Solution

1. Preparation

Gather tools: socket set, torque wrench, jack and jack stands, brake cleaner, and safety glasses.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Replace Brake Pads (if applicable)

Sub-steps:
1. Loosen the lug nuts on the front wheels and raise the vehicle with a jack.
2. Secure the vehicle with jack stands and remove the front wheels.
3. Remove the caliper bolts using a socket wrench and carefully slide the caliper off.
4. Remove the old brake pads and inspect the rotor for damage.
5. Clean the rotor with brake cleaner and install new brake pads.
6. Reattach the caliper, ensuring bolts are torqued to manufacturer specifications (typically around 25-30 ft-lbs).
7. Reinstall the wheels, lower the vehicle, and tighten lug nuts to 76 ft-lbs.

3. Inspect and Replace Serpentine Belt (if applicable)

Sub-steps:
1. Locate the serpentine belt routing diagram under the hood for reference.
2. Use a socket or wrench to release tension on the tensioner pulley.
3. Remove the old belt and inspect pulleys for wear or damage.
4. Install the new serpentine belt, following the routing diagram.
5. Release tension and ensure belt is seated properly on all pulleys.
