Sound Deadening Spray??
Could someone elaborate on this stuff??
When I pulled the wheels to bleed the brakes I noticed a dry film on the backside of the wheels and hub..
When I read about sound Deadening Spray, I assumed this was what it was...
Brakes never really squeaked before, now they squeak just a little.. But logic tells me that the two cant be connected
Brake squeak should come from the Pads Vibrateing in the Caliper not the wheel vibrateing against the Hub..
And this Sound Deadening Spray would cut down on Road Noise or something like that..
Then I see Refrences to Sound Deadening Spray in Threads regarding Changing Brake Pads..
Im used to putting the Goo on the back of the pad, not spray..
So someone educate me on this..
What is it??
Where do I put it??
How much do I use??
Who makes it??
Where can I buy it??

RE: Sound Deadening Spray??
I know in my industry there are a few companies that make a sound dampening spray that is used like dynomat (if you know what that is) it goes on the inside of the vehicles metal panels to reduce vibration caused by road noise, engine noise and vibrating panels from speakers (they claim it will make the stereo louder) never heard of putting it outside the vehicle, just the brake quiet goo like you mentioned. I do know rubberized undercoating is very similar to the sound dampening spray.

i know the rubberized undercoating work pretty well i had that in my crx i gutted the interior and used it on the whole car and it works pretty good, although dynamat is much better i have it in my accord and it does make a big difference on the sound quality of your system and as well as road noise, i have both front doors and the entire trunk covered in dynamat. the downfall is that it adds a good amount of weight to your car

Sound deadening spray serves the same purpose as the goo, but I like the spray because its applies evenly and you don't have to use your finger to spread the goo. You find it at auto parts stores. I use CRC Disc Brake Quiet (Autozone??), just read the instructions on the can.

Yes there is such a thing as spray that you apply to the back of your brake pads when installing them to keep them from squealing. It's called Disc Brake Quiet and is available at any auto parts store. It comes in either an aerosol that you can spray the back of the pads with like spray paint or a paste like that you simply spread with a knife or similar instrument.
Yes, it really does go on the back of the pads. I don't understand it but it works. It is beyond my intelligence level to figure out how putting something on the back of the brake pad is going to stop them from squealing. But I have used it and can tell you it really does work.

hazletbassist89 yes that is the perfect explanation. It does work alot better than most people think here is what I tell customers about it (which usually ends in a sale, even though I HATE installing this stuff): to obtain a 3dB boost in your SPL level you need to theoretically double the power(add another equal power amplifier), a dynamat trunk kit (usually around $175 plus a small additional labor cost to install) will generally yeild a 3dB boost in your SPL levels on the average subwoofer install. So instead of buying another amp at $X you can double your bass.
