Wheel weights on my Camaro's calipers

Different caliper, different resonance.

I worked as a mechanic for 25 years, specializing in brakes for 5 of them. This is the first time I have ever seen weights, especially wheel weights on Calipers.

Vented Rotors can have weights in them and they can be a "round" weight placed into a cooling fin. Other balancing techniques are to drill into the hub of the rotor to a specified depth, removing material to balance the rotor.

Keep in mind these are stick on weights and the brakes on your car...ANY car get hot. If you were to place your hand on the wheel of your car after stop and go braking in heavy traffic, you would blister your hand. You can imagine how hot the Caliper and Rotor will get! The point I'm making with the stick on weights is over time, the tape will degrade, the weights will fall off and you could end up with bigger brake problems, body damage, rim damage, etc.

I would go into your dealer and have them inspect this. If they know of no good reason for the weights to be on there, and if they can not get any answers from the dealer for these weights, then I would have them removed.

The cars weight distribution doesn't matter that much. Even on a car that has 50/50 front/rear weight distribution, roughly 80% of the stopping power is done by the front brakes. It's simple inertia and weight transfer.

try this... get a tuning fork... or somthing similar

give it a "ding"

attach some added weight to it...

give it another ding...

you get 2 different sounds... (it resonates at a different frequency)



it is overlapping sound waves... like if you are in a tub of water and you move back and forth with the waves (at the same speed as the waves).... the waves compond on each other and get bigger.... this is called resonance

every piece of material has a frequency that causes the sound waves to compond on each other.... this is why a crystal wine glass can shatter when an opera singer hits the same note (frequency) in which the crystal resonates ...




Therefore, if the brake rotor causes the brake caliber to vibrate at its resonant frequency... (by friction) .... it will resonate (squeal)... even though it is not moving.

add weight... different resonant frequency... no compounding of the sound waves

that actually mad sense to me lol

Reguardless. There should be a TSB on the item. Hopefully to be issued soon.

It's improper to have the customer take delivery without at least an explanation of something like that. Brembs are supposed to be Pimping Bling of Braking Excellence. Not a Wal Mart fishing weight kit.

I was kind of thinking the same thing earlier, with the tuning fork. Add weight or some kind of mass and it would dead'en the sound some.

So, I'm bored, and figured this might be appropriate:
http://www.cotronics.com/vo/cotr/newprod.htm
High-temperature adhesives. That page shows adhesives that are rated for 3000 degrees F. If those weights are pure lead, their melting point is 623 degrees F. I don't think it's necessary to worry about the adhesive, I'm sure they would have used something like that. How about the lead...I'd assume they used an alloy good for at least 1000 degrees.

A 2000 degree adhesive is accompanied by this picture which coincidentally looks a lot like a brake pad:

Uh, that IS a brake pad. And It appears the point of the picture in relation to the article is that the adhesive that they use to put the pad on the metal base is this type of adhesive. So then we can conclude that adhesive CAN be used to last on brake callipers.

Great find dude.

But back on topic, Has anyone asked the guy that works on the line in oshawa about this? Ask him to check it out in his thread and maybe he can get an answer faster.
