Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear appropriate safety gear (gloves and goggles).

2. Lift the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure it with jack stands for safety.

3. Remove Wheel

Use a socket set to remove lug nuts.
Carefully take off the wheel to access the brake components.

4. Inspect and Replace Brake Rotors (if necessary)

Inspection:
- Check rotors for warping using a dial indicator.
- Measure rotor thickness with a micrometer.
Replacement (if warped):
- Remove caliper bolts using a torque wrench.
- Slide the caliper off the rotor and secure it (do not hang by the brake line).
- Remove the rotor mounting screws and pull the rotor off.
- Install the new rotor, ensuring it is properly seated.
- Reattach caliper and torque bolts to manufacturer specifications.

5. Inspect and Replace Brake Pads (if necessary)

Inspection:
- Check pad thickness and look for uneven wear.
Replacement (if worn):
- Remove the caliper bracket if necessary.
- Slide the old pads out and replace with new pads.
- Use brake grease on the backing of the new pads to prevent squeaking.

6. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten lug nuts.
Lower the vehicle and then torque the lug nuts to manufacturer specifications.
