320i Clutch Issues

I have recently purchased a 1979 320i and am currently restoring it. The clutch has an issue and will not disengage. i can push the clutch to the floor with little resistance and was wondering if anyone had any suggestions as to what might be wrong. i am considering beading the clutch fluid as it has sat for about 5 years, but am unsure if that is the right choice. i would appreciate any advice available.

You can try adding fluid and bleeding the system. More likely you will find the slave or master cylinder or both will need to be rebuilt.
