Stop in for a cup of coffee

Pulled the master yesterday to bench bleed it. I was fine with the melted reservoir and I changed the reservoir out then no pedal at all. Tried to bench bleed it and cannot even get the plunger to move. Wonder what is in side it to hold it up. Sucks it is a dr diff one with a ss lined bore. Gust got fed up yesterday and walked away.
me confused - I thought you bought a new one..
