Wheel weights aren't exactly known to fall off, but yeah, it would probably squeak under certain braking conditions. Odds are it wouldn't be something you'd hear all of the time.

 

well lets say it doesnt fall off, but i were to take them off and replace them with a big brake upgrade. would it still make the noise or is it just the caliper assembly itself?

 

I think it's the caliper itself.

You're going to take off a set of 14" Brembos and replace them with something bigger?

 

i didnt say the rotor. i would like to replace the 4 piston with a 6 piston just up front. if i can re use the rotors i will. if not ill just get a bigger rotor for up front.

 

Neither did he.

Now you are talkin'! I think that's what Jake was referencing above.

I don't think a bigger rotor will help at all, since the caliper will still have the same surface contact. Moving the caliper further outboard may require custom brackets made, etc. and you still may not get any advantage from it.

 

he said 14" brembos. the only thing i can think of that are 14" involving the brembos are the rotors.
i dont want to move the caliper out more, i would just see that brembo makes a big brake upgrade kit and bolt in the new calipers. im just assuming that the contact patch is the same with the 4 piston as they would be on a 6 piston. id have to look more into it once i find something out from brembo.

 

Found this on my dealers first SS we got today. Was just about to post what the hell they were doing with the wheel weights until I saw this thread.



That's 4oz of weight :O, wonder how long that glue will last with brake heat unless they are using special weights on these.

 

well. This is an issue. Picked up vin #6046 on wednesday and the dreaded wheel weights were on the fron brakes.
maybe some of you think that this is just a minor detail but I think it's a BIG deal. Those stunning calipers in the open wheel are completely laughed at by anyone who looks at car . Looks like a high school fix.
I cant believe this was not sorted out before cars were shipped and I expect GM to have a fix for this in the near future. I dont see myself taking my car to shows etc...and having these silly weights on there.
Looks like poop.

 

Hello,ground control to major tom,anyone home????? If the weights offend or humiliate you, take the things off. To be honest you can't void a warranty by removing weights of a brake caliper. And they probably only quell a pedal vibration at 90 pulling .85 G's. Think about it? It is going to have to be an extreme situation for 2 or 4 ounces of weight on the calipers to do anything. IMO I'll probably pull mine off the first day to try to find what the problem is and what driving condition causes it. If it's a big issue they'll go back on. If not they are gone. Were not talking brain surgery here.

 

I have enough engineering background to know this isn't true.

 

Elaborate please.....expound......Let's do the technical dance on this

 

 

Let me correct myself. If the weights are hung up front the bad vibe is probably in the steering wheel. On the rear in the pedal.

 

Based on the official description of the problem (post #12), the weights are there to suppress a noise. There is no mention of vibration, which would indicate that the frequency is too high to feel anything.

That in conjunction with the fact that they put weights on the calipers tells me that they tracked the vibration to a resonance in the calipers, and they're simply using the weights to change the resonant frequency of the caliper assembly to a range that isn't encountered during normal driving.

 

ok,using a series of led weights to deaden a high frequency VIBRATION. A sound is created by friction which produces an audible emission usually a harmonic vibration.
