Below is a list of Disc Brake Pads manufacturers from Cincinnati, Ohio. Disc brake pads are an essential part of many braking systems as they are the brake materials used to create enough friction to slow or stop motion. While used most commonly in vehicles, disc brake pads are also implemented in the braking mechanisms of locomotives, manufacturing machinery, and jumbo jets. There are three main components to disc brake pads: the pads themselves, the calipers and the rotors.
