What is the reason everyone puts them on is it because the parking break sticks and chews the pads off. This seems to be what happens to me with my 300ex. It seems to eat the pads right off it. If I dis connected the parking break would it save me from having to put rear pads on every few months. I bought the bike used over a year ago and havn't touched the front brakes but I have gone through a couple sets on the rear.
