UNSANE

The Loadmaster trailer my Fountain came on was really never used and sat around for a while. So what happens is the actuator sticks forward when stopping and sometimes sticks a brake or 2 backing down. It does brake loose when I get going again, but it is annoying as hell. At least it's not like my last trailer in which the brakes weren't working and nearly caused a major accident Anything easy I can do to clear this up? thx.
