I am wondering if I might be drawing air into my brake system somewhere. I have bleed the system atleast 6 times and done all the tricks with the proportioning valve. I got a really good high, firm peadal the last time I bled them. A few days later it wasn't quite as good. then went and autoxed on Sunday and by the end of the day they were about gone unless I pumped them.

Question, if it is drawiing air in somewhere after the master cylinder wouldn't there be fluid leaking? If this is correct and I don't have fluid anywhere, the only thing left is where the lines go into the master cylinder which could draw air in without leaking fluid. Does this sound logical?

when your brakes cooled after the AX, did any of the pedal travel come back?
when you bleed with the 2-person or pressure-bleeder methods, do you actually get air bubbles in the fluid ?
what is your rear caliper venting clearance ?
