3 known faults with sources

Engines: 1.0 VVT-i (Petrol)

Applies if: Toyota USA tech tip for all its models: it applies if the judder began after wheels, pads or discs were removed or changed.

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

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.

Engine / equipment: Toyota Aygo X 1.0 built from 30/6/2022 to 22/8/2022
Period mentioned: 2022
Symptoms: You have to press the brake harder than normal: the brake servo assistance is reduced.
Possible cause described: According to ADAC, in January 2023 Toyota recalled 5,422 Aygo and Aygo X worldwide (868 in Germany) built from 30 June to 22 August 2022 because the brake servo assistance could be limited. The vacuum check valve (VCV) is replaced.
Check for the garage: Check by VIN with Toyota whether the campaign has been done. If the brake pedal is hard with the engine running, do not drive: call for assistance.
