My 93 gs300 has a severe vibration under light braking. Allready replaced the front brake rotors,pads,shims, lower ball joints all with factory parts. I am at a loss. No Abs light is on.

 

Check lower front control arm bushings, it's a two piece arm so besure to check both front and back bushings, it's usually the strut rod bushings that go bad. (caster arm bushing)

 

The new rotors could also be warped.

 

Thanks for the replies. I measured rotor runout .002 or less, isn't that ok? Wouldn't I feel vibration through the steering wheel if control arm bushings were bad. I don't feel it in the steering wheel, I feel in the car. the shifter even shakes!

 

The rear rotors could be the culprit or maybe you have a stuck caliper that is not releasing all the way. I had this problem years ago and it was due to rear rotors.
