Page 5 AERONAL CAST IRON FLOATING DISCS 1-CAST IRON : THE BEST MATERIAL FOR BRAKING DISCS Universally used in car races (F3000, GT, Rallyes) and by all the "highperformance" disc manufacturers, the cast iron allows a faster dissipation of the heat than the steel and stainless used for the original discs of the bikes (because of the lower cost). It is also better heat-resistant. BERINGER has developped a gray cast iron alloy and heat treatments that assure a total reliability of the discs even in very hard conditions. The cast iron rotors are covered with anticorrosion "aluminium plasma". 2- A 20% SAVING OF WEIGHT : The disc can reach much higher temperatures and can be used with sintered metal pads, thanks to narrow braking surfaces without holes, associated to new heat treatment The hub has been manufactured out of a highly performant aluminium alloy, used in the aeronautics. 3- LESS CONSTRAINTS : Thanks to an exclusive system binding the hub and the braking surface with setting over the supporting areas, the constraint at this very place is devided by two, and the working life of the disc increases. 3- GAIN OF MANOEUVRABILITY : The gyroscopic inertia is appreciably reduced by the use of narrow braking surfaces and 6 studs instead of 12, upgrading the manoeuvrability of the bike. 0 50 100 150 200 250 300 DISC TEMPERATURE BERINGER CAST IRON STAINLESS STEEL The aluminium alloy brake hub is machined from the solid is given a surface anodizing treatment, and is in contact with the 12 studs in special low-friction steel The initial play in the floating disc (necessary for best performance), remains constant throughout its working life and even beyond. These discs have drilled braking surface for road or sport use. In fact the holes drilling allows the use of organic pads (or sintered metal pads). For a race use in competition on circuit, it is highly recommend to use the AERONAL disc (see following page) Classic discs on Harley Bike CLASSIC DISCS
