Quite interesting, Just had 3000k service and I mentioned to the service guy that the brakes seemed to shudderd very slightly. It seemed to me that they are aware of the problem so they promptly machined the disc's - normal there would be questions like at what speed does the shudder accure at / or is it under hard braking or normal braking, but no questions at all. My main concern was QC as the XR6T was delivered with a crease on the bonet, paint chips, rear door that doesn't close properly, doors not lined up evenly and rear parcel self not inserted correctly. talk about pre - delivery $900 what for. My driving is mainly city with little highway use other than that - what an awesome machine
