Okay so I just put my Rancher back together this past weekend and I have it running and driving perfectly. But now my front brakes don’t work. I have triple checked to make sure fluid isn’t leaking from the lines and all the banjo bolts are tight and have copper washers. I have spent a total of 3 hours bleeding them constantly and have used about 20 ounces of brake fluid through the system. The brakes will not build any pressure at the handle until about 8 quick tugs on it. Slow pomping doesn’t do any good to build pressure at all. When the brakes do pressurize after 8-10 pumps and have full pressure all the way through the handle, I crack the bleeder on either wheel and nothing but fluid comes out. There is no longer air and the fluid is shooting out. When the brakes are pressurized, one whee has enough braking force to lock up while the other has next to no brakes behind it.
I wrecked this bike last year and after I reassembled the brakes I bled them enough to wher they had full pressure after two quick tugs on the handle. Since draining that fluid out and trying to bleed them again they have gotten even worse.
What could be the cause of this?

Please no one hesitate to throw in ideas. I use this ATV at the local dirt track to move broken cars and need it fixed by Saturday
