Yes, well... I had extreme warped rotors on a Trooper with no vibrations at all, but alotta noise when I braked.
A true test would be to set up a dial gauge and check for run-out I guess.
If they are true,uhmmm, check all related front end parts, My 87 300E had a terrible groaning noise when I applied the brakes and turned left, it was the lower ball joint.
