Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Raise the Vehicle

Use a jack to lift the front of the vehicle and secure with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Rotors

Remove the caliper by unbolting it from the bracket using the appropriate socket.
- Tools Required: Socket set, torque wrench
Hang the caliper using a wire to avoid straining the brake line.
Remove the brake pads from the caliper bracket.
Measure the rotor thickness using a micrometer; replace if below specification or if warped.
To replace, unbolt the rotor from the hub and install the new rotor, securing it to the hub.
Torque rotor bolts to manufacturer specifications.

4. Replace Brake Pads

Install new brake pads into the caliper bracket.
Reattach the caliper over the new pads and torque the caliper bolts to specification.

5. Reassemble and Lower Vehicle

Reinstall the front wheels and torque lug nuts to specifications.
Remove jack stands and lower the vehicle.

6. Test Brakes

Pump the brake pedal to ensure proper pad seating.
Perform a test drive to check for vibrations during braking.
