I noticed recently my brakes at starting to screech. Was planning on doing them this weekend so I looked at them yesterday and noticed both front and rear r-s brake pads are worn and both front/rear l-s brakes still have quite a bit more life. Why are my r-s brakes wearing out before the left? Is this normal or should I take it to the dealer to look at? To me it doesn't seem like normal wear I'm thinking something is wrong causing one side to wear out faster than the other. Any input? Advice? Is this something the dealer will cover under warranty?
