the piston seized inside the M/C. Was wondering if anyone has any tips or trick to pull it out?

I would suggest purchasing a brand new master cylinder.

Thanks for the comment but at the moment that's out of the question unless it's absolutely neccessary that I have to. (in other words I can't afford $90 for a new one).

you took out the screw on the bottom right?
just making sure, but if you did, then just try and spray some wd-40 in there and get something to push the piston in to break it loose OR pound the thing on the ground. ghetto but i find the ghetto ways are somewhat effective.
if that doesnt work, drill the piston out ( i'm assuming you bought a rebuild kit so you have a new piston) but be carefull not to damage the interior walls
also hopefully you bought an oem rebuild kit since most non-oem parts crap out on people

Yeah the screw is out, from the looks of the piston is gummed up in there. I'll try the WD-40 tomorrow.

An OEM unit from the dealer should cost you $50-60 at most if you shop around. If you rebuild it, it may leak again.

i rebuilt mine with oem stuff. no problems yet, even with my super stiff pedal pressure

WD-40 + pounding it on a block of wood did the trick
