Change Physics2D.maxTranslationSpeed at runtime does not work

Hello.

I'm still using Unity 5.3, so I'm not quite up to date.

I'm trying the following:

 Physics2D.maxTranslationSpeed = 1f;

It compiles with no error what so ever, but the value of my maxTranslationSpeed remains unchanged. I don't know to to do to update this value corretly.

When I change the player's material bounciness, I need to disable and enable again his collider, otherwise the change also doesn't take effect.

Is someone can help, please, I already looked around and coudn't find anything related. Thanks o/
