CURNO, Italy – Brembo, the world leader in braking technology, has worked closely with the engineering team at Karma Automotive to provide a lightweight, low-drag brake system for the new Karma Revero GT luxury electric vehicle.
The Brembo front caliper is a six-piston all-aluminum monobloc caliper. The one-piece caliper is designed to provide the 370 X 34mm rotor maximum clamping power. The low-drag design of the caliper, with a specially designed retraction spring to keep pads from dragging on the rotor, will aid increasing the range of the vehicle. The axial mounted caliper is very stiff, with the only moving parts being the pistons. The six pistons are staggered in diameter, 30/34/38mm, to allow for even stopping pressure on the 115 cm2 brake pads.
On the rear, a four-piston Brembo caliper will help to stop the Karma Revero GT and its 536 hp. The aluminum rear caliper is also a low-drag design and carries a brake pad measuring 52.3 cm2. The low drag design coupled with the Revero GT’s regenerative brakes will also increase brake pad life.
To complete the system, a Brembo Electromechanical Parking Brake (EPB) is also a component of the brake package for the Karma Revero GT. The Brembo EPB system replaces the standard parking brake, which is usually manually operated by a mechanical lever in the driver compartment. This lever and all cables and mechanical links are replaced by an electronic button located with the driver controls reducing weight and complexity. The EPB delivers a 1.7 kg (3.8lbs) per car weight savings over a typical drum-in-hat system.
“The extremely lightweight braking system for the Karma Revero GT combines the stopping power that Brembo is known for with our low-drag technology to minimize as much rolling resistance as possible,” said Dan Sandberg, president and chief executive officer, Brembo North America. “The impressive horsepower capabilities of the Revero GT can propel the car from 0-60 in four and a half seconds and such performance demands the best in stopping power. Brembo brakes enable a seamless transition between regenerative braking and friction braking. The low drag caliper maximizes fuel economy and EV battery only range.”
