How to avoid failing your MOT on brakes

MOT Advice

Brakes are one of the most used part of any vehicle so it is no surprise they are on of the main reasons so many vehicles fail their MOT. If neglected they could not only become dangerous, but could also lead to other more costly repairs. This is why during any MOT, the brake pads, discs and in some cases shoes, will be checked.

Wearing thin

A technician may notice your brake pads are wearing thin, but considers it is still safe to drive for a set amount of miles. In this case they will add an Advisory note to your MOT so that you have a record that the brake pads will need replacing at a later date.

If your brake pads become so thin (less than 1.5mm) they will need to be replaced immediately otherwise it will impede your ability to stop when you need to.

Weakened disc

If the lining of your brake pads is left neglected it will cause damage to the brake discs. The metal from the pads will score the metal on the discs, which will cause them to become weak, and in need for replacement.


If your brakes are juddering when applied there could be a number of reasons including:

  • Warped discs – caused by leaving your foot on the brake in traffic as opposed to applying the handbrake
  • Residue left on the brakes – caused by hard stopping and then holding your foot on the brake as the car cools
  • Leaving your car parked in the cold for a few weeks while you go on holiday
  • Uneven pressure of the brake pads on the discs

If you are experiencing a juddering when you brake it is important to get this looked at by a vehicle technician who can professionally diagnose and fix the problem for you.
