I had a bit of spare time today so I popped out to the garage at home and fitted the new rear pads to my bike. I think the tester was just being picky - there was at least another couple of hundred yards on those pads…..It failed on the rear brake pads being just down to the metal. I realised that when they put it on the brake tester - performance was fine but I could just hear it as the engine wasn’t running and I wasn’t wearing a helmet at the time.
