Are worn brake discs an MoT failure?

My car passed an MoT in early June this year. Six weeks later a main dealership inspected it (as part of service) and told me the front 2 brake discs were both 90% worn. I probably did less than 200 miles in that six weeks. Should it have passed the MoT?

An MoT test should ensure that there is at least 1.5mm of pad material remaining in order to pass, so it is possible that you had this amount or more left on your brake pads, but if this was the case then we would have expected it to be shown as an advisory even if the vehicle was passed.

If you believe the car should have failed its MoT you can complain to the DVSA, but unfortunately this has to be made within 28 days of the test. However, you can still contact the DVSA to report the garage in question here:

I have a 64 reg Hyundai i10. On the last MoT in August last year there was an advisory which said that both rear brake discs were ' pitted or scored but not seriously weakened'. Mileage then was 24,000-plus...
If my car passed its MoT but has pitted and scored brake discs, is this supposed to be on my certificate as an advisory?
Is there a minimum brake disc requirement on Vauxhall Vivaro vans or is it an upsell?
