What was found

(CAN) BRAKE PAD WEAR IS UNEVEN. THE TOP OF THE PADS IS WEARING AT TWICE THE RATE OF THE LOWER PART OF THE PADS. THE PROBLEM APPEARS TO BE THAT THERE IS NOT ENOUGH ROOM FOR THE PAD PRESSURE PLATE TO SLIDE ALONG THE BRAKE CALIPER ANCHOR BOLTS WHEN THE BRAKE CALIPER ASSY IS ASSEMBLED ON THE ACFT. THE PAD PRESSURE PLATE ENDS UP BEING PINCHED AGAINST THE BRAKE MOUNTING PLATE AND BEGINS TO FLEX INSTEAD OF STAYING SQUARE TO THE ROTOR DISC.
