Solution
1. Preparation
  • Gather Tools and Parts: Ensure you have the following tools and parts ready:
    • OBD-II scanner
    • Socket set
    • Torque wrench
    • Brake cleaner
    • Replacement brake pads (if needed)
  • Safety Precautions: Disconnect the battery before working on electrical systems. Allow the engine to cool before inspecting components.
2. Inspect and Repair Brake Components

  • Step 1: Remove the wheel

    • Loosen lug nuts with a socket set.
    • Lift the vehicle using a jack and secure it with jack stands.
    • Remove the lug nuts and take off the wheel.

  • Step 2: Inspect brake pads and rotors

    • Check the thickness of the brake pads; replace if worn down to less than 3mm.
    • Inspect the rotors for scoring or warping.

  • Step 3: Replace brake pads (if necessary)

    • Remove the caliper bolts using a socket set.
    • Slide the caliper off and support it without straining the brake line.
    • Replace the old pads with new ones, ensuring proper orientation.
    • Reinstall the caliper and torque the bolts to manufacturer specifications.
3. Examine Belts and Hoses

  • Step 1: Check the serpentine belt for wear

    • Look for cracks or fraying; replace if damaged.

  • Step 2: Inspect hoses for leaks

    • Feel along hoses for signs of coolant leaks or deterioration; replace as necessary.
4. Check Engine Oil

  • Step 1: Check oil level

    • Remove the dipstick, wipe it clean, reinsert, and check the level. Add oil if low.

  • Step 2: Change oil if burnt

    • If the oil appears dark or has a burnt smell, drain it using an oil pan, replace the oil filter, and refill with the appropriate oil type.
