Near-north Ontario, French River | You say you got them released and then they stuck again? Were you able to cycle the brakes a few times before they stuck again or was is a one time deal?. Generally if they are froze up and you get them to release they will work fine until parked again, generally. Tommy could give you the proper name for the valve but it almost sounds like a quick relay valve is sticking, if you follow the lines on the trailer, there its most likely the the valve that both the blue and red lines feed into. The service line ( blue) is was sends the 'signal' to the valve that allows it to take air from the supply line ( red) to activate the brakes. If that valve is stuck, it may not be allowing the brakes to release. |
Air brakes on trailer won't release, need help.
