View Full Version : Help - need an Avanti Disk Brake Rotor

Replaced a leaking dual Master Cylinder and got the push rod too long which caused the brakes to lock up. The heat caused the front left wheel bearing to fail - so replaced it, no problem. Decided if I replaced the driver side, I should replace the passenger side too. After taking it apart, although the bearing looked good, the race just fell out. Not sure if it's been this way for long, but the rotor obviously has been worn. Does anyone have a good used replacement? If not, maybe this is a good time to switch to the Turner upgrade.
Thanks,
Rich

rich,

sounds like you really need the hub, not the rotor... they are in fact two pieces

Yeesh, Nate, how dumb do I feel. It didn't occur to me that the rotor and hub are separate pieces - they came off as one, and that's where I left it....:-(

Yes, you are correct, what I need is the hub. The outer wheel bearing race no longer fits - the hub has worn to become oversize.

Now I have to go to the shop and look at how the two go together - press fit or bolted.....?

Thanks for replies - appreciate the help.

I believe they are swaged by the lug studs, just like a drum, although IIRC the discs actually went on the backside of the flange contrary to modern practice and the way the old drums went on. so you may need new lug studs as well, even ASSuming your rotor is in good shape and able to be reused.

Normally on a daily driver type car I would suggest if you're going to all this trouble to just buy two new rotors and be done with it, seeing as you're going to just have to do all the pressing and reassembling again at your next full brake job, but I have no idea if they're even available for Studes, and if they are, I'm sure they're pricey.

and no, that's not dumb to assume that they're one piece... most American discs from back in the day are. Studes are different :)

No need to replace anything. Just bring the rotor assembly to a good
machine shop and they can sleeve the hub, then press in a new race.

Pretty simple fix.
