ABSTRACT:
A disc brake for a vehicle having a housing with a cavity therein that is divided by a thrust plate into a fluid chamber and an atmospheric chamber. A converter located in the fluid chamber includes a fixed reaction plate and a sliding plate that are separated by a plurality of balls located in variable depth grooves in the sliding plate and a reaction plate. A rotary input applied to an input shaft caused the sliding plate to rotate and move linearly as the balls move within the grooves to provides a force that acts through the thrust plate to moves a piston that is located in the atmospheric chamber to effect a mechanical brake application. Pressurized fluid supplied to the fluid chamber acts on the thrust plate that moves thrust plate and moves the piston to effect a hydraulic brake application.
