Brakes caliper leaking brake fluid in Nissan Hardbody?

think your not telling us something. when you removed the capilers. did you let the fluid run empty in the master cylinder? if you did. you will have to bleed the master first to build up pressure and get the air out and then you can start to bleed the rest of the system. when I bleed the master cylinder I connect the two lines from the master cylinder and make two junk lines to go into the resvior. this saves filling the container over and over. and when you stop seeing air bubbles you got it perfect. then connect the lines back and start bleeding then calipers again. don't run low on fluid. huge mistake and lots of extra work.
