Questions that narrow it down
General checks. Answering them does not confirm the failed part on this vehicle.
Worth checking first
- Confirm the vibration occurs during braking before treating rotors as the only part.
- Pads and calipers can contribute; inspect them rather than replacing rotors in isolation by default.
Safety
When not to keep driving
- If the pedal sinks, stopping distance feels much longer, or the vehicle will not stay in a straight line under braking, do not keep driving at speed. Have the brakes inspected.
