An issue with the brake servo will result in an MOT failure, furthermore it is dangerous to you, your passengers and other road users to have any fault with the brake system.

Quite simply as soon as you are aware there is an issue with it! These days it is rare that a brake servo will fail. As it is a sealed unit, water ingress and dirt will not enter it and cause any undue wear. However, it has been known for the sealed structure to fail due to corrosion on older vehicles.

The only thing you can do is ensure that the area where the brake booster is mounted is clear of debris and therefore water is not collecting in the area.

If you experience any untoward characteristics in your braking, or if you suspect there is any issue with the brake servo or there are concerns about its age or condition, book a diagnostic inspection immediately and do not drive the vehicle. Driving with a bad brake servo can impair brake performance and safety, and can be lethal.
