New Genuine Knorr-Bremse with one year warranty.
Spring Brakes are used for supplying the service and parking brake functions on axles fitted with air disc brakes. The internal wind-off device permits elimination of the parking brake power if the air pressure is no longer present. The Spring Brakes have an integral mounting seal inside the non-pressure housing that prevents dust or water from reaching the caliper.
