## Discrepancy

AIRCRAFT WAS NOT GROUNDED: FLIGHT CREW REPORTED THAT THE LEFT BRAKE MADE A VERY LOW PITCH SQUEAL WHEN THE BRAKES WERE APPLIED AFTER LANDING.  BRAKING ACTION WITH THE LEFT BRAKE WAS INCONSISTENT- SOMETIMES IT WOULD GRAB HARD, AND OTHER TIMES YOU WOULD HAVE TO PUSH THE PEDAL DOWN A LITTLE FURTHER THAN EXPECTED TOGET THE BRAKE TO ACTUATE.  BRAKE TEMP NEVER EXCEEDED 305 DEGREES. MAINTENANCE FOUND THE #1 BRAKE WAS GRABBING AND REPLACED IT PER AMM 32-42-27.
