Q: Brakes shake the car, what makes that happen?

I can understand the frustration with this problem and to assist with fixing the concern, it is best to understand why we see the issue re-occurring. Disc brake rotors that have been resurfaced are more susceptible to being overheated. When you put pressure on the brake pedal and begin to apply the brakes, the surface of the brake pad mates with the surface of the brake rotor to slow down the vehicle. When this happens, heat is generated and some of the material from the brake pad is transferred to the rotor. Areas of the resurfaced rotor can become more heated than other areas, called hotspots, and cause more material from the brake pad to adhere to the rotor. This creates an uneven surface for the brake pad to grab the rotor and in turn transmits a pulsation to the steering wheel. The solution to your vehicle’s problem is pretty straight forward, have a certified technician更换前盘式制动转子和盘式刹车片。除了更换这些零件外，还必须正确进行维修，例如从符合盘式制动器转子的轮毂表面上除去任何锈蚀和碎屑。这里的任何锈蚀和碎屑都可以防止两个表面均匀地交配，并在制动时向方向盘传输振动。适当的润滑卡钳滑动螺栓将使卡尺根据需要自由移动而无需结合，这可能会导致不必要的振动。使用扭矩扳手将每个凸耳螺母拧紧到工厂规格，并以适当的拧紧序列将转子均匀固定在轮毂和车轮之间。在扭矩的凸耳上可以使转子的位置变形，而转子的位置又可以传递振动。
