V7II rear brake noise after tire change
« on: May 09, 2016, 01:49:31 PM »
Just when I was about to pat myself on the back for removing my back wheel for a tire change and then successfully putting it back on, I'm noticing a noise whenever I use the rear brake.  It stops OK, it just is noisy.  Not a squeal or a grind, exactly, more like a loud swooshing sound, especially just before coming to a complete stop.  I don't believe I did anything stupid like get crud on the pads or disk, but I may have.  These are the original pads, the bike has only a little over 8000 miles on it.  Any suggestions from this erudite group?

Could the pads have closed together and the disc slid between the back of a pad and calliper. Steve.

Is it a drilled disk?  A woosh or other noise is sometimes heard as sharp-edged pads cover and uncover the holes in the rotor, especially when coming to a final stop.  I've thought that by tuning the holes you could make the brake play a song . . . wouldn't that be cool?  A couple bars of the factory anthem or your favorite song? 

If you didn't grind the rotor when you did the pads you'll have a little wear-in time that can be noisy.  Also, there is a 'lie' to the pads like your beard hair -- the material is directional.  Until it settles down you'll hear it rub a little.  I don't recall ever hearing it through my helmet though.

You, sir, are either a genius or very experienced (both, I suspect).  That is exactly the problem.  Many thanks.  Now, I hope to be able to rectify the problem without having to remove the wheel.  I hope that I can unfasten the caliper from the holder, pry the pads apart, and, this time, make sure the disk goes between them.  You have my sincere appreciation.  Sam

 Remove the appropriate caliper bolt , loosen the other , swivel the caliper away from the rotor , spread the pads , reverse the process .

I'm amazed that the bike still stopped good.  Easy fix!

I'm also amazed, in retrospect.  It was indeed an easy fix, although I'm concerned that some aluminum on the caliper behind the inner brake pad was worn away by the disk, so now the surface is uneven.  I'll find out soon whether this will affect the braking.
