You may want to exchange/replace/flush your brake fluid. It goes bad over time and should be replaced every 24 months. I bought a 2013 this year with 4k miles on it and the fluid was about black. Still worked, but not good for the overall brake system. Super easy to do with a liter of brake fluid, hand vacuum pump, and a little patience. You will be glad you did when you least expect it (daily for me while commuting).
