Brake settings gone after a few races

Hello turn ten

I have the logitech g920 , and i have a problem, in the advanced settings on forza6 , i set the brake pedal end at 30 procent or els i cant even brake.
All thats no problem, the problem is , that when i play a few games online, and after say two games, the brake doesnt brake any more, now i have to push the pedal in with almost,
20 kilo of pressure, then i have to go back to the menu, and advance settings, there all what i have set is still the same, but then i have to push oke again, and then i can race again and the brake works again, untill maybe two races again, .
I did send the wheel back, and got a new one, thinking the problem is solved, but no, its still here.
Does anyone now, how to fix it, or does anyone have the same problem.

Greetings

After plugging in the wheel, make sure that you calibrate all 3 pedals by depressing them to 100% of pressure; including the brake. The wheel base one calibrates the steering wheel automatically, the pedals have to be done manually. This is most likely the reason you feel as though your brake pressure is changing after a could of races. I have the same wheel, and I depress all 3 pedals before any gameplay; either on my xbox or on my PC. This includes the brake, it is actually very easy to get it to 100% pressure without too much force.

Thanks for the tip, ill try.
