DEFINITION

Classification: 303/9.71

Having significant pressure control by front brake:

(under subclass 9.62) Subject matter wherein the means for varying the fluid flow is substantially affected by the amount of fluid pressure present in a fluid line connected to a fluid pressure operated, forward motor used for stopping a vehicle.

(1) Note. While many front/rear apportioning valves in tandem brake systems have a front pressure line connected thereto, significance with relation to affected apportioning valve operation must be claimed for a patent to be considered as an original classification in this subclass.
