When the brakes are working normally, if the coefficient of friction between the rubbing surfaces in the brakes tends to decrease as the velocity increases, negative damping may result, producing the vibration known as 'brake judder' or 'brake chatter', at low frequencies, or ' brake squeal ' at high frequencies. Brake Discs and Pads. Caution: Immediately after installing new pads, rotors or a big brake kit, the first few applications of the brakes will result in very little braking power.
