Being the new owner of a 2014 Corolla S, I wonder what is recommended in terms of preventive maintenance for the rear brakes with discs? Just asking because I had a 2013 Kia Rio and they recommended to remove pads and calipers twice a year to clean them and lubricate the sliding pins, if necessary. Even thought, I was doing the recommended procedure, I still had trouble with those brakes. In the end, this Kia ended up causing so much trouble that I decided to buy the Corolla. I had to replace rear discs and pads twice in the last two years. Also, the paint was flaking off in many places.
