recently purchased new front rotors for my 1979 vette and when i went to change them ran into problem with hubs being mounted to rotors with some kind of rivet or other fastener wondering what the next step is to changing rotors do i grind rivets ? do the rivets need to be installed in new rotors ? thank you


now that i have seperated the hub from the rotor do i need to rivet hub to new rotor or not? why were the hub and rotor rivited in the first place?

you have to drill them out ...do a search, there is lots of info on this.

I don't remember mine being riveted. Someone must have been there before me. My rears, however were riveted to the hubs. Center punch the rivet. Start with a smaller bit and work your way up to bigger bits to step up to the size needed to get the rivet to turn loose. Worked great for me.

What's wrong with your existing rotors? Are you aware that you'll need to measure and correct any run-out on the new ones?

Center drill the rivets with a ¼ drill bit. This will leave only the outer ring of the rivet and the rotor will come off.

You can then install the new rotor and check it for run out. If the run out is excessive you may try moving the rotor position around.

Excessive run out can cause early bearing failure and/or allow the caliper to suck air.
