Abstract
An abrasion evaluation test method is applicable to a case where a rotating disk and a friction member to be brought into sliding contact with the disk contact and abrade each other even while a brake is not applied due to vibrations and mounting errors. The disk is an actual disk, and the friction member is a test piece which is smaller than the actual friction member. The test piece is pressed against a frictional surface of the disk at a predetermined position, thereof. The abrasion of the disk is measured with respect to a portion of the frictional surface that is out of contact with the test piece, while the abrasion of the friction member is obtained from the difference in thickness of the test piece before and after testing.
