Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the engine is off and the keys are removed from the ignition.

2. Remove Wheel

Loosen the lug nuts on the affected wheel using a socket set.
Elevate 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 Rotors

Inspection:
- Check the rotor's surface for warping or scoring using a dial indicator.
- If warped beyond manufacturer's specifications (typically 0.001 inches), proceed to replace.
Replacement:
- Remove the caliper by unbolting it from the bracket and suspend it using a bungee cord.
- Remove the caliper bracket bolts and take off the bracket.
- Remove the old rotor by sliding it off the hub.
- Install the new rotor, ensuring it is seated properly.
- Reinstall the caliper bracket and torque to manufacturer specifications (typically 80-100 ft-lbs).
- Reattach the caliper and torque its bolts to manufacturer specifications (typically 25-35 ft-lbs).

4. Inspect and Replace Brake Pads

Check the brake pads for thickness; replace if they are below 3mm.
Remove the old brake pads from the caliper bracket.
Apply brake grease to the backing of the new pads to prevent squealing.
Install the new pads into the caliper bracket.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts to the manufacturer's torque specifications (typically 80-100 ft-lbs).
Test the brakes by pressing the pedal gently to seat the pads against the new rotors.
