This valve was put into all cars in the late 60's when they came out with

the dual master cylinder.  It is in the system because the "average" driver

couldn't tell he had a brake failure when the pedal only went down part way.

The early ones stayed "on" until the leak was repaired, and very careful

bleeding (relieving the pressure on the opposite side) managed to shuttle

the valve half way back to center.  This gave most mechanics fits because

they would usually overshoot back and forth.  Finally the automotive

industry came out with a self correcting valve that would re-center when the

failure was corrected.
