But being a thermal engineer (retired), I question the "hole in the brake pad holder" idea. If the holder's made of aluminum, it's going to be an excellent conductor of heat. More aluminum in contact with brake pad material is a good thing. Conduction pad-to-aluminum-to-air is going to be quite efficient.
Interesting. I wonder if any engineers were involved in then pad holders w/ holes design.
