Not doing much driving myself, my front discs on my daily are suspect for MOT. I'm driving the car now & then & some exuberant braking applied to keep the discs clean. Personally I think they would pass but a tester may have other ideas. Decided to have a look for discs & pads just in case & purchased Ferodo . Discs are coated. Best price I could find, apart from the cheapo Chinese stuff.
