Audi R8 4.2/ R8 5.2 365x34 2-Piece Front Discs by Brembo (Excluding Ceramic Brake) (101.9007A )

  This system consists of 2-piece disc assemblies which directly replace the OEM discs.  About Brembo 2-Piece Discs Brembo 2-piece discs are made up of an advanced cast-iron alloy which offers an exceptional coefficient of friction and resistance to thermal shock and fatigue. As the braking system's primary function is to dissipate heat, larger, more sophisticated discs are used in order to increase the fade resistance of the system. These discs are directionally vented for enhanced cooling, as well as drilled or slotted for improved consistency, continuously cleaning and refreshing the pad surface.   2-Piece Discs   Through Brembo's comprehensive understanding of materials and advanced design capabilities, Brembo's 2-piece discs are designed to be as lightweight as possible without compromising strength or longevity. Achieving this level of design is a capability that sets Brembo apart. By manufacturing the center section out of precision milled billet aluminum, a great deal of weight can be saved in this key location. This reduces both unsprung and rotating weight which benefits handling, acceleration overall vehicle dynamics. Superior metallurgy and exceptional engineering allow Brembo discs to exceed in the most demanding conditions. Their advanced cast iron alloy lasts longer than any disc in the high performance and racing market.  Brembo's properitary floating hardware system permits a specific amount of radial and axial float which allows the disc to grow independent from the bell, averting thermal distortion when subjected to extreme temperatures. It also preloads the disc assembly to prevent premature wear and eliminate noise during street use. Brake systems are designed to operate best within a prescribed temperature range. While modern high performance friction materials broaden this temperature range, it is critical that the brake disc in a system has adequate thermal capacity.    Thermal capacity, or heat storage capacity, is determined by how much weight or mass is located in the outer ring section of the disc. This is the area where the friction surface of the disc meets the internal vanes. The more mass located in this area, the more thermal capacity a disc has.    CROSS DRILLED Cross drilled discs run at slightly lower temperatures due to added air flow through the surface of the disc where heat is generated. They are also highly effective in wet conditions and shedding debris from the disc to ensure a clean braking surface. Improve pad “bite”, improve wet weather performance, continuously refresh the brake pad SLOTTED DISCS Slotted discs are recommended when using race pad materials or compounds. the vehicle is submitted to extreme braking duties such as towing or hauling heavy loads. Improve pad “bite”, improve wet weather performance, continuously refresh the brake pad AIRFLOW/COOLING The curved vane disc is directional, and curved vane disc must be installed with the vanes running back from the inside to the outside diameters in the direction of rotation. Orienting the disc in the manner creates a centrifugal pump. The rotation of the disc causes air to be pumped from the center of the disc, through the vanes, and out through the outside diameter of the disc. This greatly enhances the disc’s ability to dissipate heat. Additionally, all of Brembo’s slotted discs are directional, regardless of the vane geometry. The discs should be installed such that the end of the slot nearest the outer edge of the disc contacts the pad first. TECH NOTE: It is a popular misconception that the cross drill pattern determines the direction of rotation of the disc. In truth, for an internally vented drilled disc, the geometry of the vanes dictates the direction of rotation. HARDWARE The coupling between bell, rotor and bushing has been carefully studied by Brembo to prevent performance and comfort problems by defining the correct tolerances for all components and the proper tightening torque.   HOW IT WORKS During braking, torque is transmitted from the disc to the bell through a fastener called a bobbin. This type of mounting system is designed to allow a specific amount of float in both radial and axial directions. This allows the disc to expand and contract under high temperature which reduces stress and increases longevity of the related components. Brembo's unique anti-rattle disc hardware utilizes a spring fastener in order to slightly preload the assembly which eliminates the noise generally associated with floating discs. The floating 2-piece anti-rattle disc hardware system, commonly used in high performance braking systems, was actually developed by Brembo back in the mid 90's.This innovation was initially engineered exclusively for the McLaren F1 supercar which is why the hardware is often nicknamed the "McLaren" spring.
