So this is not going well... I drove it over to my buddies shop and had no problems at all with the brakes on the way. We put the new MC on, after bench bleeding it, bled the rears no problem, but could not get the air out in the front and the cap leaked. Went to a different parts store and got another MC. Bench bled the crap out of this one and was able to get solid fluid on all four corners, but had no brakes at all once it was started up and running. Jacked up the rear and had no brakes at all there. Jacked up the front and have brakes in the front. So, guessing it's the proportioning valve. Dummy light was not on at first, but was on after double checking the lines had no air. Ordered one up and will swap it and repeat the bleeding again.

Anyone else have any suggestions? I tend to get tunnel vision once I'm buried in a problem so outside perspective is helpful...
