As cars get faster and heavier, capable brakes are arguably more important than ever. Even with the assistance of regenerative braking from electric motors, brakes need to be able to handle some incredible stresses nowadays. Also, as capable as modern brakes are, they do have limits. In some extreme cases, such as going downhill or slowing from extreme speeds, heat becomes a problem that can lead to reduced performance and even damaged brake components. A recently granted patent from Tesla aims to change that, but maybe not in the way you’d hope.
