I don't think it's electrical. One of your brake sensor switches may be set too tight. There's a manual adjustment on the front brake lever under the reserve toward the front. Don't know where the rear brake on a Hannigan is, but it's there somewhere around the reserve.... Also thinking the spring on the foot pedal may be weak and the weight of the pedal causes it to bounce??
