Swm Silver MOT failure rate

What a Swm Silver fails its MOT on, and the part that fixes each.

What it fails on, and why

Other25.0% of failures

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

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.

Fuel system8.3% of failures

Fuel-system failures are leaks or an insecure filler cap.

Lamps & electrical8.3% of failures

Lighting is the single most common MOT failure and the cheapest to put right. A blown headlight, brake-light or number-plate bulb, a cracked lens, or a headlamp beam that points too high or low will all fail. Most are a two-minute bulb swap.

Steering8.3% of failures

Steering faults are typically worn track-rod ends or ball joints, play in the rack, or a split gaiter letting grease out and dirt in. Excessive free play at the wheel fails.

Registration plate8.3% of failures

A missing, damaged, dirty or incorrectly-spaced number plate, or one using the wrong font, will fail. A replacement plate is inexpensive.
