Front caliper pressure

Had froze/worn front right caliper, replaced caliper but left inner washer off, caliper froze, got hot, replaced front calipers and rotors and pads, and left rear caliper to match new right rear caliper I had done few weeks ago, bled left rear first and got some really dirty fluid (black)out. Bled front right next and bled air out but didn't have a ton of pressure, bled front left last and had a good stream, firm pedal and think everything will be fine but worry about front right lower pressure when bled, should I bleed at master cylinder or the other brake device below/next to it? thanks
