Front brake bleeding no pressure ???

I have a Honda RANCHER 2004 trx. I started out by just wanting to replace the front brake pads..well..2 days later I went ahead and bought a new master cylinder, and each of the front brake cylinders (2 for each front wheel)...I didn’t buy the rebuild kits cause it was almost the same price as the fully assembled part.. so after putting the new master cylinder on, and all 4 of the front cylinders, I started to bleed the lines.. I filled the master with fluid, pumped the handle several times, opened the bleeder valve on the wheel and let the bubbles come out. Did this many times on each front wheel until I saw no air bubbles coming out. The problem is there is no pressure on the front brakes unless I pump the lever about 10 times then the brakes work, I let go of the lever and again no pressure. I went back to bleed again, no air bubbles! No leaks that I can see on any of the lines. What did I miss? I am confused because all the parts are brand new OEM. Anyone have any ideas or tips? I’m stumped. I don’t think I have a clog in any of the lines or else I wouldn’t be getting fluid to come out the bleeder valve right?

You have bubbles trapped in the hose just beyond the master cylinder

Position the Mc so those bubbles can escape from that hose bend up thru the Mc. Jiggle the lever and you’ll see them bubbling up.
