Well, Andy is still on the road back to home but I got back (from another member's house, fixing his MEP003A) so I guess I can spread the great news and gloat .
I got to DRMO around 0745 with parts from Home Depot. This was a 25' length of 1/4" polyethylene tube, a 1/8 NPT 1/4" compression tube fitting and 2 1/4 NPT 1/4" tube compression fittings and a cheap 0-120 PSI air pressure regulator.. Since the deuce has dead batteries, I didn't expect to run the engine and had a little battery powered tire inflator.
I checked the brake fluid level, looked for leaks and topped it off with DOT5. Then I pulled the breather off the MC cap, installing the 1/8 NPT fitting and a length of poly tube. Put the regulator in line, then connected it to the inflator. Turning on the compressor, I noted a good flow of air into the MC. I tried the brake pedal and SUCCESS!!!!!!! Properly firm and PERFECT IAW the -23. I then relieved the pressure AND THE PEDAL STAYED FIRM AND PERFECT. There was a little drop in the brake fuid level so a top off and put it all back together.
Now for the hypothesis. When I took the breather fitting off, I noted it took a bit of mouth pressure to pop off but functioned perfectly as a check valve which would create a VACUUM in the MC which could retract the pistons at each wheel cylinder. When some bidders tried to fix the problem by bleeding the brakes, they only made it WORSE, meaning only a pressure bleeding would fix it. Or my Dr. Frankenstein fix.
We spent a bit more time, jump charging (off my car with jumper cables direct to the batteries) and even got it STARTED! Runs great, got it up to temp, drained the air tanks (dry) and checked for charging (28.1 V). Batteries even look like they are going to take a charge.
So, to sum up today? Perfect success. And the original problem of Andy? GONE!!!!
Edit to add: When did I go before the promotion board and become a junior NCO (Corporal).????
THANKS! But I would rather be a specialist as my leadership skills are less than optimum. Send me to PLDC, please.
