Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Use wheel chocks to prevent vehicle movement.

2. Raise the Vehicle

Sub-steps:
1. Loosen the lug nuts on the front wheels slightly while the vehicle is on the ground.
2. Use a jack to lift the front of the vehicle and secure it with jack stands.
3. Remove the front wheels completely.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the brake caliper by taking out the caliper bolts using a socket set.
2. Slide the caliper off the rotor and hang it using a bungee cord (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket; note their orientation for installation of new pads.
4. Inspect the calipers and replace if necessary.
5. Install new brake pads, ensuring they are positioned in the same orientation as the old ones.
6. Reinstall the brake caliper over the new pads and torque the caliper bolts to manufacturer specifications (typically around 20-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If rotors are scored or warped, remove the rotor from the hub by removing the retaining screws (if applicable).
2. Clean the hub surface with a wire brush to ensure proper seating of the new rotor.
3. Install the new rotor, securing it with the retaining screws.
4. Repeat the process for the opposite side if needed.

5. Reassemble and Lower the Vehicle

Sub-steps:
1. Reinstall the front wheels and hand-tighten the lug nuts.
2. Lower the vehicle back to the ground and fully tighten the lug nuts in a star pattern to the manufacturer’s torque specifications (typically around 80-100 ft-lbs).
3. Recheck brake fluid level and top off if necessary.
