Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, OBD-II scanner, brake cleaner, and safety glasses.
Instructions:
- Park the vehicle on a flat surface and engage the parking brake.
- Disconnect the battery to ensure safety during the repair.

2. Inspect and Replace Brake Rotors

Instructions:
1. Loosen the lug nuts on the front wheels.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the front wheels using a lug wrench.
4. Inspect the brake rotors for signs of warping or uneven wear (look for grooves or discoloration).
5. If rotors are warped, replace them with new OEM-spec rotors.
6. Clean the hub surface with brake cleaner before installing new rotors.

3. Inspect and Replace Brake Pads

Instructions:
1. Remove the caliper bolts using the appropriate socket.
2. Carefully lift the caliper away from the rotor and support it (do not let it hang by the brake line).
3. Inspect the brake pads for thickness; replace if worn below 3mm.
4. Install new pads, ensuring they are properly positioned and seated.
5. Reinstall the caliper and torque the caliper bolts to the manufacturer’s specifications (typically around 25-35 ft-lbs).

4. Check Suspension and Wheel Alignment

Instructions:
1. Inspect the control arms, tie rods, and ball joints for wear or damage.
2. Replace any worn suspension components as needed.
3. After repairs, take the vehicle to a professional alignment shop to ensure proper wheel alignment.

5. Reinstall Wheels and Finalize

Instructions:
1. Reinstall the front wheels and hand-tighten the lug nuts.
2. Lower the vehicle off the jack stands and torque the lug nuts to the manufacturer’s specifications (typically around 100-110 ft-lbs).
3. Reconnect the battery.
