While most pads are formed from fibers and organic materials bonded together by resins, CL Brakes Sintered Pads begin as powdered metals such as iron, bronze, and copper, mixed with roughly ten other constituent materials including graphite and carbon. The mix is compressed in a tool under extreme pressure to give it shape, and then brazed onto a backing plate in an oven at 1800F. The resulting material is characterized by a consistently high coefficient of friction, stability at high temperatures, and an extremely low wear rates.
CL Brakes originally created sintered brake materials for military applications such as tanks, helicopters, and airplanes, as well as high speed freight and passenger trains like France's TGV. After extensive development, the technology was successfully introduced in motorcycle applications. The most recent development has focused on aligning the sintered technology with racecars. CL Brakes have now been used successfully at the highest levels of motorsport, including World Rally Championship (WRC) and NASCAR Sprint Cup.
The first thing you’ll notice about them is the incredibly high, yet controllable bite. You’ll likely use less pedal pressure than you’re accustomed to, which means no more standing on your brake pedal praying for the car to stop while diving into turns. You’ll also have incredible cold bite, which is of great value to autoX and Time Attack participants, who typically have little or no time to warm up their brakes prior to timed runs. Regardless of your engine package, tires, or the track you’re driving, it’s highly unlikely that you’ll ever fade the RC6 compound. Since the material is so dense, the RC6 feels rock-hard underfoot. The RC6 has become a bread and butter pad among rally drivers in Europe due to its relentless bite in every imaginable track and weather condition. Most experienced drivers have a ‘wow’ moment the first time they drive the RC6, as they’ve never felt anything quite like it before. The RC6 is typically used on the front of most cars, although it’s a great rear pad option if RC8 is being used on the front.
