What goes wrong?
The most common MOT failure reasons are a suspension pin, bush or joint excessively worn, parking brake efficiency below minimum requirement and parking brake efficiency less than 50% of the required value. The top issue, a suspension pin, bush or joint excessively worn, caused 84 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.
