Brembo and Polestar collaborate for refined brake system performance
Monday, June 29, 2020
Brake specialists Brembo have announced that they are producing a two-piece 4-piston aluminium front caliper and exclusive dual-cast floating brake disc for the new electric Polestar 2.
The new caliper features Polestar inspired design cues that the company say are crisply sculpted and proudly Scandinavian. In line with the Brembo design method known as “Stile,” the Polestar 2’s brake caliper is a marriage of Italian Style and Scandinavian simplicity. Accenting their lightweight aluminium construction, Polestar highlights the aero sculpted Polestar 2 calipers with a distinctive copper gold colour.
“Brembo is a proud partner on the all-new Polestar 2,” said Daniele Schillaci, CEO, Brembo SpA. “This was a collaborative development project with the Polestar team that results in a caliper that compliments the overall styling theme of the Polestar 2. When you combine the progressive copper look with the technology of this beautiful lightweight brake system, you get excellent stopping power with a distinctive appearance that also promotes sustainability, helping to increase mileage and battery range.”
The Brembo front caliper is designed to provide the 375 mm X 35 mm disc with maximum clamping power. The low-drag design of the caliper keeps pads from dragging on the discs resulting in quiet braking performance, reduced rolling resistance, and improved battery regeneration. The four pistons have the same diameter and are offset towards the trailing side which avoids tapered, uneven, wear of the pads.
The dual-cast floating brake disc is made of two materials, cast iron and aluminium. This new disc offers reduced weight (15-20% lighter), greater driving comfort, less corrosion, less wear and better brake performance. During operation, the disc effectively maximizes performance by functioning as an integral disc at low temperatures, then as a floating disc at high temperatures with minimal distortion.
