I have a BB and during my trip this past winter, the actuator quit working. Although it was out of warranty, I called the company, and they had me ship it to them. They repaired it, at no cost, and it is working fine. They do stand behind thier product. My advise is to call them and see what they say. I feel that having my supplemental braking working properly is worth what it might have cost me to have it looked at by professionals. It turned out, they are nice people, just ask them. Good Luck.
