Aaron Stergios, North Royalton, OH, 2001 dodge Ram 1500 4x4 5.2 L

My 2001 Ram 1500 4x4 has a pulsating brake pedal after I replaced some brake lines and installed new front pads and, rotors. I have bled master cylinder, prop. valve, and ABS valve. Truck only has rear ABS. I bled wheel cyl, and calipers. I have a good solid pedal but it pulsates up and down. Is there a special bleeding process or tool for this truck?
