i have almost 9K on my 8 and the brakes squeal like crazy. i know there is a TSB out for this, but instead of going to the dealership, explain my problem, maybe/maybe not argue with the service writer that i should have the TSB, drop off or sit there and wait...i decided to just do it myself for a quick 15-30 mins.

- all i basically did was remove the front wheels
- remove the 14mm bolt from the bottom of the brake caliper
- swing the caliper upward
- remove the brake pads
- clap all the dust out of the little groove in the center of the pads (this is what makes the squeal)
- sanded the pads with either sand paper or brillo pad
- applied anti-seize to the back and sides of the brake pads

drove about 50 miles today around town and haven't heard a squeal yet!!

my dealer told me that it is just some sort of build up from the air and that every now and then, NOT all the time, just get going about 15 or 20 mph, and just slam on the brakes to sort of "scrape" off the build up. it helps temporarily, but not as long as i would like. i may try your idea and see if it works.

no...the slamming of your brakes won't work. believe me, i tried that. along with spraying a shitload of brake cleaner and blowing all the dust out with compressed air. there is a groove/slot going down the center of each pad. brake dust and metal shavings collect inside of there and basically cake up, causing that horrible squeal. driven almost 1000 miles since i've done it, still no squeal.

cool. now i got me a weekend project thanks

Short, usefull, informative post. Thanks.

Will try it too.

Thanks for the info, but what's anti-seize? Somekind of WD-40?

anti-seize is lubricant that protects parts from rusting or seizing up. it can withstand high temperature.

I installed my winter wheels yesterday and was really surprised to find that the brake squeal, which was very bad, has completely disappeared. Possible I shook loose the dust?

this fix is just a temporary fix. it eventually came back on me as the dust accumulated in the brake pad vent.

Rumor Has It Another Recall On Brake Squeel.

Maybe Ceramic Pad Replacement Compliments Of Mazda?

Can Anybody Verify?

MEGAREDS

My "fix" was temporary, and I've been living with it almost consistently for 2 1/2 years now. It went away for a brief time after they changed out the pads. In the winter I don't usually notice, but during the summer it's annoying.

I'd love to see a real solution. Please post any news...

Just clean the pads out when they start to get really dirty again. It really doesn’t take the long. Most of the time you can get rid of it by taking off the wheel and spraying water with a hose in between the pads on both sides of the rotor. Takes way less time than driving to a dealership, waiting and arguing with them, and taking it back.

come to think of it - i've noticed my squeal goes away for a little while after I wash the car . Interesting - will try this idea next time .

the squeal you hear is high pitched vibration between the pad back and the caliper piston

clean everything spotless and glue it all together with brake anti-squeal goop

something like this, all kinds of similar products at most auto parts stores:

Sorry to bring this back, but wanted to ask Team:

After my track day, I started getting squealing on hot days...really LOUD squealing. So, I'm going to take the front pads off and clean them and apply CRC Disc Brake Quiet. Does this go between the back of the pad and the shims? Or should I just get rid of the shims altogether? But then I would have to put goo on the calipers themselves...doesn't sound right at all. Please set me straight.

Silver_Surfer

For me I removed all pads, cleanned and applied BG anti brake squeal to the pads. So far about 3 months no noises.

I am very new to DIY, and still reading up as much as I can before I even start to tackle any projects. Don't bash me too hard, I just am looking for clarification.

Where exactly do you apply these silencers? Seems like putting some kind of goop in your brakes would screw up braking, so if it's not going in between the calipers and pads, where is it going and how exactly does that stop the squeal?

phxtravis

You use the "goop" where ever the caliper pistons contact the pad, and the use a lubricant(I use the Synthetic Brake Grease from CRC) on all other moving parts(except the pad/rotor surface, duh!). I Havn't had a single squeak since switching to Hawk HPS pads and Powerslot rotors.

Thanks for the reply.

Anyone know a good place to go to learn about the braking mechanism as a whole? I need to learn more car vocabulary and what makes up each system in a car.

How did you guys start out in your tinkering adventures? So far I'm just reading everything that catches my eye, but what I could really use is some singular starting point to understanding all the basics.

If you are not going to be a mechanic the best way to really learn is by doing but get hold of a workshop manual before you start . Having a freind who has done a lot of this kind of stuff help you is a great way to learn as well .

If you want a good primer on how modern disc brakes work and how they can be optimized, go to www.stoptech.com and check out the white papers and FAQ...I'm not saying their opinion is definitive on all points, but they know their stuff and the web site is a good resource

Thanks much guys!

DO NOT REMOVE THE SHIMS ..those are anti rattle shims..you need those. and you got it right it goes between the back of the pad and the shims... i like to put a little bit of it on the caliper but only where it contacts the shims/pad...also clean off the old crap that on shims and caliper too..what you should do too so that your brakes dont get to hot..is run some tubing from your front bumper to your rotors..like 2inch to 3inch tubing..should work just fine. :wink:
