Patent ID: 7905333

Claim:
An insulator adapted for placement between a brake pad and one of a piston and caliper of a disc brake system, the insulator comprising: a first metal layer having a first surface and a second surface opposite said first surface; a second metal layer having a first surface and a second surface opposite said first surface; a viscoelastic damping layer provided on said second surface of said first metal layer and said first surface of said second metal layer; and a friction enhancing coating provided on said first surface of said first metal layer and said second surface of said second metal layer and including; an epoxy based binder; and a plurality of particles contained and encased entirely within said epoxy based binder and having a minimum diameter of approximately 55 microns; wherein said friction enhancing coating is operable to increase the coefficient of friction of said first surface of said first metal layer and said second surface of said second metal layer.
