Narrative:

I was working on an EICAS status page message 'alternate antiskid' 'normal antiskid' on aircraft xyz. While troubleshooting, I found the #8 wheel speed transducer faulty. Upon removal, I was clearing the placard and saw that the #8 brake was disconnected and capped. Per the MEL, a disconnect tool (abc-def, cpn wwvx) was required. That part is not stocked at ZZZ or at the station that placarded the brake. I assumed that the brake was only disconnected at the brake itself, so I reinstalled the brake line to the brake.

Title: A B767-300ER WAS DISPATCHED AND OPERATED IN NON COMPLIANCE WITH THE #8 BRAKE DEFERRED BUT DEACTIVATED INCORRECTLY.

Narrative: I WAS WORKING ON AN EICAS STATUS PAGE MESSAGE 'ALTERNATE ANTISKID' 'NORMAL ANTISKID' ON ACFT XYZ. WHILE TROUBLESHOOTING, I FOUND THE #8 WHEEL SPD TRANSDUCER FAULTY. UPON REMOVAL, I WAS CLRING THE PLACARD AND SAW THAT THE #8 BRAKE WAS DISCONNECTED AND CAPPED. PER THE MEL, A DISCONNECT TOOL (ABC-DEF, CPN WWVX) WAS REQUIRED. THAT PART IS NOT STOCKED AT ZZZ OR AT THE STATION THAT PLACARDED THE BRAKE. I ASSUMED THAT THE BRAKE WAS ONLY DISCONNECTED AT THE BRAKE ITSELF, SO I REINSTALLED THE BRAKE LINE TO THE BRAKE.
