I also doubt that 44 PSI is helping your stopping ability. If there is something wrong with the hydraulic system it is always obvious in pedal feel. If the pedal feels firm and sharp instead of soft and lazy(you should be able to make the car lurge back and forward at low speeds by idling forward, braking, idling forward again, braking, etc) then your hyrdaulic system, dare i say, is working fine.
