No problem, I think it just takes practice no matter what your hand size is. I'm not understanding the part about the brake lever being adjusted close to the bar and not having enough room to brake with two fingers? Are some of your fingers between the lever and the bar? If so, I don't think that is a good idea, should be nothing between brake lever and bar. The throttle gets rolled with the lower palm of the hand while braking with the first two fingers. Practice till it becomes second nature.
