Here's an auction for something I've never run into before: Brake shoe weights for the A-body 9" drums. I see this package listed in my '73 FPC, but can't imagine what it's for. Anyone know?

Mmm...I'm not so sure that'd work so well. Look at the small contact area where the weights would attach to the shoes.

Gut reaction,

Vibration or harmonic dampening add on. Curious.

That's a reasonable-sounding guess. Maybe with the tweaks and fiddles they made to the 9" brake system for '73, they wound up with brake noise that could only be killed by increasing the brake shoe mass. Pretty amazing the lengths they went to in order to keep using the cheapest possible brakes! :shock:

And perhaps in the process moving the mass center.

I asked if the seller could e-mail me a copy of the directions. If he does, this may shed some light on the subject.

Does any one have a list of TSB's for these vehicles? There may be something there.

This is a response, to posting a question about the weights on the IATN

Those cars had a brake squeal problem. Chrysler came up
with these weights that you bolted to the shoes and it
absorbed the vibration so no more squeal.

Occurs to me that the "squeal" might've been useful in some situations, as a secondary public warning system.

"Lord, Martha, git outta the way o' that thing. Cain't ya hear it?"

:lol:
