It looks like The Pedal controls an master cylinder, similar to a car. When the pedal is depress, it should remove the brakes and press a switch that starts the motor. The cylinder does not travel far enough to activate the switch. I check the fluid level and it was really low, I refilled it and still not working. Do i have to bleed the system? I notice a bleed screw on the cylinder?

I Could not see an fluid leeks either


Thanks
