Abstract
A braking apparatus and method are provided for applying a braking force to the inboard and outboard sides of a brake rotor, through the use of a pair of pistons disposed in a back-to-back relationship in a cylinder bore of a housing, and defining a space between them in the cylinder bore for receipt of a pressurized fluid. The rotor is rotatable about a rotor axis, and the cylinder bore defines a bore axis extending parallel to the rotor axis. A first piston of the pair of pistons is slidably disposed in the cylinder bore for movement in a first direction along the bore axis toward the inboard side of the rotor for applying a braking force to the inboard side of the rotor, and the second piston of the pair of pistons is slidably disposed in the cylinder bore for movement in a second direction opposite the first direction along the bore axis for applying a braking force to the outboard side of the rotor. A movable bridge element is slidingly attached to the housing for transmitting a braking force from the second piston to the outboard side of the rotor.
