Looks like a workshop in a complete mess to me!! As you live in Derbyshire, as do I, and went local you need to name and shame! I think I can guess as I have just bought my GS from a local dealer and was less than impressed with its presentation and had to make a complaint regarding the fact that the brakes had not even been checked prior to my collecting it. There was about 1 mm on the rear pads on a 4 month old bike, and all the calipers were dry and corroded inside. The bike had a 6000 mile service, allegedly, as well as a PDI inspection, and the wheels had been off for new tyres, so plenty of opportunity to spot the pad wear. I had a meeting with the general manager, amongst others, and they appeared genuinely horrified, but if this is the same place there's clearly a major problem and I will avoid them in future.
