On my 1140 I notice when going down the road the airbags on the pusher spit alot. I have had to push hard on the brakes from time to time and the pusher always locks the wheels. I am wondering if there is a adjustment to prevent the air from escaping so rapidly. This also causes my air compressor to cycle more frequently going down the road. I know this is not a equipment thing but thought I would post it here since it is a miller spec truck. Any advise would be thankful.
