请教：高速刹车方向盘抖动等问题

[cool cat]

虽然开了段时间车却觉得好不了解车。有些问题，请帮我分析一下。谢谢

1. 我的车在高速时候才刹车如果比较力大，方向盘会抖动的挺厉害。在低速下有时候也能感觉出轻微的一颤一颤的力度（车身）。这是啥问题？怎么办好呢？

2.低头看我的排气管上锈迹斑斑，几乎覆盖整个中断（鼓起来的那一块），我该怎么办？

3，冬天的防锈我该做什么样的处理？，我的车是2000年的，用手摸起来地盘上有一层像是硬胶状的物质。看别的一些车下面是喷的一层黑色的图层。两种有什么区别？我该如何处理我的车？冬天除了机油还应该注意些什么？

4. 在低速右转弯的时候，会听见好像从右轮方向传来轻微连续的咯隆咯隆的声音。

1.you may have a deformed rotor.
2.As long as it is not leaking, don't worry about it. You can have a customized stainless steel exhaust line from some place. But does it worth?
3.That is the undercoat. About rust proof, you can go to any place to have it, like rust check..... They spray some tacky oil to those potential rust area and they check it every year. Don't go to dealer, they rip you off.
4.Sounds like the CV-joint is going.

"冬天除了机油还应该注意些什么？"

Finish the preventive maint. before winter comes. Check windshield wipers, tyres, heating system,.....etc. Make sure the windshield liquid tank is always full.

it's not called a deformed rotor it's called a warped rotor
also if your front tire's air pressure is not balanced it could cause BAD vibration during highway braking
