  "textContent": "A controlled brake apparatus and method of operating a brake apparatus utilize a pre-charge circuit (88;94) connected directly between the fluid reservoir (16) of a master cylinder (12) of the apparatus and the inlet (42) of a controlled braking pump (40), to thereby direct pre-charge flow and pressure to the controlled braking pump inlet (42) in a parallel circuit relationship to a primary hydraulic circuit, rather than in a series flow arrangement through the primary hydraulic circuit (88;94) as was the case in prior brake systems. The pre-charge circuit includes an integral back-flow check valve (46), and preferably an accumulator (48).",
