With One of the inherent properties of Ceramicool™ is its refined ability to dampen the harsh noises associated with the engagement of semi-metallic pads withthe hard metal surface of the rotor.  The Ceramicool™ organic friction formulation eliminates brake groan and creep noise associated with semi-metallic formulations.  Also available are TruQuiet TruFit™ noise suppressing shims that can further enhance the benefits of OE style slots and chamfers which are standard on all Ceramicool™ brake pads.
