Heavy clutch pedal?

[Swampy]

Hey all,
Just wondering if you can give me a few ideas on what to check for, when I pulled up at a set of lights I took the car out of gear to wait for the lights to go green, when they went green, I depressed the clutch and it was alot (and i mean alot) firmer to push to the floor, It still goes into gear without any trouble and the clutch is not slipping? I am stumped at what it can be. Any ideas?

Hey dude, you have a vacuum leak somewhere. By the sounds of it is a fairly prominent one.
I suggest you find a quiet place, run the engine and listen for a sucking noise.

Most likely the Diaphragm on the Master cylinder, split!!
