It's critical to have the brakes bled properly. If you have the UFP A60 or any UFP master cylinder it also has to be bled - according to UFP tech. Two holes in UFP master cylinder from UFP in the M-cylinder I have. Also, a shock absorber in the actuator will cause the piston in the master cylinder to move quicker on the rebound when trailer slows down.
I had my issue upon light breaking....You can easily see the actuator bucking forward and backward and causing the chattering sound...per UFP - new shock, wear pads and properly bled lines.
