Abstract
Granules for a friction material is produced by: granulating a mixture including a friction modifying granular material and a resin binder in a fluidized bed under a presence of a liquid including a water-soluble or water-dispersible binder. The granules have a particle size of from 100 to 2000 μm, an angle of repose of 40° or less, and a compression breakage strength of 10 MPa or less. The friction material is obtained by using the granules.
