Brakes are and interesting case. (I guess that you understand all of this, I only wanted to make the details more explicit.)
One important detail is that in brakes you convert the kinetic energy to electric energy directly. They didn't plug an electric generator to harvest the heat of and old disk brake.
Another detail is that the car has a lot of energy stored as kinetic energy, so you have a lot of energy to convert when you try to stop the car. (I'm too lazy to do the calculations now.)
I agree that harvesting energy from the deformation looks more promising that harvesting heat.
