Recently my brakes have been squealing, and I was surprised at how I cured the issue (for now at least). I was finally getting around to putting on what's left of last season's summer tires, so I thought I'd take a look at the rear brakes and see about killing the noise. I checked the pads and there was plenty left. I looked at the shims and they looked fine... they weren't scraping the rotor or anything. there still seemed to be goop on the back of the pads too.

I was befuddled. confounded, even. where was this noise coming from? I noticed the dust shields. there sure is a lot of dust shielding arond the rear rotors on the 90 Si. I figured maybe they were resonating and screaming. So I took some rubber undercoating spray and gooped them up to try and dampen the any vibrations they were recieving. I took a spin and voila, no more squeal.

not a terribly exciting story, but I thought I'd share it for anyone who was having noisy brake problems that anti-squeal goop alone wasn't fixing.

 

are you sure you didn't just goop up the whole assy. eliminating all possible sources of noise? ha ha just kidding thanks for sharing

 

Is that goop the kind that dries? If it isn't, make sure that goop doesn't get on the rotors/pads.

 

yeah, it's the kind of stuff that dries and leaves the lumpy rubberized coating. I figure the dust shields don't get much heat, so it should be alright

and yeah, I thought of just spraying everythingm but man, imagine the smell :D
