Brake ling
A brake lining is a friction material bonded to the steel brake shoes or pads. In most automotive brake pads and shoes, the brake lining is riveted to the metal pad or shoe. As the brake lining wears down, the brakes may chatter, squeak or squeal. Left unattended, the brake lining will continue to wear until the rivets begin to eat into the rotor or drum and generate the need for a costly brake repair. Brake pads and shoes are typically replaced as a unit, unlike earlier brake jobs that required a new lining be applied to a vehicle's brake pads.
When deciding on new brake components for a vehicle, there are often many choices for the type of brake lining used. As a rule, the lining that includes a lifetime warranty is a very hard friction material. This material is intended to wear for a long time, requiring less frequent brake changes. The downside is that this very abrasive substance is prone to wearing out brake rotors and brake shoes at a much faster rate than the original type brakes. When choosing a lifetime brake pad, it is wise to reference the vehicle manufacturer's recommendation.
