I recently had a brake problem that I was able to take care of, but I had to bleed my brakes. I didn't have a vacuum pump so I did a reverse bleed from the caliper up to the master cyl. It worked, but I still had some air in the lines and no amount of "turn the valve, engage brake lever" was getting it out.

I read the tip "brake bleeding made simple" and gave it a shot - it worked like a charm!

thanks for the info!
