2010 mazdaspeed3. my clutch lost pressure. I figured bad clutch. So I put a new nice clutch in with New oem master and slave cylinder. (The old clutch wasn't bad) So when I get my car back. I have like an inch of clutch pedal. A couple weeks driving like that and I lost clutch pressure. On my 3rd set of master and slave cylinder now. I can't get fluid to really pump out of the bleed screw. With an air compressor bleeder pump I can get fluid slowly to come out but it's never enough to get clutch pressure back. At most I'll have some pressure on the clutch when I push down on it but it won't come back up . I can't get enough pressure to even put it in gear. I have checked the 1 line that goes to the reservoir to the slave and its clear inside and no cracks that i see. I have checked the reservoir with the feed line off and the master cylinder pumps it out. Anyone have a clue what's going on? Should I replace the reservoir and line?
