Title: Brake pad with titanium covering layer - is used with narrow gap for ensuring rapid braking response
Inventor: SCHMITZ RUDOLF WERNER
IPC: F16D65/06
Filed: 1977-01-04
Abstract: The brake pads made from titanium are used in ground vehicles of all kinds, track laying military and commercial vehicles and aircraft.
