Brake Lining
Brake lining is heat-resistant material that presses against the brake disc to create friction. Friction materials, like those used in brake lining, are used to increase friction in applications when a decrease in movement is desired, such as in braking mechanisms. Brake systems use friction materials to stop wheels from rotating. When a brake is pressed, it activates a system that places the friction material against a disc that slows the wheels of the vehicle.
Brake lining is often referred to as a brake pad. The lining must be capable of enduring the high temperatures created by friction forces. Although asbestos was most often used in the past, brake lining is now usually constructed from ceramic materials. Most all vehicles use brakes, including automobiles, trains, motorcycles, and bicycles.
Brake lining needs to be replaced periodically. When brake lining is worn out and ready to be replaced, a warning sound is emitted when the vehicle is braking. This sound is usually an unpleasant high-pitched squeal. If this noise is ignored for too long, braking components can be damaged.
