Brembo Releases Its New 'Extrema' Calipers

F1-derived units showcased on new LaFerrari

Brembo is already known as an innovative leader in the automotive industry especially when it comes to brakes. But now, the company has a new trick up its sleeve. The new 'Extrema' Brembo caliper is made specifically for higher end sports car. Brembo comments, "a product designed to meet the demands of an extremely demanding and continuously evolving market."

One of those evolving market demands is weight reduction. Brembo has mastered this by hollowing out the caliper, which translates into approximately 6.6 pounds of non-suspended weight, and better feel through the pedal. In addition to weight reduction, the caliper also has impressive ventilation resulting in a reduced brake fluid temp of 86 degrees F. The new caliper will initially be offered in nine colors (one being anodized).

This particular caliper is derived from Brembo's work in Formula 1, and these are some additional impressive features of the new 'Extrema' listed by Brembo:

Given the high loads generated by the pressure of the pistons on the pads, maximum stiffness and minimal deformation are assured by adopting a monobloc design, in other words the caliper body is machined from a single billet of cast aluminium.
The front calipers are equipped with six pistons specified with dissimilar diameters to ensure uniform wear on the pads, which otherwise would deteriorate more quickly on the disc entry side.
The rear calipers have four pistons with dissimilar diameters. The pistons are equipped with heat shims and drilled radially around the circumference engaging the pad, in order to attenuate the transmission of friction heat to the brake fluid in the hydraulic system.
