Q:What is the difference between organic pads and traditional pads?
A:With reference to your inquiry on the Wearever Silver Organic Brake Pads - Rear (4-Pad Set) - part# NAD 636, the best thing about metallic or semi-metallic brake pads is that they are cheap and durable. Because they are composed mainly of metal combinations, they will not wear down quickly, and are slow to become too hot from friction. Downsides to metallic brake pads include the loud squealing sound that drivers frequently complain about as brakes are applied. This results from brake pad vibrations as the metal of the pad grates against the metal of the brake rotor. The result of this violent meeting between equal materials is that the rotor can become grooved or worn over time, and will eventually need to be replaced when there isn't enough material left for repairs. Ceramic brake pads offer a much quieter and more reliable braking solution to drivers. This is because the materials in the ceramic mixture vibrate in a range outside that of normal human hearing, which gives the impression of a very quiet stop every time. In addition, ceramic brake pads do not become heated as quickly, and become cooler faster, which helps to eliminate brake fade over long downhill courses. The downside to ceramic pads is that they are much more expensive than their metallic counterparts. Some auto enthusiasts claim that this expense is offset by the lack of rotor damage caused by the pads, plus the time and hassle that is saved from having to occasionally replace rotors.
