Brake pads wearing thin

Last reviewed 22 October 2026. General information, not advice about a particular car.

Fix soon Will get worse and may fail the next MOT. Budget for it in the next few months.

Brake pads are consumable; this one is near the end of its life. Replace soon or they will score the discs and the job gets more expensive. Below 1.5 mm it is a fail.

What the wording on the certificate means

You’ll usually see something like “Brake pad(s) wearing thin”, often with a position such as “nearside front” (the passenger side) and a reference to the MOT inspection manual in brackets.

The friction material on the brake pads is getting low. Pads are designed to wear and are replaced routinely, usually in a set of four on one axle.

Why it matters

Once the friction material is gone, the metal backing plate grinds against the brake disc. That damages the discs, makes a grinding noise and reduces braking.

What to do

Will it fail the next MOT?

An advisory isn’t a fail, and the car can be driven, as long as it stays roadworthy. Pads less than 1.5 mm thick are a major defect and a fail.

If you’re buying a car with this advisory

Thin pads aren’t a reason to walk away, but they are a cost to factor in. If the same advisory shows up at test after test, it has probably been left unrepaired.
