Question #1: Will a heavy-duty "T" style pneumatic coupler work for the tow vehicle vacuum line connection or is there another recommended connector? I cannot seem to find anyone who can supply the original connector. Question #2: Can someone recommend an appropriate brake controller for the tow vehicle that will work correctly with the electric proportioning valve on the "Hyro/vac"? Question #3: Can anyone recommend a part number, vendor/source for the inline check valve for the vacuum line on the tow vehicle? I have the orginal Midland Ross part numbers but all local RV and brake system specialists look at me with glazed over eyes! That's probably enough questions for now. Thanks in advance for any assistance. Ken in Idaho
Inland RV Center, has all the remaining repair parts for the original Airstream "disc brake" system.
You can use a 3/8 inch "quick disconnect" air line fitting for the vacuum lines.
There are two controllers available that offer good to superior braking results.
They are both made by Hayes.
One is a standard model, and the other is the Genisus model, which we have provided for that brake sysytem for some time, with very good results.
We also have the check valves.
Depending on the overall condition of your disc brakes system, such as "is the sync valve ok," you may wish to upgrade the system with a new style actuator, that does reguire some additional wiring, but is not difficuolt to do, but more importantly, does not require a "vacuum" supply.
