Brake is either 0% or 100%

I just got the moza r5 bundle and everything seems to be working well. i don’t have any issues in the moza app on my brakes but when im in game it’s either not braking at all or it’s fully braking. did the test buttons thing on the settings and basically it doesn’t brake at all when im pressing the pedal but once i get to the end of the pedal and i’m pressing it fully the braking is 100% and there’s no in between. i don’t have the same issue with my throttle or wheel and it seems fine on the moza app. any ideas on how to fix?
