## Discrepancy

DURING A 50 HR OIL CHANGE AND INSPECTION, FOUND BOTH LT AND RT BRAKE PADS FALLING APART, SEVERELY CRACKED WITH LARGE PIECES MISSING.  BOTH SIDES WERE CHANGED AT THE PREVIOUS 100 HOUR INSPECTION.  THIS HAS BEEN A FREQUENT PROBLEM WITH THESE BRAKE PADS ON ALL OF OUR AIRCRAFT (2 C152, 1 C172, 1 C172RG), NEW PADS FAILING WITHIN 200 HOURS OR LESS SINCE WE STARTED USING THEM. PREVIOUSLY, WE USED OTHER MFG PADS WITH VERY FEW PROBLEMS.
