Is bench bleeding the master cylinder required and, if so, can it be done without taking it off of the truck??? I have the order/technique down: Left rear, left front, right rear, right front as the manual says and everything else so that when I receive my wheel cylinders and shoes I can go ahead and get it done quickly, I don't want to be out in the cold longer than I need to. But, back to my question, is it needed? I filled it with some brake fluid when I took the old lines off and pumped the pedal a few times. Fluid came out and that was enough to tell me that it works. So, now the only reasoning that I can tell for bleeding it before doing the rest is to get all air out???? Thanks!
