Reply to "Brake schematic"

Note that EACH end of the shuttle valve has a shallow groove. Should one brake "circuit" fail, the valve moves to the failed (low pressure) side and RESTRICTS fluid flow to that "circuit".

Repeated applications of the brake pedal will eventually empty ONE of the master cylinder's reservoirs, but the dam within the master cylinder's reservoir will retain sufficient fluid to operate the non-failed circuit.
