Abstract
An asbestos-free disc brake pad is provided by employing a cyanate ester-based resin composition as binder. The disc brake pad exhibits consistent braking properties over a wide range of operating temperatures and an improved service life. Also the serious pollution problem due to use of asbestos in the conventional brake pads is removed.
