Warrior brakes weak?

[maxxdude1234]

I've just noticed that the reverse brake on my 7020 is much much stronger than my forward brake. When driving forward, if I slam on the brake nothing much happens (the are brakes, but very weak), but when driving in reverse and slamming forward the truck stops very quickly and then moves forward.
Just wondered if anyone else has this problem, and if it is normal for warriors. Or is it my error.
