Demco/SMI actuator repair February 09, 2024, 08:51:00 pm The most common failure of the Demco tow brake unit is a broken cable on the air actuator cylinder that is mounted on the brake pedal.Etailer now carries a repair kit that isn't too hard to use and a lot costs less than a new air cylinder.Demco/SMI actuator repair | Flickr Air cylinder repairAir cylinder repair kithttps://www.etrailer.com/Accessories-and-Parts/Demco/DM56VR.htmlComplete air cylinder...yes it's expensive!https://www.etrailer.com/Accessories-and-Parts/Demco/DM6215.htmlLarry 1 Likes

Re: Demco/SMI actuator repair Reply #3 – February 10, 2024, 07:27:46 am I repaired my Stay-in-Play Duo's air cylinder with this kit. If you have an older cylinder you may have a bit of trouble disassembling it. Once you have replaced the cable on an older cylinder you don't have the same problem with disassembly; removal, repair and replacement takes under a half-hour with the cable in hand. I carried a spare cable.If you mount the cylinder too close to the firewall the cable develops a kink, and eventually breaks there. The second time the cable broke I moved the cylinder away from the firewall by reversing the mounting brackets. That should have reduced or eliminated the kinking. I don't know, as I've sold the car.Mark H. 1 Likes
