Bench Bleed Master Cyl Question

Like TB says; you have to use your finger tips to act as valves, so the fluid doesn't just shuttle back and forth thru the compensating ports. You have to do this on the bench, cuz it will be far more difficult after installation, and probably messy, and, Dot-4 or less brake fluid eats paint.
The residual valves go in the lines that operate brake shoes. Lines to discs must not have them, else the pads will get cooked. In a factory Mopar, the frontmost reservoir gets plumbed to the rear brakes.
