Leveraging the technology it has cultivated through the development of brakes for high-performance vehicles, Akebono has developed an opposed-type electric parking brake caliper for sports-type electric vehicles.

This is the world’s first design in which a single piston in an opposed-type caliper serves both the service brake and parking brake functions. This design achieves significant weight reduction and is also capable of withstanding the high-temperature, high-load braking conditions typical of circuit driving.

Akebono has developed electric parking brakes for small- to mid-sized trucks, featuring a unique construction in which the output of a single motor is transmitted to two pistons via two spindle mechanisms.

A key feature is that generated output exceeds that of comparable mass-produced products from other manufacturers by 200%, and for which the company has obtained a patent. In addition, patents have also been secured for the incorporation of a differential mechanism that adjusts the output balance between the left and right sides, as well as for the integration of an electromagnetic clutch capable of maintaining parking clamping force.

The required electric current is 14 Amperes, equivalent to that of existing products for passenger cars, while weight is reduced by more than 3 kg per vehicle.
