车子冷车发动会有尖叫声是怎么回事？

好像是轮子、刹车那边发出的，几秒种后就没事了，各位有类似的经验么？是甚么问题？

pad该换了？

If your car is not moving, check all the belts driven by your engine.

好的

这就去瞅瞅

能看到的似乎都很新，连上面的字都还没磨掉那

my labmate's car has the same problem.
According to him, it's a problem with the airconditioning system.
He's been driving his car like this for at least 2 months now
But....I recommend you have it checked out....it's better to be safe than sorry

This is called the morning symptom a.k.a. as v-belt noise. Low temp. causes rubber to harden thus less traction/ friction. It usually will go away after the engine warms up. If a squealing noise comes out everytime you turn the steering wheel, then it is the power steering pump belt. Likewise, it comes out when a/c is on, then a/c compressor belt. If you don't want to get your hands dirty, go to Walmart buy a spray bottle of belt dressing then spray on the belt contact surface. However I am not a big fan of this quick and not-so-dirty solution. I highly recommend buying a set of simple hand tools to tighten the belt(s), and do all kinds of maintainace work around your car. Get your hand dirty!
