Shark Industries' Ceramlub Extreme Temperature Anti-Squeak Brake Lubricant ensures quieter brake performance. In fact, it eliminates brake squeal associated with 3/4-ton trucks when used on economy brake rotor pads. Brake noise comebacks are never an issue through the entire life of the pad thanks to the proprietary high solids ceramic formula. It holds up to demanding conditions and is approved by the biggest OEM brake parts manufacturers.'
