Abstract
A pressure plate for a friction coupling such as a clutch or brake system includes one or more pockets with a phase change material disposed therein. The phase change material operates to absorb and release heat when the friction coupling cycles between activation and deactivation so as to minimize a maximum temperature of the pressure plate.
