I posted recently about my junction box replacement. I seem to have that all squared away, but I can't seem to get rid of my spongy pedal. I've bled and bled the brakes, and no bubbles come out at the calipers. Of course, while replacing the junction block all the fluid was emptied out of the master cylinder, reservoir, and brake lines. Do I need to bench bleed the master because of air that's now trapped inside?
