Abstract
Expanded graphite and/or vermiculite are introduced into the friction lining mixture to eliminate or substantially reduce the amount of binder present therein. The friction lining at most contains from 2.5% by weight of binder. By omitting/reducing binder, the production is very stable and the friction linings can be easily reproduced. The process steps of hardening (including the hardening furnace) and scorching (including the necessary equipment) can be omitted when making such friction linings.
