Sometimes it is hard to get fluid moving when large quantities are removed from the system. It is especially hard to get a master cylinder started moving fluid. There are 2 tricks that may help. One is to bleed the brakes in a pattern where you bleed the farthest caliper from the master sylinder and work towards the closest caliper to the master cylinder. This means start at the passenger rear, then driver rear, then passenger front and then driver front. To "Bench Bleed" a mster cylinder you will have to get some brake lines from the parts store. You want to make lines that screw into the master cylinder outlets and curve over and into the master cylinder reserviour as close to the output holes at the bottom as possible. This bleeds the master cylinder on its own without having to move fluid anywhere else. Once you have this setup just fill with fluid and pump the pedal until no air bubbles come out of the inlet holes in the bottom of the reserviour. This fills the master cylinder with fluid and gets all the air out. Which makes moving fluid past the master cylinder easier as none will move until you get some fluid into the master cylinder which is very difficult to do any other way.

Are you sure you have the left and right caliper in the correct location?They are different and if put in the wrong place will cause this issue.

Make sure the bleeder screws are facing up on them and there towards the top.If not there wrong make sure you use new copper washers on the hoses.

Do you have abs?Also before you hooked up the lines to the master cylinder did you bleed the master cylinder by itself?Also please explain step by step how you bleed the brakes?I need all the info i can get because i cant see how you did it.
