@mac - yes, I'm getting normal bleed pressure out of the master cylinder & all the bleeder valves/calipers.

What the problem sounds like when you make a drastic change in a brake "SYSTEM" , now with oversize calipers AND it sounds like you now have MANY MORE PISTONS ?? What that will mean is the master cylinder wasn't designed for THAT much more fluid VOLUME your "NEW SYSTEM " is now demanding - and now your simply shocked at how much PEDAL TRAVEL is now needed !! I mean DOES THE CAR STOP SATISFACTORILY - but it DROPS WAY DOWN to do so
This is what I'm wondering also, could the upgrade, since it does require more fluid be the issue? I would naturally assume since I bled the entire system and there is pressure and no air bubbles that regardless the size the master cylinder it would be sufficient to push the brake fluid thru the entire system?
To keep your oversize calipers looks like you gotta get a m/cyl that can pump the increased VOLUME , whilst keeping the travel closer to your "stock feel", I think this is it ??
Of course this is with the assumption a m/cylinder is not part of the kit , or wrong part #,I don't know Akebono Big Brake Kits CONTENTS ,now. I didn't notice you listing the whole shabang ,watcha get ya know.
So during the bleeding process the brakes are firm, but once i turn on the car they go completely soft, and I can push the pedal all the way down to the floor. I haven't driven the car like that, it kinda scares me with that amount of brake pedal travel if the car would even stop...

Op did you install your calipers the correct way ? The bleeder valves have to be facing up. couple of years ago there was a post about this and the person claiming his brakes were spongy had installed his akebono calipers with the bleeder screws facing down. I installed my bbk years ago
and I never hd/ have any issues. my brakes actually require very little pedal pressure to stop on a dime.
No, not all the bleeders valves are facing up. The Left front and rear are facing up but the Right front and rear are facing down. This is how they were sent to me. Do they all need to be facing up?
