Spongey 6pot big brakes without abs
Hey guys this might be a totally stupid question but. I just installed a Al big brake upgrade on the front of my fd 330mm and I have also removed the abs. I'm finding it hard to bleed it to make it firm. It's very spongey and can't get it to how it was. all the hard lines our out and I'm running braided brake lines without a porportioning valve. Would that be the reason why it feels like that? Is it needed. Can anyone give me some advice in what I should have installed and what I would need also.

So, no hard lines at all, just braided stainless lines throughout?
Spongy is either air, or there is so much flex line that it is causing the problem. Bleed, Bleed, Bleed.
I have found in the past that letting things sit will let bubbles migrate to the top of the calipers. Tapping can help, but time did the best good. Like going back a day later. Suddenly there was air the next day that I could get out.
Good luck.

Do do you think I need to get a porportioning valve adjustable one

Bleeding the 4 piston calipers is a real chore. I suggest a power bleeder of some sort. Tap the caliper with a mallet while bleeding and cycle the breaks as much as possible. But inevitably, you'll get it on the road and after a few miles have to repeat the task again.

So don't do this.
