Do a little preventative maintenance,take off the front wheel off once or twice a yearand check between your calipers to see how low your pads are,or if your at the dealer forv an oil change have them do a multi-point inspection which includes checking your brakes,it will save you money on having to replace not only the pads but roters also,and could prevent future injury to yourself and others by having them looked at and not waiting the last minute,hope it helps someone from headaches and aggravation.
