started with the one farthest, so RR, LR, RF, LF. Then looked through the Bentley manual and it had some other sequence so I did that as well. No difference. Pedal is spongy and soft, not low and firm. Finally got my air compressor hooked up tonight, so tomorrow i'm draining all the fluids and removing/cleaning the bleeder valves, running some denatured alcohol through the system, and blow it through with some compressed air. Then start the whole process again. Hopefully this will be it.

Lines are all steel, at least the ones going to the calipers. Not rusty at all. Car has ~103k miles and gramps has owned it since '91. It's the cleanest 18 year old daily (well, maybe every other day) driver that I've seen.
