Brake Rotor/Hub Question
I'm building a '64 mid-year and am looking at converting-over to front disc brakes. I got a pair of '68-'82 spindle, steering arm, rotor/hubs. It appears that the rotors are rivited to the hubs, Can I grind the rivits off from the inside to separate them, or am I stuck with the combination? Thanks for any help to a guy from the C-2 side.

dave you drill them out from the out side and then they seperate.....the trick guys then tap the holes and use counter sunk set screws to fasten the rotor to the hub after shimming for runout......or the rest of us just put them on and hope for the best. you need to be aware that the rotor run out with the calipers will cause the original lip seals to suck in air....the o ring seals do not have this issue......so if after you are all finished and you cant explain why you get a mushy pedal feel after having firm brakes and bleeding always fixes the problem check for rotor runout...or just bleed the offending rotor/caliper when it get mushy.

Index the rotors before removing the rivets. Reassemble with your witness marks and run out will be minimized.
If you are intending to have your '64 judged, you do not want to make this swap.

My car is a restorod. I got the hardware for some old Chevelle parts and was hoping this wouldn't be a real expensive upgrade.
Why would I need to resecure the rotors to the hubs? Did all you guys have to go thru this when it came time to replace your rotors? When I replaced rotors on my '95 Chevy truck, I just put the new ones on the hubs and that was it. I'm not arguing, I'm just asking.
Also, when I look in the Mid-America, Zip, etc and all they're selling are hubs and separate rotors.

You don't have to replace the rivets the lug nuts will hold them on, but you must index the rotor and hub or you may have run out problems. PG.

OK, index. Do you mean ensure the rotor goes back o the hub in the same location? If so, I got that and understand.
Now, Bob, you mentioned shimming them. Why would I need to shim the rotors - or do you shim them if replacing them with new rotors?

You only need shims if you have run out. Check out part 12 & 13 on this link for more information on C-3 brake run out. http://www.idavette.net/Hib/vette_BBFH.htm PG.

The '69~'82's have the larger diameter spindle/bearings, right? I've got the larger diameter spindles. Thanks for all the help. Now, I guess I need to get the rotors mic'd. They may not need to be replaced at this time.
