It was 23 degrees outside when I got in my car at work to go home. I pulled out of my space as usual, and at the end of the parking lot drive, which was on a downward slant, I stopped without incident before entering the road. Brakes worked.

Then I drove a short way going at about 15-20 mph, for less than 1/8 of a mile, and as I approached the next stop sign, I applied my brakes, and to my horror, the car kept rolling. The brake had gone down about half-way, I think, and there was no noise or vibration. Luckily, no other cars around, and I cruised through the stop sign and swung right, and all of a sudden, my brakes "caught" and I started slowing down. The whole thing lasted only a couple of seconds. The road was perfectly dry, nor had I driven through any water/snow/ice earlier that morning. After that, my brakes worked fine through the rest of my 30 mile trip. My car is a 2002 Nissan Altima, and the front brakes had been serviced < 6 mos ago. Any ideas? Can cold weather do this?
