By all means, test RWAL if you think you can. As a '93 chassis, diagnostics are OBD-1, and I believe there's a limited self-test you can do. We've had two Aerostars, '92 and '97. One was OBD-1 and the other is OBD-2. I haven't had occasion to try and test either, but I did have a Vehicle Speed Sensor (VSS) to bad on the '92. It took out ABS, Speedometer, Cruise, and Overdrive.
I scanned the article and it seems that if RWAL has electronic/electrical failure, it'll report the problem. But hydraulic failure, not so much. Good luck with that.
Does it also have a Proportioning Valve? Our '83 E350 did, and I replaced that too, in search of better braking. But it did not also have any form of ABS... I believe Front Disk/Rear Drum needs a proportioning valve but Four Wheel Disk does not. Belief could be wrong...
