Air leaking into brake lines Options

[jmargush]

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?

Never heard that before, but it makes sense.
Just curious, but is it required to periodically check/reset the clearance as the pads wear? Or is it only required when installing a new set of pads?

been discussed here in a few threads - search on 'venting' and i'm sure it'll turn up. be a good idea anyway, because i'm only 90% sure on the 0.004" number...

if your self-adjusters are doing their jobs, it's a new-pads-only thing. the venting clearance is basically the self-adjust rest-position baseline.
