3B is right on target.

Just to share a couple of ideas I recently read is tapping on the caliper while bleeding helps move trapped bubbles out. Another point I came across is when the caliper bleed valve is lower than the M/C you may UNBOLT the caliper from mounting and lower it a far the the flex hose will allow....ensuring the bleed valve is "clocked" at highest point of the caliper.

Not to stir a swarm, I also read that DOT 5 is sensitive to pressure bleeding..... for what it's worth.

Good luck
