When I ride my RCS and apply the brakes the motor cuts off. That's a good thing. When I put pressure on the pedals again, neither the cadence or the torque sensor starts the motor again. I have to use the throttle to engage the motor and then the sensors will work again. As soon as I apply the brakes again, the sensor no longer work. I have narrowed it down to the front brake that is causing the problem. Would this be a loose connection or faulty brake lever assembly?
