Braking system for a vehicle having hand and foot brake levers

A vehicle comprising:

• a frame;
• a straddle seat mounted to the frame;
• a front right wheel operatively connected to the frame;
• a front left wheel operatively connected to the frame;
• a rear wheel operatively connected to the frame;
• a steering assembly operatively connected to the front left and right wheels;
• a motor mounted to the frame for providing power to at least one of the wheels;
• a front right brake operatively connected to the front right wheel for braking the front right wheel;
• a front left brake operatively connected to the front left wheel for braking the front left wheel;
• a rear brake operatively connected to the rear wheel for braking the rear wheel;
• an electronic brake control unit comprising:
• a pump;
• a valve box fluidly connected to the pump, the valve box comprising:
• a first inlet;
• a first outlet fluidly connected to the front right brake;
• a second outlet fluidly connected to the front left brake;
• a first valve selectively fluidly connecting the first inlet and the pump with the first outlet;
• a second valve selectively fluidly connecting the first inlet and the pump with the second outlet;
• a second inlet;
• a third outlet fluidly connected to the rear brake;
• and
• a third valve selectively fluidly connecting the second inlet and the pump with the third outlet;
• and
• an electronic controller electronically connected to the pump, the first valve, the second valve and the third valve for controlling operation of the pump, the first valve, the second valve and the third valve;
• a first master cylinder fluidly connected to the first inlet;
• a hand brake lever operatively connected to the first master cylinder for actuating the first master cylinder and thereby actuate the front right and left brakes through the valve box;
• a second master cylinder fluidly connected to the second inlet;
• and
• a foot brake lever operatively connected to the second master cylinder for actuating the second master cylinder and thereby actuate the rear brake through the valve box,
• the electronic brake control unit selectively actuating the rear brake in response to actuation of the first master cylinder by opening the third valve and by actuating the pump,
• the electronic brake control unit selectively actuating the front right and left brakes in response to actuation of the second master cylinder by opening the first and second valves and by actuating the pump.
