Official summary
TSB: Some 2011 ? 2014 model year Sienna vehicles may exhibit a vibration/pulsation from the front brakes that can be felt in the brake pedal while lightly applying the brake pedal. New front brake pads and a new field fix repair procedure have been developed to improve this condition.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
