Usually, that would result in the pedal becoming stiff or weak due to air pockets in the lines; hence, not effecting pedal free play. The problem could be a number of things from failed pilot bearing, the absence of a pilot bearing, or a faulty master and or slave cylinder. Start by inspecting the master and slave cylinder to ensure they are working properly, then go from there. The whole hydraulic clutch system is actually very basic in the way it operates, so it can only be so many things. If your clutch system (cylinders, lines, etc.) are in good condition and are moving the shift fork properly then it could be something wrong internally.
