Sometimes you can chase your tail around and not get anywhere... If you feel that you can build enough braking power to safely drive the vehicle, go hit the road. Until the brake pads bed in to the rotors, brakes can act "soft" (goes with almost any brake job even on a dead stock "what ever" kind of vehicle). Jack up your rear end SAFELY up off the ground, and see if you can achieve enough braking to overcome some engine torque applied to the spinning wheels. If you can stop the wheels from turning, even with some mild throttle applied, then you should have enough braking power to safely take the vehicle out on the road.
Look up "bedding in brake pads" on the internet, then go essentially do it.
I'll bet you find the brakes improve rather quickly. Do note that re-bleeding the brakes afterwards will also likely still gurgle up some air out of the brake system. You may also find some useful info here:
