Any advice on rub sound from front tire - Page 2

glenski · 08-07-2008, 07:49 PM

I looked at mine and there is some minor wear showing where it could perhaps be filed down but nothing serious. I suspect my problem is that the pins weren't properly lubricated and as a result they caliper wasn't floating like it should. I just took them all apart and lubricated the pins (they weren't very well lubricated) and took it for a quick drive and it seems to have taken away the intermittent rub sound. All told the job took 35 mins which includes me dragging my tools out of my apt and dragging them back in. Not a bad job at all.

Wow! A lot of really good advice. I need to go change out of my suit, put on some grubby clothes and see which of these suggestions it ends up being.

This forum is amazing. Now if I could just figure out how to get the internet dealer to send me my MCO!!!

Thanks again,
David

A quick way to check if one side is rubbing more than the other is (carefully) feel the rotors right after you get done riding, see if one side is hot and the other isnt.

As thin as the rotors are i think the heat would dissipate(?) right through and not be able to tell any difference from one side to the other.

Brand new pads squek a bit, or you can file the edges down to stop that. Check the fork alignment my LB200-2 came ascew a bit.

I have a new SL-200-2 and I am experiencing the same issue.

Here are some details:

Its definitely coming from one of the calipers (I removed the left one, rolled the bike around and no sound, put it back on, sound came back).

It seems to be louder/more pronounced when rolling the bike backwards.

I lubed the caliper pins/back of the brake pads/etc and the sound went away for roughly 2, 30 minute rides.

The sound is similar to an old door when opening/closing it (kinda a ooohhhh oooohhhh groaning sound)..

I took it back to the dealer and we took it apart, where he checked bearings/etc but he couldn't find anything.. He said the sound should 'go away' after some use..

I would rather fix it. Any suggestions??

Make sure the friction face of the pad is flat.

If the disk is really hot, it's rubbing and you could try bleeding the breaks.

I'm no pro just what I'd try.

I am almost embarassed to write this (since the solution is so simple)..

I think I figured it out.. I was in the middle of removing everything AGAIN and noticed that the right caliper was now making the sound with the left caliper removed. WTF!!

I then noticed that the right brake line had no slack.. So I popped it out of the chrome hook holder thing, spun the wheel, and, no more noise.. :idea:

I then reinstalled the left caliper, did not put the brake line in that chrome hook holder and, as you can guess, no more noise..

Its raining cats and dogs here in TX so I have not road tested the 'fix' but it seems logical that if the chrome hook brake line holder isn't positioned right that it wouldn't allow any give in the flexible brake line which would significantly limit the calipers ability to float over the rotor and thereby cause some rubbing/noise..

It appears the fix is to bend/move the brake line holder..
