Quote: It was brought up once before but I don't recall what was said:
Does a typical Mopar master cylinder have a certain amount of natural "proportion" built into it? In other words, would there be any difference in front-to-rear pressure without a proportioning valve......and would swapping the lines at the MC change it front-to-rear, if needed?
A quick test while bench bleeding would be, once you get it bled put the 2 lines(that you have going back into the res) bend them over so you can have them squirt into 2 measuring beakers... if its a different volume its a build in prop valve
