front brakes dragging?

I was riding around this morning and noticed a brand new annoying sound from my 07650. @ first I stopped to see if the front tire had a slow leak, it sounded similar. The best I can figure is the front brakes have started dragging for some reason. When I started the ride this wasn't happening, 50 miles later it was. Sort of a low level hiss/grind sound. I used the search function and only found a rear brake dragging thread. I understand that a little drag is normal, but what gives? Anyone ever notice this sound from their front brakes?

I wear earplugs.

I know mine drag slightly but, if the wheel rotates okay and the brakes stop the bike when I want, I don't worry about it.

I don't wear earplugs on my motorcycle and can't fathom why someone would unless they had an ear infection or rode a harley they didn't like. I also eat bad foods and smoke occasionally. I can imagine this sound/dragging happening if dirt or grime got underneath the pad from off roading, but I had just washed it and my morning ride was on relatively clean paved roads. Anyone have crap get stuck under the pads after off roading that caused this same prob? If so, did brake cleaner do the trick or did you have to take the pads off?

Do the front rotors over heat if so then you have a brake drag that needs attention. Brake pads sometimes become contaminated by dirt or what ever else you may get into, remove the pads and sand them with coarse sand paper on a flat surface. Reavaluate your noise, dual purpose tires will sometimes make the front fender vibrate and make a odd noise under braking. Resently washed brakes will also vibrate and make noise. Does the noise go away if you apply the brake lightly? A light hissing noise is normal, PS if you can hear this noise while riding, purchase and Wear Ear Plugs you are blessed with great hearing, don't destroy it.

It doesn't go away w/ light brake application. Tried that first; no change in the noise.

if you have recently removed and reinstalled the front wheel, it might be slightly out of kilter. doublecheck that all the spacers are correct and retorque all the nuts and bolts. likewise the caliper mounts. put your bike on the centerstand and put a crate or something underneath it so that the front wheel is in the air. the wheel should turn freely ... some friction, but not much.

after a number of years the pistons/seals of the calipers can become scored, and need to be rebuilt. since your bike is an '07, that seems unlikely.

the only other thing i can think of is your rotor is warped. unbolt 'em and lay 'em on a flat surface. that will tell that tale.

WOW JWT! Are you going to let this guy tell us you have warped rotors?

In public!


Geeze TouringDude, ease up on the guy...

Or maybe take it to Spank?

you joke, but i swear, i half expect someone to jump on me and say, "you think they're warped because you are a feeeeeling liberal! you need to trust your guts! it's a central intelligence thang (CIT)." LOL!

holy crap, i swear, i laugh my arse off over some of that stuff. can't believe it is said with a straight face.

Hissing Brakes

I, too, recently noticed a hissing/scraping sound coming from my front rotors. This was while I had a passenger and had to get on the front a bit at a light. Eyeballed the pad widths and they should be nowhere near the wear line. Rotors look clean. This is an '07 as well. I can nearly feel the scraping through the brake lever (or at least the sound makes me think I do!).

If the noise does not change or get worse on apply it is most likely the pad compound.
