Dec 18 2008nbsp018332The cause of this pulsation is because as the rotor rotates into the brake pads and you have the pads applied to the brake rotors that warp or fad spot on the rotor will cause a hydraulic pressure surge it will force the brake pads apart and cause that surge to go backwards thru the system through the master cylinder and into your brake pedal
