    Sounds to you like an air leak behind the dash. You hear it in the dash and can't find it on the truck. If you have something pressed on the brake pedal and you got outside and went down the rig, you would find it easily. Oscar and Superhauler called it right. The little diaphragm in the chamber goes bad and air leaks air from the parking brakes side to the service brake side and forces air back through to the valve in the dash.

    Sounds like a blown maxi, air up everything, put the truck in gear shut it off or chock the wheels whatever to make it safe. Then release the brakes. Look at all the maxi brake chambers they will have four little holes with air leaking out.

    I met up with another driver and I held the trailer brake and he listened, nothing. Then I held the service breaks and he found the leak.

    Turns out it had nothing to do with switching the lines, one of my lines was rubbing on the differential and chaffed a hole.

    Thanks @Oscar the KW and @superhauler for the prompt and accurate advice. It's in the shop while I do a rollback load.

    Yea I keep a set of tools with me even though I'm only a company driver and we have a full time garage and service trucks and run local. I wouldn't have been able to take down that street sign last week without it and would havebhadnto tear it up and look unprofessional.

    But I never liked mechanics. When I was in my early 20's, I always loved the 83-87 Monte Carlo SS's. Well my second one that I bought had a 350 in it, so I decided to slowly build it up. So I decided to install headers on a weekend with my cousin and backyard mechanic.

    Well we snapped a bolt on the very last bolt closest to the dash. He ended up having to tap it out, then take out the head, take the head to a welding shop to tap and die the head, reinstall everything. Then I had to drive the car 2 hours to rhe nearest muffler shop to get the headers connected to the exhaust pipe.

    Whole thing took 3 weeks and that was my daily driver. But I'm cheap and hate paying a mechanic shop so I try to find friends that know how to do it and drink an adult beverage while they fix my car.

    But if I want to own a truck one day down the road, I know that I will be a lot more successful if I can do more things on my own. When I was with the smaller company, I volunteered to standardize all the hydraulic hoses on our fleet to one size fitting so all trucks and trailers could be interchangeable. I also volunteered to plumb and wire the air compressor setup.

    Someone once told me you got to dress for the job you want, not the job you have. I may be a comapny driver but I am in training for the next level whatever that may be.

    Yesterday when I went to go pick up the screen, I took our trailking that has a 4th axle on but it doesn't have a lift on it. There are no attached chains either so you would manually have to rif up some chains if you want to run with it up.

    I wasn't going that far empty so I just ran with it down. But the third axle has a lift on it. Would I get a tighter turning radius with it lifted or would it cause problems like a spread axel flatbed / stepdecks?

    I run like that all the time when it is a quad. Sometimes I turn off the air to the 4th axle and chain it up it will have a shorter turn with it up.
