I've had ongoing problems with a pair of Avid Elixirs (yes, *those*) and I'm about to give in. But, something's bugging me - I've been through the bleed procedure countless times and the rear brake feels fine at first but always loses pressure almost immediately with a few good squeezes.
The only flaw in the bleed comes on the final step of depressurising the lever to suck out any air, at which point bubbles never stop coming out. I guess some seal-or-other is gubbed but the bit that gets me is if I press down on the syringe hard there are no leaks, which I'd expect if a seal had gone. Can anyone offer any insight before I lose it?
