Rebuilt the master cylinder and caliper this week. I top up the master, pump, open bleeder, hold down the pedal, shut bleeder, release pedal to no avail. I have tried using a syringe filled with fluid to force fluid up to the master, and saw quite a bit of bubbles pop at the surface but still no resistance at the pedal. I've noticed while having the bleeder open a small amount of fluid comes out where the bleeder and banjo meet, Normal or something I need to address? Anything else I should try? I am using a tool like this as well. Bike is a 2016 125SX.
If you bleed everything and still don’t have a firm pedal/lever, you can also zip-tie the lever back, or weight the pedal, with the bleeder closed, and leave it overnight. I’ve gotten two front brakes this way that refused to firm up no matter what I did.

Small kit and 10 minutes and you will have pressure again.
Air gets trapped in the line. The air will travel up to the caliper and out the bleeder. It easier with 2 people. Good luck.
also try zip tie`n the pedal down and leaving it overnight ive had a few difficult ones in past and this helps get it started so you can do the normal bleeding process

My adjuster for the front caliper was up too high. Turned it down some, pumping started.
