My clutch has been losing pressure lately. When it does it wont start disengaging until about 2/3rds down and I have to bang it in gear. It also hangs downs in the travel. If I lift up on the clutch pedal with my foot, pressure comes back in a few seconds and it shifts fine. The pedal bracket isnt loose and I have the right amount of freeplay when the clutch is working. B16 with Y21 tranny.
