I recently had my brakes serviced. Pads and rotors were replaced. Everything seemed fine. Today, I took a 30 minute drive where I applied the brakes significantly on the way back due to hilly terrain, but nothing out of the ordinary.
When I stopped at home, I noticed that there was smoke coming from the driver side. What kind of brake problem would cause overheating only under conditions that required more braking than level terrain, but not braking that would usually be considered abusive? I've driven on those roads before with no overheating, before the brakes were serviced.
