Narrative:

First officer was flying a normal approach to runway 22R ord. A normal landing ensued; wind correction added. I assumed control of the aircraft and applied brake pressure. Up to this point; we were on the centerline and I continued to apply brake pressure. I noticed degrading brake action with increasing left pedal inputs and no activation of antiskid. I continue to put more and more left pedal correction until I reach the left stop. The aircraft continued at a rapid pace to the right side of the runway with maximum braking effort being applied and no antiskid activation. Within seconds we were off the runway and came to a stop.

Title: E145 EXPERIENCES BRAKE; ANTISKID MALFUNCTION ON LNDG ROLLOUT AT ORD.

Narrative: FO WAS FLYING A NORMAL APCH TO RWY 22R ORD. A NORMAL LNDG ENSUED; WIND CORRECTION ADDED. I ASSUMED CTL OF THE ACFT AND APPLIED BRAKE PRESSURE. UP TO THIS POINT; WE WERE ON THE CTRLINE AND I CONTINUED TO APPLY BRAKE PRESSURE. I NOTICED DEGRADING BRAKE ACTION WITH INCREASING L PEDAL INPUTS AND NO ACTIVATION OF ANTISKID. I CONTINUE TO PUT MORE AND MORE L PEDAL CORRECTION UNTIL I REACH THE L STOP. THE ACFT CONTINUED AT A RAPID PACE TO THE R SIDE OF THE RWY WITH MAX BRAKING EFFORT BEING APPLIED AND NO ANTISKID ACTIVATION. WITHIN SECONDS WE WERE OFF THE RWY AND CAME TO A STOP.
