Clifford,

On the rear brake tank I have a screw type wingnut drain at the bottom rear of the tank and a pipe plug at the bottom front of the tank. Any where else to look for that auto drain?

i don't remember what the exact symptoms were anymore with one leak other than i found it one day when i parked for a couple minutes without putting the park brake on and turned the engine off. hissing from the rear wheels. turned out to be a small, bigger than a pin, hole in the airline right behind the fuel tank, and in front of the pumpkin.

Air recycling at the purge was a symptom recently when i re-mounted the governor without a new gasket, and it was leaking. i kept thinking i had a leaky line, but finally took it off and put new gasket on. no problem now.

Update:

I finally found it. It is in a what looks like a crossover line near the two relay valves above the differential. I couldn't hear it with my tired ears, but my wife could. It is a hose about 2' long and will be a very easy fix. (That doesn't happen often) The hose is only pressured when the parking brake is released and we are running down the road.

Yippee, another problem solved.

David, that's exactly where i said i found mine. Glad you found it.

Now, i've got to go recheck mine. We seem to be airing down sooner than we were. About 60lbs in 5 hours after shut off and park. Oh well, always something to do in my "spare" time.

I finished the Katy bike trail and Friday I pulled the hose off and went to a hydrolic hose shop and had a new one made. Installed it, left Washington MO and drove 300 miles back to Pryor OK with no more air leaks. Finally an annoying problem solved.

I had an RTS that had a bad air compressor. It was my first bus so I didn't know much then. Everytime I shut the bus down I would hear gurgling when I opened the oil fill cap on the head cover. The compressor exploded and sent air from the coach into the engine and blew the liner and had to have the engine rebuilt. Need to check that air compessor if it leaks air into the water jacket like mine did it is imminent (SP?) that you replace it. 8000.00 mistake on my lack of experience.

Thanks Clifford,

I left the bus at a friends house in Salina OK until Saturday. We drove the truck to Pampa Tx on Monday. Hailed a bit on us at Elk City OK. We will drive the bus up to Burlington KS Saturday to another building job, but when we return to TX in 3 weeks we won't go back on US69. I'll keep Mazie's on our list.
