[Spridgets] Mighty vac bleeding

[CosmicMag1380]

Respectfully  disagreeing with the terminology... There is a 5 port union
in the system that has a shuttle valve in it to close off a side of the
system in the event of a catastrophic failure. They came about with the
advent of disc brakes on the spridgets. The later models had a warning
light sensor built in to them. The early ones didn't have the light
fitting. They are often referred to as a proportioning valve as they have
equal pressure on all ports until a sudden fluid leak and a good stomp on
the brake pedal. If the pressure is low on one side of the system, the
shuttle valve is supposed to close off the bad side leaving some braking
capacity because of the other side. One front wheel and the opposite side
rear wheel makes up the pairs.

Just my 2 cents if it means anything to anyone,
Kent
