Clutch pedal travel

[epapp]

Not measurably harder, by my foot gauge.

Is the booster spring the spring attached to the pedal going inside that tube right near the clutch switch?

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?
