Inspect Brake Pads and Rotors: Look for excessive wear or discoloration; replace if necessary.
- Tools Required: Torque wrench for reinstallation.
- Replacement Parts: New brake pads and rotors if worn.
Clean Brake Components: Use brake cleaner to remove dust and debris from pads and rotors before reassembly.

3. Oil and Fluid Check

Check Engine Oil: Remove the dipstick; if oil smells burnt, it needs changing.
- Replacement Parts: New engine oil and filter.
Replace Oil: Drain old oil, replace filter, and refill with new oil (consult owner's manual for specifications).
Check Transmission Fluid: If burnt, drain and replace with the appropriate fluid.

4. Electrical Inspection
