial indicator. If warped beyond acceptable limits (usually 0.002 inches), replace the rotor.
If the rotor is within specifications, it can be resurfaced if needed.
Tools Required: Brake rotor gauge, impact wrench (if bolts are seized)

4. Reassemble and Torque

Reinstall the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's specified torque (usually around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Torque Lug Nuts

Lower the vehicle off the jack stands.
Torque the lug nuts to the manufacturer's specification (typically 76-83 ft-lbs).
Tools Required: Torque wrench
