New Brembo co-casting disc for MIMS 2017

8/22/2017

The new Aftermarket range of Brembo brake discs offers an innovative solution that is both lightweight and resistant.

Brembo, the leader in the braking system industry, is a key player in the 21st annual MIMS Automechanika, Russia's main automotive trade fair. The Company will be unveiling the new co-casting Brembo brake disc.

This disc was made to replace the composite discs in the Aftermarket range for the most recent premium applications on the Mercedes - for which Brembo is already the OE manufacturer - an option that maintains the technical and performance specifications while adopting an exclusive and highly innovation solution. A steel housing is obtained through a pressing process, and is then positioned in the mold during the casting before the liquid cast iron is introduced at a temperature of 2,552°F. It is subsequently connected to the braking surface as the cast iron solidifies around special steel teeth on the hub.

The result is a lightweight disc made up of a high-carbon cast iron braking band and a steel housing, which are properly coupled during a special casting process that ensures perfect interchangeability with the original disc as well as increased performance and reduced weight.

Brembo co-casting has the following characteristics:

1. Resistant
The special build of the steel housing and its connection to the cast iron band through casting enable unifying the two parts and the two different materials, while increasing the disc's resistance to thermo-mechanical strains.

2. Lightweight
and drivable The steel housing guarantees about a 15% reduction in the weight of the disc, compared to an integrated disc of the same size. Since the brake disc is part of the unsprung weight of the car, reducing the weight improves handling, which results in more precise and stable vehicle dynamics and ensures more driving comfort.

3. Low environmental impact
In recent years, environmental impact has taken on an increasingly important role. The co-casting solution adopted by Brembo respects the environment by reducing the weight of the disc, which in turn ensures an increase in the available force and a reduction in consumption and emissions of the car.

4. UV-treated surface
The disc surface is coated with UV technology, a highly innovative, state-of-the-art option. By choosing to do this, Brembo guarantees a disc that is more resistant to corrosion, humidity and elevated temperatures. Plus, the UV coating is water-based and does not require solvents, which makes the coating process very efficient from the point of view of energy: it generates a savings of 98% in energy and emissions.
