How is this a "better" solution? Guys we are heading in the wrong direction. I haven't been to the CTS-V forums but I would guess they aren't having this problem.

It looks like the caliper from the Porsche is from the Cayenne SUV not a 911 or even Cayman/Boxster. I have yet to see these balancers or weights as they are called on any other car wearing Brembos. There is a guy on here who installed the 6 piston caliper from Brembo.....no weights or squealing.I am no engineer but something just doesn't add up. My guess is there is something happening with the Camaro specifically.

your right... your not an engineer...



be rest assured ladies and gents, if those dampeners didn't need to be on there; they would not be.


say what you want about GM's financial and executive team... but their engineers dont waste time engineering something and then validating it unless it's needed.


it's a necessity, if you dont like it... feel free to find a better solution that matches a 100k mile warrenty.

Mine just started the slow roll squeel and I have to tell you I don't care how ugly they are if they work... Nothing sux more than rolling along in a nice sounding rumble Camaro, looking shiney and fine and then touch the brakes and SQUEEEEEEEEEELLLLL....

If it stops the squeaking who really cares? If anybody asks what they are, just tell them they contain high-torque miniature electric motors that contact the inside of the wheel and activate at speeds over 50 mph to increase fuel economy.

The problem is it doesn't stop squeaking on all the cars... brake weights, then roller skates.. how about replace the whole caliper? and stop putting band-aids on it.

I do see that these are part of the new pad assemblies from the factory, so changing to any other available pad will likely NOT have these added weights.
DO NOT PUT ANY TYPE OF LUBE ON YOUR BRAKES!

I hope GM not have to pay for that bad Brembo's or sue the damn Germans !!

Why don't they put some USA-made brakes ?? Baers/Stoptech (are that USAbrands ? )

I expect that the poster means to apply the lube to the points where the pad backing plate sits in the caliper. Inadequate lubrication at those points contributes to squealing.

Brembo = German? Try again.



FWIW I think this is a technically and aethstetically superior solution. The pads are what makes the noise so it makes sense to put the dampeners on the source. I used to put little aluminum (I think, maybe tin) shims on brake pads to quiet them down.

Do I think it could have been done better, yeah probably. Everyone has a budget and GM is struggling. I'm sure there just isn't a ton of $$s around for stuff like this. Like one other poster said, it isn't going to stop him from buying one.

Obviously these dampeners are on the cars for a reason if you guys hate it that much come up with a better solution

Best thing they could do, short of redisigning the caliper. Maybe they'll do that as time permits.
Getting them? You mean paying for them? Or taking it in to the dealer for warranty repair because of squeaky brakes?

This is a haphazardaly attempt to delete brake harmoics that are typical of this design flaw. By adding additional unsprung weight is a deterient to the handling characteristics of the suspension geometry - further thought would be appreciated to the Engineering staff at GM.

Much Appreciated, Thank You.

Very odd design

BMW have some cars with dampener weights added to the calipers too - but they are designed to blend into the line of the caliper - these look very strange - never seen anything like them before.

Just surprising that after nearly a year the fix looks so "Heath Robinson"

ok, so some people on this thread pointed out that it would be a problem if you tried fitting smaller rims than the stock 20''.... would it have trouble as well if you tried installing a bigger brake disc???

I agree. This makes the crappy weights that are already a part of the early camaro's look great in comparison. Let's hope this is fixed for the 2011 model year.

Like I said I'm no engineer....I am however a bit of a thinker.

If there are dozens of car models out there with Brembo brakes, it would seem logical that the Chevrolet engineers could have copied the Ferrari, Bugati, Porsche, Cadillac, and Chrysler engineers' solution to the squealing brake problem.

Unless of course you feel those engineers AND the ones at Brembo couldn't validate why the dampeners were necessary. I'm not dumping on the engineers at GM. I am simply stating there is more to the story. What is it about the Camaro that makes the dampeners necessary?


// End MY rant.

You are correct it is from a Cayenne.
my 4gen has Porsche GT3 brembos onit and the factory pads has the dampers on the them also. Just Porsche designed its dampers on the backing plates as to not be such an eye sore.

Yeah, I took JICPerformance the same way. Definitely put the lube on the contacting metal parts on the back of the pads. At two connecting points on the back of the outside pad and one connecting point on the back of the inside pad where the round master cylinder makes contact. It's worked for me before and a good point made. I'm gonna find the best break quiet lube I can and put a bunch at these points and hope it shuts up the embarrassing squeal.

Harmonic dampening technology is used frequently in other industries, too. In the picture below, you can see high voltage transmission lines using harmonic dampeners to cancel out wave motion induced by wind or earth quakes.

The dampers on high voltage lines take many forms, but the most basic is that of two heavy lead weights attached near the end of each line segment near the transmission line support tower or pole.

Not pretty and very low tech. I think I like my Camaro's early stick-on lead weights better than the latest incarnation of the damper.
