Solution

1. Preparation

• Gather all necessary tools and parts.
• Park the vehicle on a flat surface and engage the parking brake.
• Wear safety glasses and gloves.

2. Raise the Vehicle

• Use a jack to lift the front or rear of the vehicle, depending on where the brakes are being serviced.
• Secure with jack stands for safety.

3. Inspect and Replace Brake Components

A. Brake Rotor Removal

• Remove the wheel using a socket set.
• Unbolt the caliper bracket and hang it securely (do not let it hang by the brake line).
• Remove the rotor; if stuck, use a rubber mallet to gently tap it off.

B. Brake Pad Inspection and Replacement

• Check brake pads; if worn below the manufacturer's specification, replace them.
• Remove old pads and install new ones, ensuring they are seated correctly.

C. Brake Rotor Replacement

• If rotors are warped, replace them with new rotors.
• Clean the new rotors with brake cleaner to remove any protective oil.
• Install new rotors onto the hub.

4. Reassemble and Torque

• Reinstall the caliper bracket and torque to manufacturer specifications.
• Reattach the wheel and torque lug nuts in a crisscross pattern to the specified torque value.

5. Lower the Vehicle

• Remove jack stands and carefully lower the vehicle.
• Perform a final check to ensure all components are secured.
