What Joe is describing is the result of age and corrosion. I don’t know the age of his brake chambers, but I suspect they either might be original or the coach has spent time in recent years in a salty environment such as the coast or in the rust belt.
And he may be right in that the corrosion may have impacted the operation of the brakes.
But based on what he described I can make some additional assumptions. The cans on the bottom of the air bags have substantial corrosion unless they were recently changed. If he has the leans I would not be surprised if the bottom cans had porosity. The Norgren valves and their bolts were badly corroded. Especially since steel bolts holding them in place were in contact with the aluminum valve bodies.
The good news is when his project is done future maintenance is going to go a whole lot easier because he knows the process and because he won’t be fighting corrosion.

OK, great!l Thanks once again.

I would change out the fan breaker and eliminate that possible problem, as that’s the easiet one to fix. Then if the new breaker trips, you know you have a fan motor problem.

They aren’t shocks. They are part of a system called a stabilizator, no longer available that was used to keep the tail of the coach from dropping when the tag axle is lifted.
I don’t know this to be fact, but some converters, (Marathon possibly) would disable the system. I don’t know why because I had it on my 97 in conjunction with the automatic tag axle air dump when the steering wheel was turned to the extreme left or right and it kep the tail from dragging by hydraulicaly supporting it when the tag axle wasn’t contributing to supporting the rear.
I know of at least 3 coaches that have the system in addition to yours.

LOL, no I actually took typing class in high school so I use more than one finger to balance the load.
And, yes, it did recharge me. Look forward to seeing you guys. Anyone who wants help is welcome to it to the best of our ability.In reproofing over after I posted this, I discovered I should have made the same comment on batteries that I did on tires for the same reasons…i.e. mismatched and differing age batteries are a terrible thing. If any batteries need to be replaced that are in a bank more than a year or so old, I recommend replacing the entire bank, since it is only as good as the weekest link in the chain. As batteries age due to time or number of cycles, they can store less and less total energy each recharge, for several reasons. Plate material sheds to the bottom of the container, etc. Just replacing a few horrible batteries in an old bank will help prematurely age by putting unnecessary stress on the new one put in this situation. It is really a situation of “All or nothing” and shorted old bad batteries are a fire hazard as well. When we see coaches with bad shorted overheating batteries at our facility, we tell customers we won’t even plug the coach in for risk of fire or damage to charging source to the shorted bank.
