ABSTRACT:
A vehicle brake mechanism having a foot pedal and hand lever brake controls engagable by the operator and coupled with a generally transversely extending shaft pivotable in response to the operator engaging the brake controls, left and right linkages coupled between respective vehicle brakes and the transverse shaft, and shiftable generally with the transverse shaft for applying respective vehicle brakes. Left and right equalizer mechanisms are coupled between the transverse shaft and respective linkages for generally equalizing and balancing the forces applied to each vehicle brake. The linkages include a rod. Each equalizer mechanism includes a pair of outer levers extending from the transverse shaft for pivotal motion therewith, a spacer slidably carried on the rod and abutable with the lever as the lever pivots with the transverse shaft, a compression spring compressed between the spacer means and a first washer means coupled with the rod, a second washer coupled with the rod and abutable with the spacer when the outer lever has not pivoted from a brake disengaged position. The transverse shaft is pivotally coupled with the vehicle at two laterally spaced locations.
