make sure everything is tight, that was my first problem.
Awk told me to put the caliper up above the master to bleed it, and it did work.
Basically push the pads right back then stick a wrench inbetween them.
Take the caliper off the disk and hang it from the grab bar with a zip tie or whatever you can find.
Pump up the brakes hold down the lever and open the bleeder. do this a few times but never let the master go dry. also keep the lid off it while doing this.
Awk taught me all this so if it works thank him haha.
if not i would start looking for a master rebuild kit.
