Pneumatic disc brakes from Knorr-Bremse become even more efficient and energy-saving with the APR®-System (Active Pad Release) or ACR®-System (Active Caliper Release), the upgrade for brake pads.
APR and ACR - two systems for maximum energy efficiency
The two technological solutions APR and ACR systems provide truck and fleet owners with a simple but effective retrofit solution for trucks, buses and trailers that use Knorr-Bremse 22.5” pneumatic disc brakes.

Both solutions help to save fuel and also reduce particulate matter emissions. These effects are achieved by reducing the residual drag torque after the braking. The APR-System is currently available as a retrofit solution for vehicles with brakes of the SN7 and ST7 generations. The ACR is specially designed for the latest SYNACT® brake generation. In this way, heavy commercial vehicles can be further optimized quickly and easily. Not just a brake upgrade, but a game-changer for your braking system.
Cost-efficient and sustainable - how APR and ACR work
In both, the APR-System and ACR solutions, the brake pads and brake disc are actively released from each other via a spring system. Both systems offer the advantage that the active resetting of the pads significantly reduces unwanted friction. The residual brake torques are therefore significantly lower, which in turn decreases fuel consumption and lowers CO2 emissions. Less friction also means less wear: brake pads equipped with APR-System and ACR wear more slowly, remain in use for longer and therefore produce fewer particulate matter emissions.
