Narrative:

Climbing through approximately fl 220; brakes hot ECAM. Leveled at fl 260; per ECAM slowed below 250 kts. Extended gear; cooled brakes below 300 degrees; slowed below 220 kts; retracted gear. Continued to filed altitude and realized that we had exceeded maximum operating altitude for gear extension.contacted maintenance to advise.while focusing on slowing for speed limitations I did not recall the altitude limitation for gear extension. Recall limitation for gear extension.
