What goes wrong?
The most common MOT failure reasons are a brake lining or pad worn below 1.5mm, the strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired and parking brake efficiency below minimum requirement. The top issue, a brake lining or pad worn below 1.5mm, caused 37 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. If you need repairs before retesting, sites like BookMyGarage let you compare local prices.
