i have a 1992 tt, i have a new master cylinder new slave cylinder have bleed it the normal way i have back bleed it but still no pedal anyone know what to try next before i send it to nissan. when i pump the pedal the fluid goes down, when i take my foot off the pedal the fluid goes up which leads me to air trapped, but no matter how many times i bleed it i have no resistace in the pedal.
You're bleeding it wrong. First your mate open the bleed valve with a spanner, then you push the pedal down, then while you still have the pedal down your mate tightens the bleed screw, then you let the pedal back up. You are probably just pumping the pedal with the bleed screw closed.
Have you bled from all three points? 1. Near the hicas in the engine bay 2. Master cylinder 3. Slave cylinder. I had a lot of hassle bleeding mine because I didnt know about the first one
This is what I do , 1) pump pedal a few times and hold in 2) open relief valve (fluid comes out) 3) close relief valve 4) check fluid level 5) repeat about half a dozen times or until all the fine bubbles are gone and its solid fluid only
