These Rube Goldberg solutions are slaying me! We don't even know if the brakes get hot yet.
Do you drive in heavy city traffic, or up and down mountains? Is the vehicle heavily loaded or is it mostly just you inside? I'm a flatlander, mostly lightly loaded car, small towns and highway driving. I go over 100,000 miles on a set of brake pads. For me, the times the brakes get hottest are when the road salt causes corrosion such that the calipers don't release.
Other than that, I don't turn much gasoline into braking heat. If that is you too, then don't worry about it.
