What goes wrong?
The most common MOT failure reasons are significant brake effort recorded with no brake applied indicating a binding brake, steering head bearings excessively stiff, notchy, or with excessive wear or play and brake lining or pad worn below 1.0mm. The top issue, significant brake effort recorded with no brake applied indicating a binding brake, caused 15 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.
