ABSTRACT:
Linkage which extends between right and left brake pedals and a valve construction provided with an outwardly extending shiftable shaft and a pair of valves disposed to either side of the shaft. A bolt assembly passes through one end of the shaft and mounts a yoke for rocking movement, the yoke having ends equally offset from the valves. Right and left substantially identical linkages are employed, each linkage including a push rod mounted for limited adjustable sliding movement in a trunnion carried by a bifurcated arm of a bell crank. The other bell crank arm is connected to an end of the yoke by a ball joint assembly, one end of a tubular intermediate portion being adapted to bear against a valve.
