## Discrepancy

DURING WALK AROUND TECHNICIAN REPORTED #2 BRAKE WAS SMOKING AND REQUIRED REPLACEMENT. ON REMOVAL OF THE BRAKE, PIECES FELL OUT OF THE BRAKE ASSEMBLY. TECHNICIANS HAD TO REMOVER TIRE AND BRAKE TOGETHER TO GET THE BRAKE OFF AS IT WAS SEIZED. GROUNDED - YES. REMOVED AND REPLACED #2 MLG TIRE AND BRAKE PER B737-9 AMM 32-41-41 & AMM 32-45-11. OPS AND LEAK CHECKS GOOD.
