Solution

1. Preparation

Gather Tools: Obtain a jack, jack stands, lug wrench, torque wrench, dial indicator, and OBD-II scanner.
Safety Precautions: Ensure the vehicle is on a flat surface, engage the parking brake, and wear safety glasses.

2. Remove Wheels

Loosen lug nuts with a lug wrench while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheels.

3. Inspect and Replace Brake Rotors (if warped)

Rotor Measurement: Use a dial indicator to check for rotor runout. If the runout exceeds manufacturer specifications, replace the rotors.
Remove Brake Calipers: Unbolt the caliper bracket and carefully hang it to avoid straining brake lines.
Remove Rotors: Take off the rotors by removing any retaining screws or clips.
Install New Rotors: Place new rotors onto the hub, ensuring they are seated properly.

4. Replace Brake Pads

Remove old brake pads from the caliper bracket.
Lubricate the backing of new pads with brake grease to prevent squeaking.
Install new brake pads into the caliper bracket.

5. Reassemble Braking System

Reattach the brake calipers over the new pads and rotors.
Torque the caliper bolts to the manufacturer's specifications.
Reinstall the wheels and torque lug nuts to the specified value.

6. Final Checks

Lower the vehicle and perform a visual inspection to ensure everything is properly assembled.
Pump the brake pedal a few times to seat the brake pads against the rotors.
