C2 front rotor replacement

[Larry Seaney]

The front pass. rotor on my 67 has excessive runout (.0085) and a thickness of only 1.160. So I assume replacement is in order.
1. Is there any special way to drill out the rivets holding the rotor to the hub.
2. Can anyone recommend a vendor for the replacement rotor?
3. Does the new rotor need to be riveted to the hub? Who does this if needed?

Thanks for the help.

Larry www.bairs.com can do the rivet work. They also sell parts.

All you need to do is ***** punch the centers of the rivet heads and step up in drill bit sizes until the head rwists free. Then it's a matter of drift punching the remainder of the rivet out through the back side of the hub.

Make sure that the drift is long enough where it won't get hung up in the rotor if it bottoms out befor the rivet falls free. Some times they're a bear to get back out of the hole if the drift's tapered shank is driven in too tight.

All the usual vendors will carry replacement rotors. Bair's, Ecklers, Vette Brakes, etc. etc. etc.

The rotors don't need to be re-riveted to the hubs as the lugs will keep it in place unless your into the "correctness" deal.

All you need to do is mount the new rotor and snug it up with the lug nuts and check for run out. After you rotate it to the best position, mark the location for future reference and you should be good to go. Just make real sure that the mating surfaces are next to spotless so that they mate together correctly or your run out measures will be incorrect.

Larry,

If you happen to live in Southern CA, I know a shop that rivets new rotors to your hubs. He has a press set up for this purpose. Anyway, if you have a drill press it really helps. The rivets are 5/16". Use a center punch to mark the center of the rivet head, then using a 5/16" bit, drill just deep enough to go through the head,(you don't have to go any deeper) then drive them out with a heavy duty punch and hammer. If you have someone locally rivet the rotors back on, make sure they install the lug nuts first and torque them down to the hubs before installing the rivets. Good Luck...

Thanks for the tips. I got the rotor and hub separated and ordered a new rotor from Vette Brakes (10% disc for NCRS members).
