What materials are used for brake pads?
1 Answers
Brake pad materials: Asbestos-type brake pads. Below is relevant information: 1. Semi-metallic friction materials: Used in disc brake pads for passenger cars and heavy-duty vehicles. Their material composition typically contains 30% to 50% ferrous metal content (such as steel fibers, reduced iron powder, and foamed iron powder). 2. NAO friction materials: Broadly refers to non-asbestos, non-steel fiber friction materials, though current disc pads may contain small amounts of steel fibers. The base materials in NAO friction materials are most often mixtures of two or more types of fibers.
