Default Re: rotors

If when slowing down while braking they would definately be warped. What model XR. If pre AU could also be wheel bearing adjustment.

If there's vibration at high speed without touching the brake pedal, the cause is wheel balance.

If there's viration ONLY when you touch the brake pedal, it's the rotors.

Agreed. That's the most likely cause.

If getting the wheels balanced doesn't get it sorted, perhaps one of the calipers is sticking. That'd be pretty rare though.

Severely warped rotors will vibrate a bit with no brake pedal applied at high speeds, If you hit the brakes and it shakes a bit more its definitely rotors.

Default Re: rotors

another place to check,
the front lower control arm bushes
once they are old they can perish/fatigue and sort of go soft too,
when you brake they can move around a lot and cause vibrations
