C3's Brake/rotor-vents with sleeve-pin Inserts???

[Vette/Berlina-coupe]

-wonder if anyone has ever seen what i just discovered on the Rt.front Brake-rotor, three adjacent vent-slots have slotted/cylindrical-pins (like the type you would see used as a drift-pin to hold a part on to a shaft for example) that appear to be possibly someones attempt at balancing the Rotor itself! I can't imagine that this is a factory-fix, although the car only has 15k-miles on it, and the rotors are all smooth (no signs of ware). My concern is that if one of these apparently hammered in place 1/2"-diam.expansion-pins were to dislodge and thereby radially jam against the brake-caliper while driving at speed, it could obviously instantly lock the one-wheel and thereby throw the car out of control into a violent right-turn !! Would greatly apperciate anyone having any knowledge about this sort of balancing practice, -and also how i might go about removing these three pin-devices. The previous-owner was up in years, but did say that a Race-driver friend named DarylWaltrap had tuned-up the car's suspension for him, to attain better ride and handling, --maybe this is an old NASCAR Rotor-balancing trick, but it scares me silly! Please advise... ~Bob vH :confused

Come to think of it, I saw the same thing on at least one of my rotors (maybe more, can't recall). I seem to remember only one large roll-pin in there - I could be wrong on the number of them, but they were definitely there.

Any ideas?

Bob,

I gotta say that your posts are really hard to read! Have you got a picture of what you're talking about? I don't recall ever seeing the type of pin you are describing.

Sounds like an attempt to balance the rotor but instead of adding weight I drill holes to remove weight from the heavy side. Spring pins are just that , springs that hold themselves tight in place. I feel if you started to come out it would be clipped by the rotor and not even come close to stopping the car. It would bend over instantly and you would not be bothered. They are hollow, collapsable with plies and not enoough to stop the car.
