Squeaky sound coming from brakes
#1
Hi, there, first time poster here!

I am a little desperate in my naive attempts to fix what is going on with my bike for years and it looks like I'm totally hitting the wall. Hope that someone might chime in and hint me on some way to fix the issue...

So, I bought a KENT SHOGUN T1000 HYBRID - MENS Model # 22798 bike (http://www.kent.bike/22798/shogun-t1000-hybrid-mens) around 3 years ago from my LBS. It has been making quite weird sounds when braking from the very beginning, but the LBS owner convinced me it was normal and that the sound would go away after first 75-100 miles.
Well, it hasn't. I came to the store again after ~200-250 miles, he changed the brake pads (and charged me A LOT for doing this) ... and nothing really changed in terms of sound. Then I moved from the area, haven't used my bike for almost 2 years and now I'm trying to get back to cycling.

So that's what my bike sounds now - https://youtu.be/nYmjb8z_eIQ

And a couple of close-ups of the area where my brake pads touch the rim surface.

I honestly tried all I can think of - I tried changing brake pads to brand new ones - it even became worse, so I returned the old ones back.
I tried gently sanding a rim surface with Dremel thinking that if it is too "flat", it might make these sounds - no results really.
I even checked ball bearings in the wheel in case they were the source of the sound, but likely no.
As a matter of dangerous experiment I tried oiling my brake pads with some silicone spray ... and the sound pretty much went away... along with braking ability Smile

So now I seriously struggle about what to do next. After that service from my LBS I really don't want to invest anymore into this bike at least unless I am sure it will not be just a promise again, but rather a solution for the problem. Any ideas why this might be happening? I haven't seen/heard anything like that before on any of my bikes, though I have to admit their rims were mostly steel and looked a little different.


Thanks in advance for any help!

Squeeks can drive one nuts, some one can live with but not a lot. First clean with a solvent and sand your pads lightly on a clean flat surface to by laying a piece of sandpaper, 80 grade or so. on it and using a figure 8 movement. Than clean the rims with a solvent . Make sure your wheel bearings are lubricated and set properly. Now put the pads back in and set then so they toe in slightly in the front. Make sure the brake moves smoothly and does not vibrate when you brake. Good luck
Never Give Up!!!
