Even though my car hasn't spent that much time outside, the sticker on the brake bias knob faded and cracked. If anyone else has the same issue, you can order a replacement sticker here. I ordered both the "front" and "rear" stickers since I couldn't tell which one I needed. The "front" sticker is the correct one.
