1999 F-550 clutch problem

[JFA_Spyderman]

Yo,
I've got a 1999 F-550 with the 7.3l, and when ever i push the clutch in, the first half of the stroke feels fine, but then it just gives way to the floor. Not like a spongy push to the floor, but a fall without resistance to the floor. I was leaning towards the master cylinder but wanted to know what you all thought. Thanks!

does the clutch work normally?

[JFA_Spyderman]

Yo,
It feels like it works fine for the first half of the pedal, then about half way down it just drops to the floor. Another FYI is that this system is standalone, so no vacuum assist. Thanks!

there wouldnt be any assist for a clutch pedal any way Does the clutch disengage properly?

[JFA_Spyderman]

Yo,
I think so, by disengage you mean when you take your foot off the clutch? If so, then yes. I can actually drive it around, just have to match the RPMs as I do. Thanks!

[mentalbreakdown00]

so the clutch does not disengage when you mash the pedal meaning let go so you can shift? I would replace both the master and the slave at the same time if it were mine or in my shop.

Yo,
I was leaning towards the master, however I did not want to bleed the system twice, so I just replaced both, runs and shifts great. Thanks!
