How to break a mechanism in Episode 28? (Age of Pirates: Captain Blood)

I can't figure out how to break this damn mechanism. There are 2 levers, the character comes to the lever, the inscription "Break the mechanism" appears - the "B" button on the XBOX 360 joystick (I play it), I press "B", he grabs the lever and starts to pull it back and forth and ... Nothing happens! The mechanism has a scale of "health" (strength), but it does not decrease from these twitches. I remind you that there are 2. How long should you wait while he pulls? What's the trick? Is this a bug in the game? Has anyone encountered this incident? Can I get through this?
