Not really NORMAL Harry.---On a vehicle not used often the disc can start to rust. This can make a part of the disc abrasive and will wear the pad material away and the rust will not polish off. As less of the surface of the pad is in contact the pressure gets higher and higher eventually removing the rust. You are then left with only a fraction of the disc providing any stopping power. The MOT station was remiss in giving the braking system a pass.--A visual inspection should be used and not just the dial on the brake tester.
Also the pads will wear faster due to the excessive pressure. Altogether not a good thing. ( Can even lead to brake failure due to over heating when descending a long steep hill for instance. )----
