Nissin rear brake dilema

Recommended Posts

I'm a bit stumped over this one... on our '04 yz125, rear brake "suddenly" stops working...

So I get a rebuild kit for both the caliper and the master cylinder. Vacuum bled the system, still doesn't move the piston in the caliper. I can pump fluid to the caliper (visible when you crack open the bleeder) but has very very little psi, just enough to flow fluid but not the piston. I don't see any leaks on the hose either so that doesn't seem to be an issue....

Any thoughts???
