The first Hayes trailer brake controller was invented by The Kelsey Hayes Company in Detroit Michigan in the 1950's. These original trailer brake controllers were hydraulic over electric and required a direct tie in to the tow vehicle's air or hydraulic braking system. In the 1970's the technology changed to electronic proportional controllers with Hayes again leading the way. Today's trailer brake controllers have evolved into safer and smarter systems to adapt to today's towing needs. The Hayes Brake Controller Company is now located in Arab, Alabama where design, testing and manufacturing are conducted. The company has built a 60-year legacy of making sure when dealers recommend Hayes products, that they can do so with confidence.
