I had the car for a check at my service station prior to the trip. Sometimes there was a rattle behind my seat but I was not able to locate the problem. The last 300km the rattle was coming back more frequently. After crossing the Grossglockner street with a pass at 2500m I got no brake fading but suddenly one of the rear brakes blocked - happily directly next to a parking bay so I pulled in and got off the street traffic to wait for a tow truck. Everything would have been much more complicated earlier when I was still driving in Italy. That might have ruined my holidays but it happened nearly at home so only minor troubles.
