I have a question concerning the clutch master cylinder and the slave cylinder. I have just recently upgraded the pressure plate to a Hayes diaphram type and a hayes disc which are 11", I'm not getting enough travel out of the slave cylinder, it's only moving about 5/8" and not enough to disengage with the pedal fully depressed. Any ideas? Some folks say that I need a master cylinder with a larger bore to move more fluid. Someone has had to do this swap before and been successful! Please help.
