昨天做了次Inspection，发现数个问题，不清楚是不是必须马上修，特来请教诸位高人：
Check brake fliud level and condition and check for leaks: Found brake fliud
to be dirty/contaminated
Check automatic transmission fliud level and condition and check for leaks:
Found automatic transmission fliud leak
Inspect accessory drive belts: Found serpentine belt in poor condition
机械师说第一个最重要，要价175，第二个100.第三个120，不知道合理不。
多谢各位指导。
