Solution

1. Preparation

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

2. Wheel Removal

Loosen the lug nuts on the front wheels slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheels completely.

3. Brake Inspection

Rotors:
- Use a dial indicator to check for rotor warpage. It should not exceed manufacturer specifications (typically within 0.002 inches).
- If warped, proceed to replace the rotors.
Pads:
- Measure the thickness of the brake pads; replace if below manufacturer specifications (usually less than 1/8 inch).
- Check for any uneven wear patterns.

4. Rotor Replacement (if necessary)

Remove the caliper by unbolting it from the bracket and suspend it using a wire to avoid straining the brake line.
Remove the bracket bolts and take off the old rotor.
Install the new rotor and torque the bolts to the specified value (usually around 85-100 lb-ft).
Reattach the caliper and torque its bolts to the specified value (typically around 25-30 lb-ft).

5. Brake Pad Replacement (if necessary)

Remove old pads from the caliper bracket.
Apply brake lubricant to the backing of the new pads to prevent noise.
Install new pads in the bracket and ensure they fit snugly.

6. Reassembly

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications (usually around 100-120 lb-ft).
Repeat on the other side if applicable.
