Clutch pedal on the floor

I have a 87 944 I've owned for a month. 65k miles. Clutch master was replaced 3weeks ago under P mechanic's advice because pedal occasionally went to the floor. You could pull it up with your toe and get underway, once warm it would go away.

Hadn't driven for a week, so started right up tonight, but the clutch pedal is on the floor again. There is no tension at all, you can pull it up with your toe, but it will snap to the floor again the moment you touch it. Needless to say, can't drive the car.

What am I looking for here???

probably failed clutch slave or a bad hydraulic line between master and slave.

or maybe something mechanically wrong with clutch fork/throwout bearing/pressure plate fingers?

yup - most likely the main hydraulic hose - they balloon up at the coupling and then rupture

always change all components in an hydraulic system at the same time - failure to do so will quite often result in the remaining component failing, as it is weak

Luckily the clutch is bleedable with 1 person if you have long arms.

look to the line between the master and the slave, but first be sure it is bled

Quick test - pop the clutch inspection plug off. If you take a bath, the slave cylinder is ruptured.
