I was looking for air brake pictures on different fighters, and then I saw a Tornado using afterburner and air brake at the same time! Air brake duty is to reduce speed, isn't it? So why would a fighter burn so much fuel to increase thrust and then use speed brakes simultaneously?

The first photo is from the Tornado Role Demonstration Team's display at RAF Leuchars in September 2012 (source).
That Sep '12 show or its preparation is on YouTube. Most of the instances of the air brakes as seen from the cockpit (looking behind) are followed by the swing-wing extending and the afterburner turning off (you can tell from the sound of the variable nozzle actuators).
While the photos are cool, I'd say it's just perfect timing before the pilot turned off the afterburner while slowing down.
Such example (above) can be seen after 7:40 in this video. Notice the wing position, and from the video notice the aforementioned sound once the wing is extended.
Another possible reason is slowing down for the spectators to see and hear the afterburner. That can also coincide with the fake bomb drop – a pyrotechnic wall of fire, the smoke of which can be seen in the first photo in the question (example below).

Most jets don’t have fuel dumping system so when they need to reduce the weight in a short time they use afterburner to attain a permissible lending weight. However using afterburner causes aircraft to go supersonic very quickly. So they use speed brakes to stay subsonic.

This answer is correct for a small handful of military aircraft, but states "most jets". This claim is utterly, absolutely incorrect. "Most jets" don't have afterburners.
