brake-functions FSX and FS2004

Hello all,
I ran into a problem which I do not know where to search for the solution. :-/
I have two separate buttons assigned to the left brake apply and right brake apply function. Behind both functions I have set the repeat slider completely to the right, so it keeps repeating as long as pressed.
However, in both FSX as FS2004, only the left brake does function.
The right brake does not show any effect... :-[
The buttons are recognized by both sims, so this cannot be the problem.
Somebody who noticed the same and knows how to solve it ?
Thanks in advance ! :)
Bram
