load-sensitive proportioning valve

A valve which regulates hydraulic pressure to the rear wheels as a function of chassis height-to-axle distance. A vehicle weight transfer during hard braking increases this distance and, via a spring or rod linkage, will close the valve to reduce braking pressure at the rear wheels; also, a heavily loaded car will have more braking power at the rear wheels
