Older Air Suspension ?s

Good info, thanks.

Reading up on what I have, it seems that the air bags and the compressor are not related to each other. The air compressor, its tank and brake actuator valve I think are part of an older Roadmaster towed braking system called the BrakeMaster. Originally intended for MHs with airbrakes it could be adapted to work with hydraulic braked units like mine with the addition of a small air compressor. The unit is described here half way down the page: LINKY. I don't think it was ever intended to be part of the air bag system, not that it can't be. I think with the addition of a tee like you mentioned, I will get more use out of the unit as an inflator not only for the suspension but other small items.

I know that's an air line quick connect, but why is it there when I have these



in front of each rear wheel opening?

I don't see an onboard compressor or air pressure guages anywhere.

I guess my questions are, what is the point of this system and how do I operate it?

TIA,

I have a 2005 254 Touring Sedan. Mine has Firestone air bags that are filled via an air fitting on each corresponding rear fender. They are manual, fill to aid rid while loaded. They can be filled between 5 and 100 lbs psi. Mine lift the rear end a couple of inches and really stiffen the ride.

Thanks for the info. I was curious as to who the manufacturer was. Your system sounds like mine.
