Narrative:
We were vectored for a left downwind and were cleared for the visual approach to runway 26. We were very familiar with the terrain and threats during a 26 approach to abq. We were cleared for the approach to follow [another carrier] on final. I built the runway with a five-mile extension to intercept five miles at 1;500 ft above the ground. As I was descending through 7;500; around 7;000; we received the 'caution terrain' warning. I immediately disconnected the autopilot and climbed to 7;500; and the warning ceased. We continued the approach uneventfully.before I descended from 7;500; I looked at the terrain on my mfd and only saw light green terrain. I knew there was a large mountain in our vicinity; but thought we were clear of the terrain before I descended. I performed a turning descent which set off the 'terrain caution' warning. I responded immediately to it. I should have stayed at 7;500 and configured for landing and not descended from our final approach altitude until I was within ten degrees of our approach centerline. This would have avoided the warning. I would also request a right downwind if possible when arriving from the west at night due to the terrain positioned just left of the centerline on runway 26.
