Narrative:

August 2010; I was assigned to an aircraft on the ramp in ZZZ. While debriefing the [flight] crew; I was informed that the crew had written up the aircraft to have a 44 minute brake cooling inspection. At this time; I finished my walk around inspection; released brakes; and went to tend to my other aircraft while the 44 minutes required [time] passed. I got back to the aircraft to do my brake cooling inspection. While performing the tire pressure portion of the inspection; I noticed the # 4 main tire was flat. I felt I needed to focus on that problem because I didn't want to hold up the ramp personnel from loading the aircraft; which was due out at xb:00. I contacted my lead to inform him of the situation and ask for help. I then went back to the maintenance shack to gather my supplies (tire cart; tire; jack etc..) and to print a copy of the maintenance manual and open maintenance items. The tire change was accomplished without incident; and was signed off at xa:41 local time. I then asked my lead to contact fueling; and I informed the ramp personnel that it was safe to start loading the aircraft. At the end of my shift; while waiting at the time clock; I had a conversation with a fellow mechanic about our respective nights at work. I told him about the # 4 brake cooling and tire fuse plug; and he asked me if I changed the brake too because he thought it was needed per the maintenance manual. After I clocked out; I asked another mechanic I know if this was true. He said it might be but wasn't sure. At that point I turned around and went back into the maintenance center to look up the maintenance manual and look at the brake cooling inspection. When I read item 1.B.(4) and realized the brake indeed should have been replaced; I immediately contacted company management to start a report process. I did have a copy of the maintenance manual for the tire change and the 44 minute brake cooling inspection; but my focus on the flat tire problem is the main reason why the brake change was missed. After I disclosed the information to company management; aircraft maintenance was contacted at the next arrival station and the brake was changed.

Title: A Line Mechanic reports he did not notice in the Maintenance Manual that a brake change was also required when he replaced the #4 main tire that went flat at the gate from overheating. Mechanic notes he was focused on having the aircraft ready for departure schedule and failed to see the wording for the brake change towards the end of the tire change procedures.
