People will tell you hot soapy water, or paint thinners, I know this 'cause I asked this exact question a few months ago, I tried them ALL and NOTHING worked. The only thing I found to get my brake working again is to re-grind. I assure you that's the only thing that'll work!
I had same problem. Bleed screw all the way in, bleed hose in the other hole, attatch pump to other end of bleed hose, pump fast/hard. Point the piston away from everything valuable/that could be hurt though.
A mate of mone has a brand new one in a box, I just can't remember who! When I remember I'll let you know so you can annoy him so much he decides to sell it!
