Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Sub-steps:
- Park the vehicle on a flat surface and engage the parking brake.
- Gather all necessary tools and safety equipment.
- Allow the vehicle to cool if it has been driven recently.

2. Lift the Vehicle

Sub-steps:
- Loosen the lug nuts on the front wheels slightly without removing them.
- Use the jack to lift the front of the vehicle and secure it with jack stands.
- Remove the lug nuts and take off the front wheels.

3. Inspect Brake Components

Sub-steps:
- Remove the brake caliper by loosening the caliper bolts with a socket set.
- Carefully slide the caliper off the rotor and suspend it with a bungee cord to avoid stress on the brake line.
- Inspect the brake pads for thickness; if they are below 3mm, they should be replaced.
- Check the brake rotor for grooves, scoring, or warping. Measure the rotor thickness with calipers to ensure it meets specifications.

4. Replace or Resurface Components

Sub-steps:
- If brake pads are worn, remove them from the caliper bracket and replace with new pads.
- If the rotor is damaged, either replace it or have it resurfaced if it’s within allowable thickness limits.
- Reinstall the caliper over the new pads or resurfaced rotor and tighten caliper bolts to the manufacturer's torque specifications.

5. Reassemble and Test

Sub-steps:
- Reinstall the wheel, tightening the lug nuts by hand.
- Lower the vehicle to the ground and then fully tighten the lug nuts in a crisscross pattern using a torque wrench.
- Pump the brake pedal a few times to ensure proper pad seating and brake operation.
