Hi there simple question.. i trying to figure it out by myself moving the pedal rounded knob coming from the clutch master, because i change my clutch with flywheel, a convertion kit from valeo and was amazing results... but i see a video posted here a old men change a clutch and said about moving back for close the valve and if you moving forward the valve are open BUT for bee honest the technician change my clutch left the valve open, because i can push with my hand the slave, and my clutch work better than if i close the valve because if i close it the clutch its feel like keep a long distance up for you feel the clutch desangage.. you know.. i ask what really do moving down the dash the pedal knob?? ( the adjuster) moving toward the firewall and moving back the knob ..? Hopefully you understand my question and yes after the tech left my car that same day i try playing with the adjuster knob moving back and forward and i dont feel like to much differences and i beleved i feel better if its open like the old guy said in the video o slack position like he said .. and yes the clutch was change in front of me because was in my garage
