yes...if you read the FSM or any manual you are supposed to have a certain amount of fre play to allow for variations in the clutch material and fluid as it heats up. It would surprise you how many people forget to check the pedal after changing the clutch/slave/master cylinder as all of these have an affect on the pedal. I had my clutch professionally installed and they didn't check the pedal. As the clutch would heat up it would get harder and harder to put into gear as the pedal travel was not enough to completely disengage the clutch. Found a procedure on TT.net to fix it and it's been perfect ever since!
