Well, back on topic here.
Got the car back from the shop. The brake lights started working as soon as vacuum hose was hooked up again (yes, I was right about that, thank you) and the vacuum hose was disconnected and could be reached from inside the car (yes, HH, you were right about that, thank you). The new accel pump improves driveability a lot. Around town, taking it out of OD also helps driveabiliity because you get engine braking.
I need all the braking I can get. It seems the new shoes are wearing in nicely. There's not much complaining coming from them any more, and the car CAN stop straight and smooth.
However, I have a case of EASA-FADE that has me perplexed. I don't expect modern-style stops, and it stops pretty good most of the time. But just following a slightly harder or longer stop, the same pedal pressure doesn't come close to being able to stop the car.
Do the brakes possibly need to be adjusted tighter due to things "stretching out" after a long time of no-power-assist braking? Or could it be something else? I don't believe it's normal fade.
BTW, the vacuum hose was still OK, and the mechanic put a zip tie on each end of it. I think that might've been a good solution... no metal to chafe against the hose. Kind of clever, although some may, of course, disagree. Remember though, don't be too harsh as I am STILL not an expert, and don't believe I want to be one.
Finally, the mechanic noted that there is some brake fluid drawn up into the rear part of the MC. It comes from around the main rod from the pedal where it enters the MC. Other than losing some fluid, I'm wondering if this is part of the fading problem-- as MC gets used harder, some pressure is lost as fluid seeps through. Warmer fluid seeps more, more pressure is lost until bigime fade... again not an expert on this.
Sounds like more $$ to me, though. Detecting when that's the case is my real expertise.
