Speedbrake on landing

[berny33]

Hello,
On landing although the speedbrakes are armed (green light on), they do not unfold.
An idea ?

Possibly thrust levers not idle at touchdown?

Cheers, Jan

Thank you for your reply.
I made several landings with a view of the cockpit:
I notice that the speedbrakes are well to the touch and then move down automatically. That's why I thought they were not complaining ...
Because in fact the plane needs a great distance to stop! (autobrake on 3!)
