Brake issue?

1st Sorry I realized this morning I posted this topic in the wrong section, so I am copying it here, which should be the proper section, it was late when I originally posted it and I guess I did not pay attention. Anyway

Issue!
Guys we just installed new calipers, rotors and pads on the front of my stock set up 93GT. We replaced because it was pulsating and when we took it apart the pass front rotor showed some hot spots on it, so our tech recommended to replace the calipers, I figured what the hell they were original to the car and have 100k on them, so replaced they got.

Now I have an issue that I can't remember if I had before. If you are at a slight roll and jab the brakes the pass front wheel assembly will jolt, enough to where if you walk beside the car you can see it and can feel it in the car. Pulsation is back, just not as bad as it was with the old rotors. This brake job was done 2 weeks ago.

So at 1st we pulled the rotor back off, and put it on the lathe and it was warped, no biggie, machined it and back on the car. Jolt still there and pulse seems like it never really went away. You can feel that it is coming from the pass front. So I have ordered another set of calipers and new front hoses to put on. Our supplier will take the others back.

Now another thought we were discussing today is. Could this be a strut issue? Like maybe a bad strut mount? Allowing the force of the brakes and the motion of the car allowing to it move some??? With the old calipers it did not pull when braking, just pulsated.

Thanks

Rotors are the better Ray Bestos rotors, ordered from CJ and the pads were Wagners and the calipers were A1 cardones?

Oh yea the front end parts look good and tight? Still OE but look ok.

Did that with the ball joints the other day on the front end rack. If it indeed is in the brakes, then why would it make the wheel itself jump ? That's what is confusing.
