Solution

1. Preparation

Tools Required: Socket set, wrench set, OBD-II scanner, brake cleaner, safety goggles, gloves, jack and jack stands.
Ensure the vehicle is parked on a level surface, and the engine is cool before starting work.

2. Inspect and Replace Brake Components

Raise the Vehicle: Use the jack to lift the front or rear of the vehicle as needed, and secure with jack stands.
Remove Wheel: Use a socket set to remove the lug nuts and take off the wheel.
Inspect Brake Pads and Rotors:
- Check for wear indicators on the brake pads.
- Look for scoring or excessive wear on the rotors.
Replace Brake Pads (if necessary):
- Remove the caliper bolts and slide the caliper off.
- Remove old brake pads and install new ones.
- Reinstall the caliper and torque bolts to manufacturer specifications (usually around 25-30 lb-ft).
Reinstall Wheel: Put the wheel back on and hand-tighten the lug nuts.

3. Address Engine Oil or Fluid Leaks

Inspect for Leaks: Look for any signs of oil or fluid leaks around the engine and under the vehicle.
Replace Worn Seals or Gaskets: If leaks are found, replace affected seals or gaskets.
Top Off Fluids: Ensure all necessary fluids (engine oil, coolant) are at proper levels.
