How Do Car Brakes Cause Vibrations?
Modern automobiles use disc brakes, which consist of a caliper and a rotor assembly. A caliper acts very much like a hand in the way that it grips the rotor, which causes the braking action. The caliper is attached to a bracket that holds it securely on top of the rotor. The rotor is a flat circular disc mounted over the wheel studs. This disc spins with the wheel, while the caliper is held immobile with the rotor passing through it. The caliper has two brake pads mounted on it that come in contact with the rotor. When the brakes are applied, the caliper acts like a hand and squeezes the rotor, using the resulting friction to slow the rotation of the rotor and the car. Vibration Causes The rotors are the major culprit for causing vibrations felt in the car and in the brake pedal. Rotors are very precise in that they cannot be out of round even two-thousandths of an inch or they will cause a vibration. When they are out of round, they tend to wobble as they are rotated. As they pass thr
