Had similar on mine a few year ago purchased those grooved and dimple brake discs but the feel on the foot was not correct nor was the brakes 100% and it pulled slighly to the left as though the wheels needed balancing . I asked a few mog owners and dealers had no luck. Then asked Dominic Mason his dad was Dave who raced the older lads will know of him.
Dominic told me the discs are made in China . I took the mog to him lives in the Lake district area and he stripped them down sent them away to have 1 or 2 Thou off each side of the discs, then refitted . His bill was not a lot now it can stop on its nose.
