bad master? I assume you have check fluid? and bled the system? sometimes if you can bleed the air out and still not build pedal pressure it's a bad master, sometimes they leak out when bad other times they just won't hold pressure

could also be a siezed proportioning valve but for it to move to a position to get stuck there woudl have to be a severe leak
