Front Wheel “brushing” sound on left side

[LeftCoast]

Hi all, 2015 used RTL with 20k miles with Continental rear tire and the bike had 15k when I got it, I had the 18k mile service a few months ago and they replaced front brakes and rotors. I’m now hearing a rubbing or brushing sound that seems to be coming from the left side in the rear. Is that a brake wear sound? I would have though that when they did the service they would have let me know the rear pad didn’t have much wear left.

Thanks in advance.

The rear disc's on the other side, isn't it? Well, mine is anyway!! So if it's coming from the left it might be the belt, or maybe a rear wheel bearing? Altho, just last night I was trying to sort out a belt guard that the belt was rubbing up against for about 1/3 of every rotation on a GS; and I've seen a few of the a/mkt 'Missing belt guards' that've been fitted incorrectly that do scrape a bit when the suspension flexes to the offending position - so there's another possibility?! Have you tried to find the source of the sound by hand spinning the rear tire with the Spyder lifted off the ground?? :dontknow:

:agree: with above post. Left side rear I would think it would be belt or belt guard. Brake is on the right.

Thanks Peter and Copper I haven’t tried lifting the bike because I have no way to do it. I am not mechanically inclined btw, although if I could get the bike off the ground I would be able to spin a tire :roflblack:

No missing belt guard on this bike. I do have a friend though that may be able to help me get it off the ground.

And yes disc is on the right. I may just ride down the street no helmet to confirm what I’m hearing

As I have offered before, I can help with that for sure.... I am far away relatively but hey, the offer still stands....

Thank you hyperone I do appreciate your offer (and the others) and may take you up on that.

Well I stand corrected. Just zipped up and down the street and the sound only happens on deceleration and primarily from left front. I’m going to admit I don’t know if there is a break in procedure for new brakes and if there is the shop didn’t inform me. I’ve just been riding as normal.

Yes, there is a break-in process - it's six consecutive hard stops from 30+ mph. If the pads were properly installed, they were sanded and beveled before inserting.

So anything I can do at this point or should the shop have done that? And maybe they did btw

Come up to Rich’s house on the 18th, we can figure it out. Joe

You can perform the "break in" procedure at any time. It may not be as effective as when the pads were new but it can help bed them in better. Do 3 medium pressure stops from about 35mph (without stopping fully) then 3 hard pressure stops (again without stopping completely) and then just cruise for 10mins to allow some cool down, then repeat the procedure again. This time from 50-55ish mph. Once done make sure to keep riding for 20-30 mins to allow full cool down before you park it....

Thanks all. I’ll try today and let you know
