wl....K těm brzdám. Vnitřně ventilované brzdové kotouče s průměrem 390 mm vpředu a 356 mm vzadu, typu Porsche Surface Coated Brake (PSCB)
Vyhledal jsem info na Googlu a je to tak jak píšeš. PSCB brzdy jsou v základu železné brzdy, kde se Porsche vývojářům spolu s Bosch/Buderus podařilo do jejich povrchu "nastřelit" tungsten carbide částice.
Simply put, a brake disc made entirely of tungsten carbide would cost as much as several sets of ceramic brakes. Moreover, the technology wasn’t sufficiently advanced to bind tungsten carbide to a substrate—such as gray iron. But following a lengthy series of tests in close collaboration with Bosch/Buderus, Porsche made a breakthrough. A gray-iron disc was laser-processed to offer structure, then galvanized with an interlayer. The interlayer acts like a flexible bond to relieve the differential thermal extension of gray iron and tungsten carbide, which is then applied in a spectacular manner: a high-velocity oxy-fuel spraying process shoots tungsten carbide particles at the disc at supersonic speeds. For a moment, it looks like a Star Wars lightsaber is firing around the disc. The result is a coating around one hundred micrometers thick—but it still doesn’t do the trick on its own. Now what it needs are very special brake pads.
No a s destičkama měli zrovna tolik práce........zkrátka borci....čepici dolů.... :yes:
