Recently I hooked up to a really old trailer. This trailer besides having 4 air bags for suspension, also had a small maxi (Brake Chamber, with an air hose attached) which was connected to a push rod which was connected on the other side to a cross member, right above the rear axle of the trailer. Can anyone tell me please, what was i looking at. Sorry, I do not have any picture. This trailer was OK as long it was empty or lightly loaded. When they put load on it, this maxi started leaking air (From the hole as well as the push rod side). Is there any tips / tricks to deal with it ?.
Also another trailer I pulled had a very small air bag, right on top side of the axle, above the main air bag. Can anybody tell me please what is this small one for?. Thanks

The small chamber may be for an air operated slider for the tandems. Follow the hose from the chamber and see where it goes. Does it go to a push/pull valve like this? Regardless of what it is for the rubber diaphragm/pancake needs to be replaced to stop the leak.
concdriver Thanks this.
