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?
