Don't go halfway when it's time to redo the brakes on your truck. Whether you tow a trailer, race or just drive aggressively , you should have the best brakes possible. Power Stop gives you the best of both worlds: let's start with the brake pads. Factory, OEM brake pads are a bucketful of compromises. They balance several factors, including pad noise, dust generation, service life, cost and – oh yeah, friction. But what works for most can be improved on. These Z36 metallic pads have a 17% higher coefficient of friction than OEM pads, giving you more stopping power, without standing on the pedal at the bottom of every long hill.
That would make these pads a great upgrade on your stock rotors, but you've already decided not to go halfway. Don't try to reuse your old discs, even if they still have enough meat on them after refinishing them to meet minimum thickness specifications. A thinner disc is a disc that has less mass. And it takes lots of mass to dissipate heat in a hurry, so get a pair of Power Stop drilled, slotted discs at the same time. Mass soaks up heat quickly during a panic stop, but it takes surface area and moving air to keep the rotors cool on a long downhill or in heavy stop-and-go traffic. Cross-drilling a disc adds surface area for improved cooling, but it also makes a dramatic improvement in braking performance in the rain. Cross drilling keeps water from wedging between the pad and disc surface, making the pad hydroplane, which severely affects braking ability.
Slotting does help some in the rain, although it has other advantages. During a high-speed stop, especially with a trailer or heavy load, the organic binders in the pad material will literally boil. This is normal; the problem is that the outgassing binder turns the pad into a hot little air-hockey puck that barely touches the disc surface. It rides on a pocket of outgassing binder, keeping the pad from contacting a normal, unslotted disc. Slots sweep the gases away, letting you glide to a normal stop in time instead of running that red light at the bottom of the hill with both feet standing on the brake pedal. Not fun. Power Stop's 1-Click Extreme Truck and Tow Brake Kit combines the advantages of both cross drilling and slotting to provide you with superior stopping ability, whether it's halfway down a hill, while towing, or during the rain. Add in the superior grip, low noise and dust generation of the Z36 high-friction metallic pads, and stop in comfort and safety.
Power Stop also uses the best technology for anti-squeal shims: constrained steel. A sandwich of two layers of steel with a viscoelastic layer between them prevents acoustic coupling between the pad and caliper piston, eliminating brake squeal. Other manufacturers attempt to use a single layer of steel or a layer of Teflon to achieve this. Power Stop's solution, while pricier, is far more effective.
Founded in 1997 in Southern California, Power Stop® began with the goal of bringing the benefits of superior brake components at a reasonable cost to street performance and backyard performance enthusiasts everywhere. Company management and engineers believed then, as they do today, that better brakes make driving more enjoyable and safer for any vehicle, terrain, and driving style – not just street performance. They developed a philosophy that while brake components cannot be superior without the most advanced materials, they also cannot perform in a superior fashion without matching the exact tolerances of each and every individual vehicle they are created for. Relentless development and testing led to brake pads, rotors, drum shoes, and other related components that delivered uncompromising fit and operation, and Power Stop’s customer base grew exponentially from positive word of mouth. The company still has its original passion for creating the best products at the best possible prices, so when it comes to replacement brake components for your vehicle, Power Stop is the only name you need to know.
