My pedal will stop traveling about .75" away from the carpet. If I push harder, I can see the clutch plunger push further into its sleeve the firewall, but I can't easily push the pedal into the carpet now.

Does the spring limit the pedal travel when it's broken?

yes, it is inside a "tube" it help push the pedal down
I don't think it would limit the travel if it was broken, just make it harder to push and would come up quicker/harder
