ABSTRACT:
A device for preventing the squeak in a disc brake apparatus in which friction pads comprised of a semi-metallic or a non-asbestos material are pushed onto a disc rotor to perform braking is characterized in that the disc rotor is circumferentially divided by the use of slits or couplings so that the frequency of second-order resonance in the longitudinal vibration of the rotor is higher than 15 kHz and thus inaudible to humans.
