Sil-Glyde Brake Lubricant is a silicone-based brake lubricant recommended for the entire brake assembly, is compatible with plastic and rubber (EPDM & Nitrile), and dampens vibrations between contact points. It is moisture-proof and heat resistant to over 425 degrees F (218 degrees C), which means it won't burn-off like other brake noise products. Its long-lasting properties provide a noise-free brake installation and easy disassembly. Using AGS brake lubricant is one of the keys to eliminating disc brake squeal and protecting parts from corrosion and rust.
