Will you savy mechanics please enlighten me on this process! Everything is new, new calipers up front new lines, new master new prop valve, new cylinders in the rear, new lines on the axle. Only old line is junction from passenger front to axle. I bleed the master on the bench. Every wheel will bleed but drivers rear. New bleeder back there. I've tightened everything to the point of breaking them . The drivers rear will spew bubbles indefinitely. This tells me I have a loose fitting right? But passenger bleeds bleeds fine? Bad wheel cylinder even though it's new? I even bought a little bleeds screw thing for the proportioning valve. I dunno but iam about to flip out mood. Any insight of any kind will help cause iam looking this battle. Thanks charlie
