Lowering Rear Brake Pedal Height?

[2whlrcr]

Is there anyway to lower the rear brake pedal more? I have mine all the way down and it's still 1/4 higher than my pedal. Plus in this position there is very little free play and the brake is like a light switch. I am used to running my pedals much lower and have never had an issue setting them up, until this bike.

If you cut the the threaded adjustment rod and shorten it, will this help move the pedal down and still give you adequate free play? Any thoughts?

Thanks
