Clean everything very well then allow a couple of days for it to leak, then inspect it again. I just rebuilt my Brake pump assembly and installed a new accumulator, not as hard as it sounds. Mine was leaking from the inlet tube rubber fitting on the motor assembly. I have pictures if you would like a walk through on how to do the rebuild. The pump o-ring is the biggest problem. Its a square-cut ring and the fluid will distort and enlarge it over time. Just make sure your o-rings are the correct type for brake fluid. The reservoir to master cylinder assembly is another likely spot for leaks to occur. My o-rings come from a assortment kit we use for aircraft. You local NAPA or Auto Zone should have an assortment you can chose from. Buna-N O-rings work.
