What to check before the MOT

Built from this model's own failure record, not general advice.

Start with the less effective brake control does not achieve an efficiency of 25% - it accounts for 35.7% of failed tests on this model.
Then check missing and too low, the next two most common reasons.
The most common advisory is tread depth is below minimum requirements of 1.0mm (4.4% of all tests) - not a failure, but money you will spend sooner or later.
Average recorded mileage at test is 5,988 miles, which is the number to compare any advert against.
