Abstract
A double, disc type brake system for wheeled vehicles, including two disc packs, operationally combined in a working set, for each vehicle wheel to be braked, the disc packs in each set being respectively placed in back to back relationship, and the disc packs having hydraulically operated multiple pistons for actuation thereof, the multiple pistons constituting two oppositely faced piston sets operatively positioned in a common actuator support centrally disposed between the two disc packs of each set, and the two piston sets being respectively operable to actuate the two disc packs of the set. The hydraulic system is operable to initially actuate one disc pack of each set upon movement of a brake pedal through a first increment of application for light braking action, and to inclusively actuate the other disc pack of each set upon movement of the pedal in an additional increment of application for increased braking action.
