the front brake on my 00 yz250 is hardly worth calling a brake at the moment and I cant figure it out. the whole front end is from a 01 yz125 and i know the master cylinder was a little different from 00. The overall feel is spongy, but there is pressure in the lever, just low stopping power.
started with fresh pads. The old ones had some time on them but weren't wasted. The rotor is good as well. This helped alittle, but i think its just cause the fresh pads have more bite.
The pistons move in and out like butter.
bled. filled with fluid and bled again, tapping the MC and caliper with a rubber mallet to make sure there was no air bubbles.
what do you think it could be?

I had that spongy problem in my old Honda. It ended up being that I needed to rebuild the master cylinder with some new seals. You should be able to find a rebuild kit on Motosport, BTO or Rocky Mountain...
