I just finished reinstalling my fork legs and front wheel after changing the fork springs. My front brake drags a little on the brake pads when I spin it. Is this normal? It doesn't stop the wheel dead, but I can hear it rubbing while it spins. Any suggestions? Thanks, Schmitty | ||

Normal. And you want to know why, right? Okay... As I understand it, It's a side effect of the type of calipers/pistons used on the XB. As you apply the brake, the pads tighten. As you let go, the pressure is relieved. However, it's still got some frictioin to it. This is also a floating rotor, so as the pads are "free" so is the rotor. So I think that most of it is just a byproduct of the Rotor. Hence, you're gonna get some noise. Is this my opinion? Nope. I had a GREAT MECH explain this to me one time. HE even drew a picture. His explaination was like 20 minutes long, so I'm trying to cut it short, but if you look at your caliper and the pistons without pads, and compress the brake, you'll see that the larger piston is first to compress and then the med. and then the small. They don't all compress at the same time. It will make sense once you do it without the pads. The largest piston is last to "uncompress" so it's always got a bit on tension to it. Goofy, but that's just the way it is. My Ducati 900ss did the same thing. |
