Brake Squealing

Nartanian · 06-23-2010

This has simply a huge annoyance and is beyond me. I have pulled the brakes off at least 3 times. I can't really explain the sound so I just posted up the vid. The only facts I know is that as soon as I even lightly tap the brakes the sound vanishes and disappears. Also this squealing noise doesn't start right away. It usually starts after about 5 minutes of highway driving or 10 minutes of street driving with moderate braking. This leads me to think that it's a heat related issue. I also know for a fact that is from the driver side rears. Either case, if you have the slightest idea of what the issues may be please lemme know. Also these are new rotors and pads from Napa.

Wheel bearing, in my opinion.

That's what I've been told too. When weight gets transfered to that side it gets worse and when weight is taken off that side it quiets down by quiet a bit. I don't understand why the sound goes away as soon as I applied the brakes though.

Because it aligns the bearing in a way so that it won't make the noise, less force straining the bearing itself. If you turn one way and the sound goes away, then the bad bearing is on the side that you're turning toward.

I would say that sounds like wheel bearing noise, when you step on the brakes it may load the bearing differently, that can make the noise quieter or louder depending on how its worn

Ahh, I remember that noise now, I said something about that last time I rode in it. and how the the back rotor was baking hot blue... 1st guess is air in the brake line, cause of the fact that you ran the master cyl out of fluid. Have to bleed all the brake calipers. Something that we can do tomorrow.

Looks like we bleeding the brake calipers then.
