Brake judder from wheel nuts over-tightened or tightened unevenly (Toyota tech tip)

Engine / equipment

Any Toyota: it depends on how the wheels are tightened

Period mentioned

2016 tech tip for all its models

Symptoms

Vibration in the steering wheel and the pedal when braking, even gently and at any speed, often shortly after wheels, pads or discs were changed.

Possible cause described

Toyota points out in a tech tip that if the wheel nuts are over-tightened or tightened unevenly (a single one is enough), the brake disc is left with runout and brake judder appears. It happens above all when they are run fully home with an impact gun instead of a torque wrench in a star pattern.

Check for the garage

Ask the garage to loosen and re-tighten the nuts with a torque wrench, to the manual's torque and in a star pattern, and to measure whether the discs have been left warped; if so, they will need skimming or replacing.
