Abstract: A retarding control assembly for a brake valve may include a bleed line configured for arrangement between a spring chamber of a brake command assembly and a tank line. The bleed line may include a check valve configured to allow fluid flow from the spring chamber to the tank and a check valve bypass configured to allow fluid flow from the tank line to the spring chamber passed the check valve and defining a restricted pathway.
