If the long RB TPA bolt has reached the master piston, and is pushing it in, then the only reason why your pads arent moving is the bleed.
If its not reaching the master piston, screw it in more :ermm:
About the bottoming out, i had the exact same problem and ended up just selling my rb lever. I think the only solution is to have the pads quite far from the rim, and screw the TPA bolt in so much that the main lever big (that holds the brass threaded bit) doesnt hit the side of the master cylinder.
The pads sahould move instantly when you pull the lever (if its pushing the master piston). If not, its the bleed basically. What are you bleeding with? id recommend water, and clean all of the bits seperately first.
And like jon said above, take the seal bit out and give it all a good clean.
