Flushed the lines today using alcohol. Bleeding the front passenger side I had millions of micro bubbles. I did almost an entire quart of brake fluid through that side and still had microbubbles, however I think this may be from the bleeder sucking in air from around the threads. I'm not sure, I ran out of brake fluid to bleed.

It is still doing the same thing, to a lesser extent. Pass front wheel was significantly hotter than driver front wheel after about a 5 mile drive. I may replace the passenger front caliper (under warranty).
