i just changed the calipers and rotors before everything was fine i cant get the system to build any pressure i have bled the brakes several times???
the pedal just goes to the floor, any possible problems

Did you bleed the rear brakes too? Make sure the reservoir is completely full when bleeding or it could suck air.

found problem

when i put the calipers in, they were dry. the zert is at the bottom of the caliper so when the fluid is pumpmed in through the middle of the caliper. it left air pockets at the top. i took them off flipped them up side down so the zert was at the top then bleed them tell the plungers moved out and pushed them back in with the zert open while maintaing pressure tightened it. put it all back together and worked like new.

Yessir, air rises to the top and you're not the only ones that's happened to. Glad you figured it out.

Did the same thing on my dually. emptied 2 bottles of brake fluid before we figured it out.:rof

I'd have to check, but the bleeder screw should be on the top, should be a left and right caliper, and it sounds like you have them mixed up

yep, just did a google search, they are left and right specific, if your bleed screw is pointing down, you have them mixed up
