My wife rides a 1999 400 sport and it takes more hand strength than she has to stop it. I have rebuilt all calipers new sintered pads all the way around and no change it has about 6 hours on the new brakes. Our 94 Trailboss stops much better , if she needs to stop in a hurry it won't happen its all i can do to stop the 400. I hope someone can help Thanks, David
