front end vibration solved!
HEY
I had an issue where when I hit the brakes, the front end of my truck would shake up and down violently. Two days ago I had a rear caliper give up its hold on a brake pad and come to find out that it was because a slider pin siezed up. So I took all the rotors and turned the good ones replacing the bad one as well as pads. After all I found that the pins in the passenger front caliper were stiff, the drivers front one was siezed but was extractable and the other was stiff. So after replacing 3 pins, a caliper saddle, caliper, all the pads, and a rotor as well as lubing all the pins all the shaking is GONE so to all of you that experience shaking during braking lube your caliper slider pins and let me know if it fixes your truck.

reasoning for pins
Having been a Machinist, I figure it was the pins causing it for this reason. when the calipers clamped the stuck or stiff pins would allow the pad to contact with uneven pressure and the pad would "skip" on the rotor being that my calipers are all two piston then it makes uneven pressure easy to happen. Its kind of like putting a piece of wood on a disk or belt sander and not getting it square on it, it will catch then release and continue to do so iuntil sufficient force is appled to force them to maintain contact which is what happened when I hammered the brakes, it wouldn't shudder.
