Factory original brake pads are made of metallic compounds featuring a large percentage of steel wool. As they grip steel rotors to create the friction that allows your vehicle to stop, abrasive wear is significant. Rotors wear down faster and the metal scraping from steel fibers can cause loud squealing that varies with temperature variations and weather conditions. When driven hard, metallic brake pads can generate excess heat buildup to cause the formation of grip-reducing hot spots on brake rotors. Many automakers that develop high performance models capable of high speeds will attempt to offset these disadvantages by reducing the metal content in brake pads, creating a softer material that grips better at fast speeds with less noise. However, these soft brake pads wear out faster and produce large amounts of visible black dust that soils aluminum wheels and ultimately becomes corrosive to finishes applied on them.
PowerStop offers a solution to the woes of underperforming factory brake parts with the 1-Click Brake Kit. It features brake pads made of ceramic compounds instead of traditional metallic ones, and comes complete with rotors that are cross-drilled and grooved for superior heat disbursement. Used in street performance where 200 mile-per-hour speeds quickly generate blistering heat, ceramic brake pads offer the natural ability to stay cool under the most severe conditions. When ceramic brake pads are combined with perforated rotors, heat buildup is reduced so extensively that brake fade rarely occurs due to fluid reaching boiling temperature. Ceramic brake pads are far quieter due to their higher resonant frequency undetectable by human ears, so squealing is not an issue. And finally, ceramic compounds last longer and produce finer, less obtrusive dust that does not stick to most wheel surfaces.
While the many advantages of ceramic brake pads and cross-drilled brake rotors typically come at a high cost, we offer you the superior all-around performance of these parts with value-priced kits from PowerStop, a leading high-volume manufacturer of brake components since the 1990s. You don't need a high-performance vehicle to enjoy the benefits these brake kits offer, and you might find your dealer charging a similar price while giving you less. We invite you contact our knowledgeable specialists seven days a week for help with any questions you have on PowerStop brake parts.
