Improved friction pads for use with disc brake. The pad has a central main portion and a peripheral portion which are formed of different matrices having different compositions. The matrix of the central main portion contains a hard substance or substances having a specified range of hardness whereas the matrix of the peripheral portion does not contain such hard substances or contains in only a limited smaller amount than the central main portion. This prevents the brake disc from wearing due to friction with the pad and thus avoids uneven abrasion of the brake disc.

Friction pad for use with disc brake

A brake disc and a wheel having circumferentially spaced mounting seats are secured by threaded studs to a radially extending flange of a hub to form a wheel assembly in which pressure-receiving portions of the wheel assembly are provided opposite the wheel mounting seats and a recess is provided between each pressure-receiving portion and a cylindrical portion of brake disc to permit deflection of pressure-receiving portions as hub nuts are tightened on the threaded studs.
