## Discrepancy

(CAN) BOTH THE RIGHT AND LEFT HAND BRAKE CALIPERS HAD A PIN HOLE FLUID LEAK. BOTH CALIPERS WERE LEAKING ON THE OUTSIDE SURFACE IN THE CORNER OF WHERE THE RAISED CIRCLE ACROSS FROM THE BRAKE PISTON BORE IS. BOTH WERE ON THE SIDE CLOSEST TO THE BLEEDER SCREW. THE CALIPERS WERE REMOVED AND LIGHTLY PRESSURIZED FOR A FEW HOURS ON THE BENCH AND WITH A 10X MAGNIFYING GLASS YOU COULD SEE A WET SPOT OF HYDRAULIC FLUID FORMING.
