Title: Partial lining disc brake - has pad retaining leaf spring containing turned up resilient tongues reaching into cavities above the lining
Inventor: CASPER EDUARD
IPC: F16D55/00
Filed: 1973-09-11
Abstract: The primary requirement of the lining retaining arrangement is to prevent any radial movement and allow only axial movement against the disc surface during braking operation. A leaf spring retaining the pad against the brake holder is part of the arrangement. Prior designs provided this leaf spring in such a way that a rather loose fitting of the spring between the brake holder and brake tongues resulted. The provisions of the present design achieve a positive hold of the spring which now can be inserted into the brake holder before the fitting of the brake and the turned up part of the leaf spring provide a positive resilient meshing between the leaf spring and yoke.
