Stranded in Georgia

[Roland Trombley]

Thank you Brett

[twinboat]

Did they bypass it for proof of problem ?

If that don't fix it, I'd be looking at the steel branded hot line from the compressor.

[Roland Trombley]

They are going to replace the braided line along with the dryer

And then you'll be on your way home!

[Roland Trombley]

Oem replacement dryer on order to arrive on Thursday. Fingers crossed.

[Unplanned Tourist]

Great to hear you are getting some action Roland.

I agree that a new replacement air drier is a great idea.

Did the mechanic reach under and feel for air escaping from the drier purge port while it was doing the slow build? I hope so.

[Roland Trombley]

There is some leakage at the purge port, but not a lot.

The tech that found this in the dryer two days ago found this inside.

They come in many shapes. Grab an assortment and see what fits.

We are on our way to Florida in our 99 American Dream diesel with 43000 miles.
After pulling off of I75 in Cleveland, TN for a rest break, I lost pressure to my air brakes.
A local tech was sent out by Good Sam, who looked everything over and said I had been on the brakes too much and I should continue on my way (I'm trying to make this brief).
So we drove another 89 miles to our overnight destination in Acworth,GA.
While maneuvering in the campground my brakes locked up from low air pressure and it took me an hour to build up enough pressure to move it into our space. A mobile service came and found a deteriorated filter in the air dryer, which was to have been checked by a service garage before we left on our trip. They also determined that the governor was defective and replaced it.
When testing it out it first appeared to be working perfectly, with pressure building to 125 very quickly. But after several cycles of test braking, the pressures failed to recover past 60 pounds.
So they checked further and found an issue with a sticking unloder in the compressor. They were unable to get a new compressor until late next week, at which time they had already scheduled work with their regular truck customers. So they did not bill me for the parts, and their labor rate was very reasonable.
Now I am faced with the prospect of having it towed, possibly to a Campers Inn service location nearby (6 miles).
I'm debating whether or not to attempt to drive it there in order to avoid towing. I'm more concerned about potential towing damage to my pristine old motorhome than I am about the cost of towing.
Does anyone have any thoughts they would care to offer?
Thanks in advance.

Try and find another truck mechanic/shop. The air compressor unloader valve is repairable/replaceable without replacing the compressor. An old school mechanic would probably just clean the unloader, replace its parts, or replace the unloader, Not the compressor. Also when the dryer was serviced they should have replaced the purge valve. If it sticks open you'll have a hard time building air. Ask around and get another mechanic to look at this.

A couple of random notes:

There are no "standard" air couplers. I tried to find out from several tow truck guys, even, what coupler they use to connect to my coach and they couldn't give me a spec. I've got a half-dozen different quick connectors in my toolbox, and none fit.

I got around it by pulling the existing (but unknown) female connector from the coach air line and reinstalling it on a Tee. The other side of the Tee has a type "C" female connector, which plugs in to my aux compressor and all my air tools. That way the problem is solved and the tow truck guy has his air port, and I have access to the on-board compressor for my air tools. For my emergency purposes, the pancake compressor was in the basement with a hose running forward to the Tee. I powered it from the basement freezer outlet, which runs off the inverter.

The other note is that when I did the air fitting Tee to suppliment my compressor, I was in a similar situation (might still be there) as the OP. I found that the (Freightliner) dash control module was bad. I forget the name of the controller, but it sends signals to the dash gauges. It was throwing all sorts of strange pressure readings and setting off the low pressure alarms and lights as I went down the road (no brakes in use). Even with the aux compressor running I was getting constant pressure alarms. It was quite unnerving.

When I got to a good place, I checked the actual air pressures with a gauge and discovered the gauges and alarm were the problem, not my air supply. I tinkered with u-toob fixes for the failed pressure sensors but was unsuccessful. When I replaced the controller (ebay), the dash gauges agreed with the test gauge and the alarm started behaving. I haven't been on the road enough since to see if my compressor's recovery time is good or not. What I'm saying is that I could have other issues in addition to the dash controller. I'm not assuming it's completely fixed yet.

Hi I saw you post about loosing air pressure. If you have to be towed. I hear anything over five miles you should disconnect the drive shaft. If you have towing on your insurance policy use that. Progressive was great. If you are using that portable compressor your may have to use a reasonable size. That may cause your average 15 amp outlet to trip. You may have to plug into a 20 amp outlet. Good luck hope it helps.

Unhook the driveshaft if towing irregardless of distance.
