Narrative:

Received aircraft from inbound crew with brake temperature monitoring system deferred. I had contacted company maintenance to see why the system had been deferred. They felt the system was giving an erroneous high temperature. As we started to taxi it took an exceptional amount of power to brake-away and we hadn't rolled very far when the temperature of #3 brake began to increase. The first officer and I began to discuss whether we were having a brake problem. I asked him to check airport analysis for the gradient of the taxiway. About the time he found the correct page, ground control queries, 'where are you going?' we had gotten so involved with the brake problem we'd taxied through an intersection (J). We were supposed to hold short.
