Brakes arn't slowing me down!!!!

Hello Fellow Aviator's
I've got a Saab 2000 which seems to use more runway than my Boeing 747.
As I use this aircraft frequently, I was wondering if there is anyway of editing the settings to increase the effect of the braking system to help slow me down.
Also, the reverse thrust is almost unoticable, again, is there a way of changing these settings to make it more realistic.
Any advice, suggestions would be most appreciated.
