I am losing air pressure at the dash, on the secondary not brakes, which I am sure is part of my problem. Given that left and right seem to be tied together I suspect its from having different bags left vs right. I cant say that I fully understand how the 6 pack air valves work. I do have several rebuild kits and will install them in the travel valves to see if that helps with air problems.
