Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues while working.

Tools Required:

Jack and jack stands
Torque wrench
Brake rotor runout gauge
Diagnostic scanner
Socket set

2. Inspect and Replace Brake Rotors

Lift the Vehicle:
- Use the jack to lift the vehicle and secure it with jack stands.
Remove Wheel:
- Using the socket set, remove the lug nuts and take off the wheel.
Inspect Rotors:
- Measure the rotor runout with the gauge. If it exceeds specifications (typically 0.002 inches), the rotor is warped.
Remove Brake Caliper:
- Use the appropriate socket to remove the caliper bolts. Hang the caliper using a wire to avoid stress on the brake line.
Remove Brake Rotor:
- Remove any retaining screws or clips and slide off the rotor.
Install New Rotor:
- Position the new rotor on the hub, ensuring it is seated properly. Reinstall any retaining screws.
Reattach Caliper:
- Reinstall the brake caliper and torque the bolts to manufacturer specifications (usually around 25-30 ft-lbs).

3. Replace Brake Pads (if necessary)

Remove Old Pads:
- Slide out the old brake pads from the caliper bracket.
Install New Pads:
- Lubricate the backing of the new pads with brake grease and install them into the caliper bracket.

4. Reinstall Wheel

Place the wheel back on and hand-tighten the lug nuts. Lower the vehicle and then torque the lug nuts to manufacturer specifications (usually around 100-120 ft-lbs).
