I just got done changing my lines, rotors and pads, and am now bleeding the system with a one man brake bleeding kit with a vacum pump.

I have gone though a liter of fluid already and am still on the first caliper, wtf?? should it be taking this much fluid on the first caliper to get all the air out, there isnt even much fluid coming out in the hose, its mostly air, even after a liter of fluid has already gone though the system.

Please tell me what i could be doing wrong!

I am keeping the master cylender closed
