BREMBO PRIME TWO-PIECE BRAKE ROTORS
THE SPECIFIC RANGE FOR PREMIUM CARS
Quality and innovation: from our experience in Original Equipment to the Aftermarket
Always a point of reference as a supplier of top range Original Equipment for the most prestigious car manufacturers, Brembo naturally transfers this know-how to the Aftermarket with its most exclusive products, including the Composite, Floating, Co-cast, Lightweight and Dual Cast discs.
In all cases the most performing technical solutions are proposed to the market, such as:
- special cast iron
- pillar or directional venting
- drilled and/or grooved braking surface
Thanks to these technological solutions, Brembo guarantees the highest performance even in extreme conditions, greater resistance of the discs, optimum comfort during driving and a weight reduction of the braking system. The range covers the premium models of some of the most important car manufacturers.
Technical Characteristics
The reduction of the vehicle weight and unsprung masses has been one of the primary objectives of car manufacturers in recent years, to handle the needs for greater reduction of consumption and emissions.
The aluminium hat of the Composite, Floating and Dual Cast discs and the steel hat of the Co-cast and Lightweight discs allow a weight reduction of the disc that can range from 15 to 30% compared to an integral one of the same dimensions.
If compared to the mass of the vehicle, this reduction may seem marginal. However, it actually has a significant impact on consumption, performance and handling of the car, since the disc is part of the vehicle’s unsprung masses.
Floating discs
The range of floating discs consists of 26 part numbers directly derived from Brembo’s OE production. The range covers the most exclusive, top-performing applications, requiring a braking system affording superior performance levels that can only be guaranteed by Brembo’s experience in sports competitions.
Floating discs feature an aluminium hub which ensures a considerable reduction in the unsprung weight, with a positive effect on comfort, road handling and consumption/emission levels. The system performance also benefits from the fact that the disc hub is joined to the special cast iron braking surface with fixing bushes. Consequently, the two components subject to thermal stress can expand in an elastic manner, preventing the disc from deforming and any cracks from forming due to overheating.
COMPOSITE DISCS
The BMW range of composite discs, which is fully interchangeable with an Original Equipment brake disc, features an
aluminium hub that is connected to the special cast iron braking surface
by steel pins.
This technological solution is used on the latest top-performing BMW vehicle range and currently comprises more than 50 different part numbers.
CO-CAST BRAKE DISCS
Used on the latest premium Mercedes vehicles – for which Brembo is already the Original Equipment Manufacturer - the co-cast brake disc consists of a
steel hub which is co cast with the high carbon cast iron braking surface.
This technology not only ensures superior performance for the braking system, but it also allows the
weight of the disc itself to be reduced by up to 15%, resulting in reduced consumption and emission levels and improved
road handling.
The Brembo Co-cast brake disc is not only fully interchangeable with an Original Equipment brake disc, but it has also passed the strictest bench tests and is approved to
ECE-R90 standards.
DUAL CAST BRAKE DISCS
The dual cast brake disc is another exclusive solution by Brembo for the spare parts market, available for the sports models in the Audi, Alfa Romeo, Aston Martin, Maserati and Mercedes AMG ranges.
One vital characteristic of this type of disc is the cast iron braking surface and the aluminium hub, which combine the advantages of cast iron behaviour at high temperatures with the light weight of aluminium.
The brake disc generates a weight reduction of up to 30% (compared to an integral disc of the same size), and a significant drop in both fuel consumption and emission levels. Brembo’s solution also entails a reduction in permanent thermal deformation (up to 70%), improved performance, reduced residual torque and vibrations.
