Z1 SS Brake Lines help...Good Quality?

NewYorkJon34

I recently purchased & installed the Z1 Motorsports SS brake lines. I was unsure with which brand to go with, but since I respect Z1 and they track test their stuff I went with them. I'm not sure i it was a bad bleed or what, but the petal is now pretty inconsistant. It goes down 1/4-1/2 of the way down before it stiffens up. Sometimes I have to double tap the brakes to get the pressure up to stop, which is annoying. The guy I had install these really thought these were not fully braided, which Z1 claims they are. He said the lines were expanding a tiny bit when stepping on the brake petal, which i dont think should happen. I was wondering if anyone else has installed these and if they have any info that could anwser whats going on. Im going to Nissan tomorrow to have them re-bleed the lines (3rd time) to get any air that might be trapped. If that doesnt fix it I don't know what to do Oh and btw, you need 4-5 bottles of brake fluid, not 2 as sites have suggested. 2 to flush the system out, and 2-3 to fill the tank up, hope that helps others.
