Abstract

A brake or a clutch for motor vehicles having a first component (10) and a second component (16, 18), that can be moved relative to each other. The first component (10) has a contact surface of a low cost aluminum or aluminum alloy. The second component contains a support component (16) to which a friction lining (18) is applied which can be pressed against the contact surface. For a cost effective configuration that makes it possible to absorb high levels of brake energy with high durability together with a very good heat transfer from the friction contact zone, it is proposed that the friction lining (18) be of an organic material of predominately carbon compounds, in particular of paper. Furthermore it is advantageous that the first or the second component (10) rotate at least partially in a lubricant.
