yeah i have a similar problem i replaced my slave and master cylinder. and i only have pressure if i pump the clutch pedal a few times. im thinking its air in the system because i didnt bleed the master cylinder by its self. but i also have a couple of questions im hoping you guys can answer. 1. i hve heard you should use the old push rods on the new cylinders? 2. do you have to bleed the master by itself? 3. what else could be causing my problem? thanks guys
