Truck shakes severely when on the brakes
Your front brake rotors are warped. Remove them, see if they are turnable. (Metal brake lathe at auto repair shop, or auto machine shop)
The rotors have a minimum thickness. You cannot lathe them any thinner than this minimum thickness, or your safety will be at risk. (A reputable shop wouldn't even begin to ->Think about turning a rotor undersize. If they do this, and you are hurt, or killed, or someone else, they are liable!)
Your front brake rotors are like the shape of a thick disk, right? You have brake pads on both sides of this disk.
If the rotor is warped, you will have a thick edge on one side, and a thinner edge on the other side. (You're viewing the rotor from the edge)
As you apply your brakes the brake pads they squeeze against the rotor. They squeeze against the thinner edge, then suddenly the thick edge comes around.
This makes you brakes grab momentarily, then as the thin edge comes back around, the brakes let go.
Grab, let go, grab, let go. This is the teeth chattering stop effect, that occurs.
If the rotors can be turned, fine. If not, they will have to be replaced with new ones.
One more thing. As time goes by, this chattering effect when you are stopping, has put severe wear on your front end parts. You may have a bunch of front end parts that are badly worn. This is why it's imperative to have this problem fixed as soon as possible.
There is also the safety issue. What if you can't stop in time in an emergency situation? Either your life, and/or someone else's may be endangered.
