I decided it was time for a new clutch pack and got the plates swapped out no problem. When I went to replace the pressure plate it wouldn't quite go on all the way. After messin with it I decided to pull the lever to see if the slave was just a little stuck or something and couldn't budge the lever one bit. Its rock solid. I'm thinking someone was pullin on the lever when I had the clutch apart (did the swap over 2 days got pulled away when it was apart) and now I need to bleed the system. Am I right on this? Do I need to drain it out or just bleed it back a bit and then top of the reservoir?
