20080251326 | DISC BRAKE PADS HAVING A VISUAL WEAR INDICATOR WHICH SIGNALS THE NEED FOR PAD REPLACEMENT - A new method and apparatus signals to an inspector on a cursory exterior examination of a vehicle that brake pads have reached the limit of safe wear. Brake pads are designed to release a material that has a color other than the browns and grays of conventional brake pad dust when they reach the limit of safe wear. The colored material distributes itself on the wheel of the vehicle, thereby offering telltale evidence of worn-out brake pads. A first embodiment brake pad employs a colored powdered material enclosed in at least one pocket beneath the normal wear range of the friction lining. A third embodiment brake pad employs a heat-stable, colored liquid or slurry in metal capsule. The capsule is breached by rubbing against the brake rotor when the wear limit is reached.

This recess is filled with one or more layers of a brightly-colored visual indicator dye or dyes. As the friction material is worn sway by contact with the brake rotor, the thickness of the friction material is reduced until, eventually, the visual indicator becomes exposed at a predetermined depth. The visual indicator dye is pulverized and discharged onto the exterior surface of the wheel rim as colored brake dust. The presence of the colored brake dust alerts the driver of the need for brake pad replacement. | 04-02-2009 |
