APPARATUS AND METHOD OF AUTOMOTIVE BRAKE WITH BOOSTER PISTON Abstract of the Disclosure A vehicle wheel braking system activated by a master cylinder is provided including a rotor connected to a vehicle wheel, a bracket having a position fixed with respect to the rotor, and a caliper slidably mounted with respect to the bracket in a plane generally perpendicular to the rotor rotational axis. A first hydraulic cylinder activated by the master cylinder is connected with the caliper. The first hydraulic cylinder has a piston for frictionally engaging the rotor to restrain rotation thereof. A second hydraulic cylinder is positioned between the caliper and the bracket. The second hydraulic cylinder has a piston that is pressurized by a reaction force experienced between the caliper and the bracket when the first hydraulic cylinder is activated. A third hydraulic cylinder is fluidly connected with the second hydraulic cylinder to receive pressure therefrom. The third hydraulic cylinder has a piston to frictionally engage the rotor to restrain rotation thereof.
