I did bleed them as a Shimano, from the caliper to the lever, and then closed the caliper and pump the lever to get some air bubbles out, still spongy. Then just filled the reservoir and let the air flow trough the hose, caliper and then out again, more bubbles out, less spongy, repeated several times, felt better but not as i wish, because i don´t like to have the reach of the lever too far from the bars ( im a Shimano guy ).
What i feel is that the diafragm may be not in very good shape, or the interiors of the lever body as well, really really hate .dot oils, mineral should be a law.
Will try to leave the lever pressed for a few hours too see what happens.
By the way, i used dot 5.1, will dot 4 be better?
