Abstract
A hydraulic brake motive apparatus includes a reservoir containing hydraulic fluid. A power transmission unit selectively provides at least one of negative and positive pressure to the hydraulic fluid to generate pressurized hydraulic fluid. A caliper piston includes a piston cavity configured to selectively contain hydraulic fluid and at least a portion of the power transmission unit. The piston cavity is in selective communication with the reservoir via a reservoir passage. A motive housing contains at least a portion of each of the reservoir, the power transmission unit, and the caliper piston therein to maintain a closed-loop system for the hydraulic fluid. The motive housing defines a piston bore. The caliper piston selectively reciprocates longitudinally with respect to the piston bore under influence of pressurized hydraulic fluid from the power transmission unit. The reservoir, power transmission unit, and caliper piston are co-located proximate a corresponding brake pad.
