What a Triumph T140b fails its MOT on, and the part that fixes each.

What it fails on, and why

Brakes16.7% of failures

Brake failures cover worn pads and discs, an imbalance between wheels, corroded or scored discs, or a binding caliper. Braking efficiency is measured on a rolling road, so a spongy or pulling brake shows up as a low reading.

Visibility/wipers16.7% of failures

Visibility failures include torn or smearing wiper blades, a washer jet that does not reach the screen, and chips or cracks in the driver's swept area. Blades and washer fluid are quick, cheap fixes.

Other16.7% of failures

This covers a range of smaller items, from a non-working horn to a warning light left on.
