Brake linings have held up fairly well on the EPICA, however on cars with rear disk brakes, the rear pads typically don't last real long. Probably a good idea to have them checked given the current mileage on the original set. As was mentioned, have them checked when you have your tires rotated most places that sell tires offer free tire rotations, but may charge to check brakes. You bring the car in for a rotation they shouldn't charge you to check the brakes at the same time.
