I have recently moved from a 7.25 inch to a 8.5 inch clutch on the duratec and after a slight mishap with the spacing have finally got it working (ish). My issue is that the clutch only seems to fully release when the pedal is properly pressed all the way to the floor. If not the revs hang whilst changing gear. I am currently running a retroford bellhousing with a RWD motorsport clutch and flywheel and the retroford mondeo sourced clutch release bearing. The master cylinder is a girling .625 on a gartrac bias pedal box.
Am I right in thinking a larger bore of master cylinder would move more fluid and therefore more distance on the clutch release bearing for a given pedal movement? If so what size should I go for .650 or .700? any have any experience with this?
Thanks in advance for any help you can give me.
