Abstract
A brake piston assembly including a brake piston; a rotary to linear stage mechanism including a spindle and a nut; and a ball ramp assembly including a nut ramp plate and a piston ramp plate. The brake piston includes a piston pocket. The ball ramp assembly is located at a bottom wall of the piston pocket. The ball ramp assembly engages a side wall of the piston pocket so that the ball ramp assembly is maintained in the piston pocket after the ball ramp assembly is assembled in the piston pocket. Rotation of the spindle causes the nut to axially move until the nut directly contacts the nut ramp plate, and further axial movement of the nut causes the nut to move the ball ramp assembly and the brake piston against an inboard brake pad to create a clamp force.
