I replaced my front brakes at 50K miles and my rear at 60K miles. I placed ceramic pads. This was a very easy job. If you have a bit of time and knowledge, it will save a lot of money to DIY. There is so much improvement in driving with this style of pad. In addition, when I did have the standard on the rear and ceramic on the front, there was a marked difference in the temperature of the wheel after driving on the expressway. (lower temp, lower wear on the tires)
