Re: Why isn't Bendix TV as sensitive as it used to be?

They are oversensitive when there is something wrong! There is a diaphragm inside the power piston which is supposed to give pedal feel, and make some compensation for changes in engine vacuum. If that is breached, or the passages to it are blocked you get a sort of on/off braking experience. Also, on the types used in 55 and 56 with the small poppet valves controlling the vacuum, poor pedal feel can result then their little rubber seals begin to fail.
