Brembo engineers design each brake upgrade specifically for your vehicle and driving conditions. Optimum brake balance is achieved by combining Brembo's thorough knowledge of OEM braking systems and use of an unlimited range of caliper, piston, and disc combinations. Brembo brake upgrades are easy to install and designed to work seamlessly with your vehicle’s stock master cylinder, ABS, and traction control system.
Most OE calipers are of a sliding design, with piston(s) only located on the inboard side of the disc. While this type of caliper is inexpensive to manufacture, it is generally extremely heavy, and inherently flexible under braking, which significantly degrades performance. Conversely, Brembo's calipers are a fixed radial or axial mount design with opposed pistons and constructed from aluminum alloy. Despite being much larger and many times stiffer than the sliding OE caliper, they are also much lighter which benefits overall vehicle dynamics.
The caliper body has been designed to be as light as possible while meeting stiffness criteria.
Calipers are available in the standard colors of black, silver, red and yellow. Dedicated track enthusiasts will want to stick with black as this is the most durable color.
Each Brembo system is delivered with preloaded calipers. Brembo calipers are equipped with unique pad retaining features and sequential piston bores in order to provide even pad wear and optimum performance. Quick Release Pad Retaining System: Incorporates anti-rattle feature (pictured) to eliminate noise and is designed for quick and easy pad changes.
Brake pads are selected vehicle specific for high performance.
The GT-R option
The 640i and 650i kits are available in the GT-R option. GT-R stands for Grand Turismo Race and monobloc calipers are machined entirely from billet with a nickel plated race finish to provide both the features and benefits of a racing brake system. This includes improved stiffness and thermo-mechanical resistance which is critical in high-performance applications.
GT-R's twin seal design provides race level performance without compromising the low maintenance aspects of a Brembo OE system. Ventilated stainless steel piston inserts are incorporated for heat rejection. The unique recessed dust seal design provides increased protection at elevated brake temperatures....another Brembo innovation.
Caliper Mounting Brackets
All Brembo caliper mounting brackets are designed vehicle and system specific. They are precision milled from superior quality billet materials to ensure a precise fit and meet the strength requirements of high performance driving conditions. Brembo brackets are also further analyzed and tested to ensure fatigue life.
Brembo caliper mounting brackets are also anodized to provide an attractive finish.
Each Brembo system includes all necessary hardware for ease of installation (please read instructions prior to installation).
Part numbers are clearly laser etched along with an unique serial number (S/N) for each part.
Pictured, are a few examples of axial and radial mount bracket designs.
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.
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.
DISC THERMAL CAPACITY
A. Mass: The area located in the outer ring of the disc (shown in orange), dictates thermal capacity. This consists of annulus, width, diameter, air gap, and vane design.
B. Annulus: The area between two concentric circles. This dimension directly correlates to the friction surface area of the brake pad.
C. Disc Width: The overall thickness of the disc. Calipers are designed for a specific width.
D. Air Gap: The area located between the rotor plates surface is airgap. The amount of airgap is a crucial factor in channeling airflow.
E. Vane Design: Exclusive venting system that improves cooling capacity which increases resistance to brake fade.
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 (orange colored area in the diagram shown). The more mass located in this area, the more thermal capacity a disc has.
• 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 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
Type V and Type III discs are an option for enthusiasts seeking to improve rotor longevity.
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.
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.
Stainless Steel Brake Lines
Each Brembo GT kit includes a set of stainless steel brake lines manufactured by Goodridge. Goodridge is the leading line supplier to OE manufacturers and championship winning race teams worldwide. With the tightest bend radius in the industry and the lowest rate of expansion, you can be assured that every inch of pressure from the pedal is transfered directly to where it counts - the caliper. Goodridge is the only brake hose system approved for use in every country in the world and it's guaranteed for life.
Goodridge High Performance Brakeline race-bred street brake lines are constructed from the finest quality hose, consisting of a PTFE inner hose covered by braided stainless steel. In addition to providing a more responsive and firm brake pedal by eliminating the “spongy” feel that often accompanies stock rubber brake lines, High Performance Brakelines are abrasion and corrosion resistant to stay good looking for a long time to come.
