Sounds like bad rotors again. Also check to make sure your calipers are not sticking.

Moderator reinforcement: I totally agree with Tim-to prove it: Mike it or use a dial gauge and check for out of roundness and the parallelism of the rotor-Caliper piston might not be retracting due to its seal or its binding inside the bore.

Where do you feel the shake? In the seat or the wheel? If fronts are warped you will feel the pedal bounce and maybe the steering wheel shake, if you feel the truck shaking and it seems to come from the seat area, check the rears, get the truck up to speed and use the parking brake, feel anything? Before you do this get under it and pull on the cables to make sure they work, then as you do the test keep the release lever pulled, or if it's a locking pedal apply the pressure so it releases as you do it! Start with light pressure and continue the force unless you can feel it right away.

As soon as the brakes are applied the shaking starts and gets worse the harder you brake. The shaking is the whole front end but it doesnt pull to either direction it is like it is loping. This all started after replacing ball joints.

You need new rotors is my opinion.
