No pressure in the brakes after replacing both calipers

So replaced both calipers yesterday. Bled all four calipers starting in the correct sequence going from right rear caliper to the front left and so on. Yet still have no pressure in the brakes. Possible bad new calipers? Or just a massive air pocket? Even though we have fluid out of all calipers.
Do you
have the same problem?

Hello my name is Dave.

My first question is, why did you changed the calipers to begin with? Was it because of a soft pedal or a sticking brake? My next question would be, what method you are using to bleed the brakes? I have a almost foolproof system I have been using for years that is also quite fast. First thing you'll need is a hose that fits tightly over the bleeder valve, I have found that a 3/16 hose for your windshield washer works on most, you'll want around four feet. Next you'll need a drink bottle which you'll put just enough brake fluid in so that when you put the end of the hose in it the tip stays under the fluid. Next get a helper to pump the brake pedal. Now put one end of the hose over the bleeder and the other in the bottle in the brake fluid. Make sure your master cylinder is full with the cap on. Open the bleeder making sure the hose stays on the bleeder and in the fluid in the bottle then have your helper pump the brakes fairly rapidly, no need to open and close the bleeder between pumps. When the bubbles stop coming out of the end in the bottle have your helper hold the pedal down and tighten the bleeder. Repeat for all wheels and you can be sure the air is out of the system. If the bubbles don't stop and the hose has been on the bleeder and in the fluid in the bottle the whole time then you have another problem causing air to get into the system. I have found this to not only be a very efficient method for bleeding the system but also a great diagnostic aid as it will show if air is getting into the system. I would recommend starting with this procedure and see if you get a good pedal. If you don't get a good pedal let us know and we will be glad to help you with further diagnostics. I hope this helps you get back on the road again and thank you for using 2CarPros!
