Narrative:

Installed brake #XXXX ordered by other maintenance personnel. Instead of installing brake #YYYY, had no knowledge that this aircraft was a post engineering change order XXX. Aircraft had arrived from hangar to gate with severe hydraulic brake leak. Changed brake and did not notice any difference between old brake and new brake. Parts need to be more clearly identifiable, insufficient time to verify brake part number.
