Question Brake rotor rivets

My first corvette, a 76 that has 89,000. The break calipers are leaking, i need to replace calipers, that much I understand. What i don't understand are the rivets on the Rotors. Why are they there? 3 of the 4 rotors have rivets. The first rear wheel I pulled did not have rivets, I drilled the ones on the other back rotor to get the rotor off. Now I find them on the front wheels. Do I need to re-rivet the rotors? How critical is it to put the rotors on the exact same way they came off. Any help would be appreciated.

The rivets are there to hold the assembly together at the factory.

To get the rotors off, you will need to drill the rivets out. You do not need to put rivet back in, the wheel lugnuts will hold the rotor on.

You will need to replace the rivets only if you are going for an NCRS judging, they will count off points for missing rivets, but mechanically, you do not need them.

BTW, Welcome to DC!

some recommend that before removing the rotors you should mark both the rotor and the hub to ensure putting them back in the original position.

just be sure to line up the hole in the rears for your ebrake adjustment.

if you are unsure of the rotor position, you can throw some lug nuts on them and run an indicator on the rotor to check for run-out. should be no more than .003". if it is over, rotate them one lug hole at a time to get the best reading. use shims made from pop cans if needed.

in the rears, you might have to drop the half-shaft to ease in turning the rotor.


and the fun part............how are the ebrakes?
