Ok so I can't get my big brakes to get the right pedal feel or to hold pressure. Anyway I bled the crap out of them 3x's in which 1x I bled for a straight 45min. I'm running evo 8/9 fronts with z32 rears(no hand brake) the bmc was working 2days before I believe it's a 15/16 z32. Lines are new(installed same time i installed the calipers) and banjo bolt connected. The brembos were from the manufacturer and looked great(seals still good). Was told only had 500 miles on them. Even after the bleed I couldn't figure it out. I don't see any brake fluid leaking anywhere also. Anyone help me out?

Did you bleed both ports on the calipers and are the brakes installed right with the ports pointed up?

I bled both ports and they're pointed down because I saw that in 2 other write ups they're down.... But I did notice on egos they're up.

they need to be up and who ever did that in their write up is an idiot, flip them over since air naturally wants to go up, it will be impossible to bleed them upside down

Also this the bleeder nipple has to be on top. I think the caliper even has an initial on it R or L

That's what I thought...I thought I put them on backwards so I read on here and on nicoclub 2 write ups and they both were facing down...smh

No I didn't bench bleed my bmc it was working just 2 days before the conversion and was installed already when I took my z32's off. I feel bench bleeding would only be needed when changing a bmc no? Correct me if I'm wrong.

Now that I redid my search it seems like skull works and tf have them up...thanks ill try this out tonight

Seems like all is well now after I switched the calipers. The car isn't running so I can't test em.
