Abstract:
A hydraulic control valve for an ATV or motorcycle takes hydraulic input from a hand brake lever as an input to a first cavity of the control valve with a movable piston therein, and from a foot brake lever as an input to a second cavity of the control valve with a movable piston therein, with the two pistons being linked. A bypass channel extends around the piston in the first cavity, which is closed off when the first piston moves longitudinally. The output of the first cavity hydraulically controls braking of the front wheel(s). The foot brake lever also pressurizes a direct line to brake the rear wheel(s) that doesn't go through the control valve.
