Super Lube® Silicone Brake Grease is designed for caliper and wheel cylinder assembly work because silicone is an excellent lubricant for rubber and plastic. It is compatible with all rubber compounds including nitrile, Teflon, nylon and other synthetic rubbers.
Brake Grease should be used at every point in the brake system where parts slide or move. With disc brakes, lubrication points include the caliper slides, pins and bushings, the contact points where the pads slide within the caliper housing, self-adjuster mechanisms on rear disc brakes with locking calipers, and the parking brake cables and linkage.
Brake Grease can also be used to dampen vibrations between disc brake pads and caliper pistons. But it should not be applied between the pads and any noise suppression shims that may be used. Use it on the back of a bare pad or between the pad shim and caliper, and use it sparingly.
