I'm stumped. All new hard lines, soft lines, wheel cylinders, and on a second master cylinder from Summit.

I pulled a rubber line on the front and was able to draw a solid line of fluid from the hard line; I then placed the rubber line in a container and was able to pull solid fluid through it. I put it back together and I can only get a trickle from the front bleeder screws. I can't imagine I need a thread sealer on the bleeder screws!

Is it possible there is an issue with the junction block not working correctly? After all of this I still have to pump the brakes multiple times to build any pressure, it makes 0 sense. When I bled the rear I was able to pull solid fluid, at least one side.

There are no leaks yet I can't pull a solid line at the front wheels. F'n baffled.
