that little bit of free play at the top is pretty much normal.....mine has about 3/4"ish...and it's got 5k on it. I think you may have had dirt somehow get in the resevore...or possibly air. But that still doesn't really explain the chunks. Just be aware, youll probably soon, within 10k have a slave change.
Wait until you have problems of 75% pedal play....meaning....you only have a usuable clutch for like the bottom 2".......it's REALLY fun trying to drive when you only have like 1" of clutchige.
I don't know correct termige, but "up top" = pedal close to you, not depressed. down bottom = pedal pushed in.
