## Discrepancy

FOR FLIGHT 2757 THE CAPTAIN REPORTED THAT AFTER LANDING DURING BRAKING THERE WAS AN AGGRESSIVE TO VIOLENT BRAKE GRABBING.  REGARDLESS OF HOW SOFT THE BRAKES WERE APPLIED, THE BRAKES GRABBED HARD AND ERRATIC.  THE AIRCRAFT WAS REMOVED FROM SERVICE.  REMOVED AND REPLACED THE BRAKE CONTROL UNIT PER EMB MM 32-41-02.  THE OPERATIONAL TAXI CHECK WAS GOOD.  THE AIRCRAFT WAS RETURNED TO SERVICE.
