Narrative:

While at the gate with the boarding process completed the captain noted that he hoped the left outboard brake would cool down. When I looked I noted that the brake temperature monitoring system (btms) indicated it was white and 8; all other brakes were still in the green. I was concerned; but figured it might have been a glitch; as during my enroute inspection; I noted nothing unusual with the brakes. Also; we had this aircraft from the previous flight with no unusual occurrence. We did not have an APU and required an air start. Once we began taxiing from the gate I noted the captain kept the right engine spooled fairly high; during the cross bleed start. Once the left engine was on line he kept both engines spooled fairly high and I noticed the btms now indicated that the left outboard brake was white and 9; the left inboard and right inboard were white and seven. The right outboard was still in the green. We were told to expect a slight delay going into ord and were held short of the runway. The captain set the parking brake and kept the engines spooled up around 40-50% N1. I told him he might want to be careful and go to flight idle as the brakes were too hot for takeoff. He was not concerned. I then explained to him that there was a number that once reached we could not depart. He said he wasn't aware of that; grabbed the QRH and glanced through it. I asked tower how long we could expect further delay as the btms climbed to 10; 9; 9 and 8. I was told to expect takeoff clearance in 30 seconds. The captain explained there was no such restriction noted in the QRH. Then we were given the takeoff clearance; but the captain continued to peruse the QRH. I reminded him that we were cleared for takeoff; but he seemed disinterested. About 30 seconds after the takeoff clearance was given the captain said we would takeoff; but delay bringing the gear up. It was my leg and once at 80 KTS I noted the btms reading 10; 9; 9 and the right outboard showed green.
