"What is that shaking when I am braking?" This vibration from your brakes can be very slight at high braking or just about take the steering wheel out of your hands when coming to a stop. All newer vehicles have front disc brakes and more manufacturers are switching to rear disc brakes instead of drum brakes. If you have ever had a bicycle with the hand brakes, there is a caliper that squeezes the pads on each side of the rim to stop. The disc brakes on your car are similar but the brake pads are squeezed against a metal disc (called a brake rotor) by a hydraulic caliper to stop. What causes that shaking while braking is uneven thickness of the rotor. Sometimes rotors can be resurfaced to make them straight and even. Many newer vehicles are using thinner and lighter rotors, with a different construction. Resurfacing rotors in this case can make them thinner then allowed by the manufacturer and require replacement. Sometimes rotors get thin from normal braking over a long period of time. Continuous hard braking and over tightening the lug nuts can cause rotors to warp. In most cases when replacing the rotors you should include brake pads for the best performance.
