Is it really necessary to do so? Since air wants to rise into the m/c, and if you use the Pheonix System reverse bleeder, wouldn't the brakes be perfect? I gotta hear some thoughts on this, might get that tool.
I didn't bench bleed mine and my brakes work just fine. May have taken a little longer to bleed the brakes but I put new lines on also. Figured it was going to take awhile.
