Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Inspect and Remove Front Wheels

Sub-steps:
- Loosen lug nuts on the front wheels using a lug wrench.
- Raise the vehicle using a jack and secure it with jack stands.
- Remove the front wheels to access the brake components.

Tools Required: Lug wrench, jack, jack stands

3. Inspect Brake Components

Sub-steps:
- Visually inspect brake pads for thickness; replace if less than 3mm.
- Check rotors for warping or grooves; measure rotor thickness with a micrometer.
- If warping is detected (usually more than 0.002 inches), consider resurfacing or replacing rotors.

Tools Required: Micrometer, brake pad thickness gauge

4. Replace or Resurface Brake Rotors

Sub-steps:
- If replacing, remove the caliper brackets using a socket set and hang them with a wire to avoid strain on the brake lines.
- Remove the old rotors and install new or resurfaced rotors in reverse order.
- Torque caliper bracket bolts to manufacturer's specifications (typically around 85 lb-ft).

Tools Required: Socket set, torque wrench

5. Install New Brake Pads

Sub-steps:
- Apply brake grease to the back of the new pads to prevent squeaking.
- Install new pads by sliding them into place and ensuring they are seated correctly.

Tools Required: Brake grease, socket set

6. Reassemble and Test

Sub-steps:
- Reinstall the wheels and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually 76 lb-ft).
- Pump the brakes a few times to ensure proper pad seating before driving.

Tools Required: Torque wrench
