Longlife Friction Couples

Abstract

The advanced alternative powertrains regarding their electrification bring as a consequence a large levels of recuperation implying a small intervention of the hydraulic system during the brake lifetime.This new scenario for the brake system could have and important impact in the brake design regarding properties such as mu stability, corrosion/stiction, NVH… and the test design for their development. Moreover, the aftermarket for friction material and brake rotors is an important industry with significant commercial impact for all levels of the supply chain. How far is this trend also justified in technical terms? How should be designed the new brake systems and tested the new brake systems? Which is their environmental impact? Which are the main technical challenges regarding the longlife brake pad material, rotors, shims, backplates and calipers?New test need to be developed and harmonized?
