In order to determine the size of the brakes on your Montana you will have to pull off the wheel and the hub and drum assembly. Then you will measure the inner diameter of the drum and the width of the surface the pads make contact with in the hub. I have included a picture showing the measurements in question.

You may be able to look at the back of the brake assembly for the make and model number stamped into it. With that information I may be able to determine what brakes you have.
