Ok so here is what I have. I bought this 300ex off a guy and he put it together with a couple of different machines. Here goes:

It is a 300ex frame with a 84 200x swing arm and a 91 kawasaki ex250 ninja motor. He extended the frame in the middle about 6 inches so the bike engine would fit. He put front brakes on it but no rears. So my question is, what do I need to get to put rear brakes on this atv. I guessed 200x disc brake and 200x resevoir, caliper and master cylinder but if I use the 300ex brake peg will that match up with the 200x stuff. I'm in real need here with those of you that know more about this than I do. Am I on the right path here? Thanks in advance for the help.

If it doesnt match up make a bracket or drill new holes, it wouldnt be hard to install the brake.
