Another clutch thread

[Toddles]

Hey guys

Today i was stationary at the lights. Clutch was in, I put some extra weight onto the clutch pedal and all of a sudden I hear a loud clunk. Thinking wtf? I take my foot off the clutch slightly and stall it. So i restart and the clutch is about 1/4 of the size it was before and soft, the release point is just about on the floor. Now what have i done?
Pressure plate - Master slave cyclinder??
I drove it home but very hard to select gears like the clutch was not engaging. Ideas?

Anyone know of somewhere open tomorrow? Being a long weekend looks like I wont be able to get someone to look at it till tues No more pwrx cruise

Cars a 2000 WRX

Cheers
