DURING POST FLIGHT, NO LEAKS WERE NOTICEABLE & FLUID LEVEL WAS FULL FOR THE TEMP.  THE BRAKE PUMP MOTOR SOUNDED LIKE IT WAS RUNNING CONTINUOUSLY & WAS EXTREMELY HOT & SMELLED HOT.  REMOVED AND INSTALLED AN OVERHAULED BRAKE MOTOR ASSEMBLY, HIGH PRESSURE SWITCH AND LOW PRESSURE SWITCH. PERFORMED OPS CHECKS WITH NO DEFECTS NOTED.  WORK DONE IAW AMM 32-42-00.
