What goes wrong?
The most common MOT failure reasons are significant brake effort recorded with no brake applied indicating a binding brake, the aim of a headlamp is not within limits laid down in the requirements and tyre tread depth not in accordance with the requirements. The top issue, significant brake effort recorded with no brake applied indicating a binding brake, caused 29 failures in 2024. Checking tread depth (1.6mm legal minimum, 3mm recommended) before your test can save an unnecessary fail. You can check prices at Black Circles if you need replacements.
