## Discrepancy

(CAN) CREW SAID THAT THEY LOST ALL FLUID IN NR 2 SYSTEM HYDRAULICS WHILE ON THE DEICE PAD.  ACFT WAS JUST TOWED BACK TO THE GATE AND MAINTENANCE IS CHECKING TO SEE WHAT THE ISSUE IS.  MAINTENANCE REPORTS THAT THE NR 1 BRAKE IS FALLING APART, AND THE WHEEL ASSY IS SHIFTED ON THE AXLE. THE LT GEAR IS ALSO COLLAPSED.  STILL IN PROGRESS ASSESSING DAMAGE. WERE ABOUT 90 PERCENT SURE THE FLUID LOSS IS A RESULT OF THE HYPER EXTENDED PISTONS ON THE BRAKES.
