You need to clean the calipers, whether or not they need replacing can only be told once you have them torn down. Most likely they have a little bit of corrosion and just need the disposable bits replaced. I took pics when I tore down and rebuilt the brakes on my 700S, it shouldn't be that much different from your 450. http://nighthawk.kylemunz.com/?p=430
