Solution

1. Preparation

Tools Required: Socket set, jack stands, wheel chocks, lug wrench
Sub-steps:
1. Park the vehicle on a level surface and engage the parking brake.
2. Place wheel chocks behind the rear wheels for safety.
3. Loosen the lug nuts on the front wheels slightly but do not remove them.

2. Raise the Vehicle

Sub-steps:
1. Use a hydraulic jack to lift the front of the vehicle.
2. Secure the vehicle with jack stands for safety.
3. Remove the front wheels completely.

3. Inspect Brake Components

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the brake rotor and suspend it using a bungee cord (do not let it hang by the brake line).
3. Check the brake pads for thickness; replace if they are less than 3mm.
4. Inspect the brake rotor for grooves or damage; measure thickness and replace if below the manufacturer's specifications.

4. Replace Brake Pads and Rotors (if necessary)

Sub-steps:
1. If replacing pads, remove the old pads from the caliper bracket.
2. Apply brake grease to the back of the new pads and install them into the caliper bracket.
3. If replacing rotors, remove the old rotor and install the new rotor, ensuring it’s properly seated.
4. Reinstall the caliper over the new pads and rotor, and torque the caliper bolts to the manufacturer's specifications (typically around 20-30 ft-lbs).

5. Reassemble Vehicle

Sub-steps:
1. Reinstall the front wheels and hand-tighten the lug nuts.
2. Lower the vehicle back to the ground using the hydraulic jack.
3. Torque the lug nuts to the manufacturer's specifications (typically around 76 ft-lbs).

6. Final Inspection

Sub-steps:
1. Pump the brake pedal several times to seat the pads against the rotor.
2. Check and top off brake fluid if necessary.
3. Perform a final check for any visible leaks or loose components.
