Topic: Big Prob...
in Forum: C3 Engines, Driveline and Handling
I have a big problem and I need your assistance.
The rear driverside brake rotor is not coming off. MY dad and I tried usinga combo of a metal mallet, 8 pounds of WD-40, and a 8" berring puller. We don't know whats wrong All of the other 3 came of fine. WHat should we do?
Thanks guys,

when i pulled mine apart.. two of the four rotors still had rivets in them..
you have to drill them out

Make sure the parking brake shoes are backed off as far as they go. There is an acess hole in the rotor that should match up with a corresponding hole in the axle hub. Some times a groove is worn into the parking brake drum surface, and a corresponding ridge develops on the shoe surface, effectively locking the shoes to the rotor. Besides the rivit issue as pointed out by Ben, try some PB Blaster which is a lot better than WD-40 on rusted parts. At least I have found so. The best rust part lubricant I've used is Kroil, from Kano Labs.
If all of the above doesn't help, try heating up the area on the rotor near where it meets the axle hub with a propane torch, while gently whacking the rotor with a rubber mallet.
Even after owning a Vette for 35 years or so, I still get amazed at the different ways they can piss ya off!
Good Luck

hey guys.... Intresting. The ones that came off didn't have rivets in them, this one does. Does that mean this one never came off the car? Why do the rivets need to come out anyhow, and how do I do it?
Thanks guys,

thats exactly what it means...
be prepared for a real horrorshow when you pull it off and look at the emergency brake parts..
you need to drill the rivets out..
i find it easier on the rear if you take the spindle out. but then youre opening another big can of worms.. its easier because then you can just drill the heads out a little then smack with chisel and then use an air chisel with a pointed tip to knock them out..
it much harder to drill the exposed heads off and usually winds up with you having to drill the shaft of the rivet out.. go get your self 5 cheap 1/4" drill bits... youll ruin any good bit you try to use..

[/QUOTE]It could, but it could also mean that someone replaced the rivets. I have replaced them and I still have some rivets around - they are available. Riveting the rotor to the spindle minimizes runout, especially if the rotors are trued to the spindle after they are riveted on.

Who told you that? Riviting the rotors does nothing. You minimize run out when you use a dial indicator. Rivits were only install at the factory so they didn't fall off when they flipped the frame over
Agree, but I didn't know that was the reason they rivited them on.
