I replaced front brake pads on my Corolla at 75K, but they had some material left. Half of that driving was previous owner. Those pads are still on at 185K, and I just checked them, and at current wear they should be good until at least 220K. Find minimum thickness specification and measure them. It is also worth it to clean and lubricate them once in a while.
Rear shoes are original, but they are getting close to replacement. Probably about 220K as well.
