Opposed Piston Type
Disc Brakes

The opposed piston type is a disc brake which has pistons on both sides of the disc rotors.

The opposed piston type is a disc brake which has pistons on both sides of the disc rotors.

The opposed piston type disc brake features stable braking force as well as a high level of controllability.

The swept areas of the brake pads are enlarged to increase braking force, and here opposed piston types are favored. This is because of its advantage where the number of pistons can be increased to realize even distribution of pressure on the rotors from both sides. Depending on size of the brake pads, there are several types, including the 4-pot type which has two pistons on each side for a total of four, and the 6-pot type which has three pistons on each side for a total of six.

Akebono also develops and manufactures 10-pot brake calipers for high performance cars. This type has five pistons on each side for a total of ten. This brake caliper is suitable for large-sized high performance cars where brakes are subject to heavy loads, since large size pads are required for superb stopping power.
