  • Hydraulic brake - Wikipedia

    The braided wires have negligible expansion under pressure and can give a firmer feel to the brake pedal with less pedal travel for a given braking effort. The term 'power hydraulic brakes' can also refer to systems operating on very different principles where an engine-driven pump maintains continual hydraulic pressure in a central accumulator.

    The series circuit in Figure 12-17 has the outlet of the first motor piped to the inlet of the second. This series circuit gives nearly perfect speed synchronization, but reduces each motor's power. The series circuit works well with hydraulic motors because outlet flow is almost identical to inlet flow.
