Squealing brakes are usually caused by the metal back of the brake pad vibrating against the caliper piston. Disc Brake Quiet is a paste or spray applied directly to the back of the pad. It dries to form a rubbery, dampening layer. This dampening acts as a cushion, absorbing the high-frequency vibration before it turns into noise. Let the compound dry until it is tacky before installing the pads. Never get this compound on the friction material or brake rotors.

Frequently Asked Questions
Apply a thin, even coat only on the metal backing plate of the brake pad where it makes contact with the caliper piston or caliper frame.
The paste usually takes 10 to 20 minutes to dry to a tacky state, depending on temperature and humidity. Do not install the pads wet.
High-temperature brake grease can be used on slide points, but Disc Brake Quiet forms a solid bond that stays in place longer under direct piston contact.
