Whatever the reason, it screams ghetto. If there's not some really good reason, I'll be knocking them off mine.

For the real answer look at my post, its 3 up....
nice drawing lol


and what about the adhesive that holds them on wouldn't that melt or come off well before those temps?

I would say they will all eventually fall off. I'm starting to wonder if this thread is all a big joke. If so, haha good one.

I would have to agree! I'm sure the adhesive will fail and they will fall off with continuous heating and cooling cycles along with water, dirt, and anything else that will come in contact with them. If anything I would have to guess and this is far fetched but this is my best guess. I think this might be a way of "tuning" the suspension, I have seen testing done where they "jounce" the cars suspension on a machine to test dampening properties. I would guess those are atleast 1/2oz weights which would mean there is right around 1/2lb of weight on the caliper. I don't know if they would go to this extreme but for the handeling characteristics, WHO KNOWS? I think adjustable shocks would do the same job but then cost goes way up!!!

There will probably be a future recall to replace all the calipers with a revised version. There is no other reason I can possibly think of except to change the vibration characteristics of the setup. Basically you lower the resonant frequency when you add mass. So in certain braking conditions they must squeal, squeak, chatter or "ring" badly enough to require this band-aid.

The breaks don't move/rotate to have a resonant frequency. Also, it's only on the fronts apparently.

What happened to your previous proclamation of Brembo requiring it for some stupid warranty agreement? Quit trolling.

There is a slight possibility that this is true.. sad, but true.. Only way to find out is to remove them..

The warranty thing was a joke. But everything has a resonant frequency, it doesn't have to be a moving part. And don't call me a troll

Is it possible that it's some type of wheel positioning sensor that is used for stabilitrack?

see that's what I thought besides being a tire pressure reader for the OBD tire pressure readout but have researched both technologies...and nothing comes close

It's been a very long time since I've seen that but back in the ol' days.... '70s-'80s, they were used to balance the brakes during stops. i.e.-- Prevent vibrations during hard braking! I assume this is for the same reason!

Weights on Brake Calipers

Gentlemen As far as the brake weights go I heard from a fellow in the GM plant, the brakes were squeeling and by weighting the calipers the squeel went away Brembo has, since then sent a new batch of calipers to correct this problem Hope this helps

Does that mean there might be a possible recall for early production Camaros, to replace the brakes?

The weights

Gentlemen;

Wow, I never thought this would create such an uproar. THe car was at the dealer last night for an Eastern Michigan Camaro Club meeting and several opinions were thrown around. One member had a theory and it seems plausable about the weighting, far be it for me to question it as well. Finally the President of the club suggested we contact Scott, he will, and we'll end this when we get that answer. Sorry about the dirt on the inner wheel. We just spent the day driving around town when I was cleaning them is when I noticed the weights. Also I am going today to lay out the stripes with the painter and will update with pictures when they are done. I know a few will be disappointed when the stripes don't go all the way down the front but it was recommended that we don't go into the front bumper for paint matchin reasons. I will be glad to share to cost figure when I get it.

haha, i posted last night saying that a mass damper like this would be a piss poor way of fixing an NVH problem, it sucks being right... oh well at least they are addressing the problem appropriately in the future

Wheel weights on my Camaro's calipers Part II

I feel this is an important issue. For those of you who are getting your Camaro's with the "quick fix for the squeally brakes" problem," I definitely think you should have your dealer order the "corrected brembos" that others are getting.


The reason behind the problem answered by Camkid54

Folks, this thread wasn't created in order to be a b*tch and moan session, but to be informative and for an answer to be found for the 2 owners that have these pieces on their brakes.

Future off-topic posts will be removed.
