Hi, HELP NEEDED. I have a 307 model and my question is how often should one change tires and the front brakes + disks? I was in the garage today and they have changed me the front brakes (I have 38000 kilometers only) Is that common ? I do not drive the car in some extreme way just the common driver :-) I spoke to one of mine friends and he told me that he had changed the brakes after 120000 kilometers!. THANK YOU !!!
