Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety.

2. Raise the Vehicle

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

3. Inspect and Replace Brake Rotors

Inspection:
- Measure rotor thickness with a micrometer; replace if below specifications.
- Check for warping using a runout gauge; replace if warped.
Replacement:
- Remove the brake caliper bolts and slide the caliper off the rotor.
- Remove the old rotor by unscrewing any retaining screws and pulling it off the hub.
- Install the new rotor, ensuring it is seated properly on the hub.
- Reinstall the brake caliper and tighten bolts to manufacturer specifications.

4. Inspect and Replace Brake Pads

Remove the caliper bracket if necessary.
Take out the old brake pads, inspecting for uneven wear.
Install new brake pads, ensuring they are properly aligned in the caliper brackets.
Apply brake grease to the back of the pads to prevent squealing.

5. Reassemble and Lower the Vehicle

Reattach the caliper and tighten all bolts to the specified torque.
Reinstall the front wheels and lower the vehicle.
Reconnect the battery.
