Rear Brake Rotor Replacement Questions
I've got a 1976 Corvette, that I am currently rebuilding/customizing. Now my question is how do you get the rear brake rotors off?!? I drilled off the rivets that hold the rotors onto the hubs on both the front and rear. I got the front rotors off with little effort. Now the rear rotors have been nothing but trouble. First I drilled the rivets off and the drilled inword about a 1/4" into the rivet studs, but the rotors still do not want to budge. I am not going to use the old rotors so I have not been worried about damaging them at all. I have heated them up with a torch, drownded them with penitrating oil, pried, hammered and cussed, with no luck. So any help in this matter will be great. Thanks, Dan.

I did'nt have much trouble with my 78 rears but I had a similar problem on my wife's Expidition. I used a large two jaw puller with quite a bit of tension on it and kept heating the rotor in the center with a rosebud tip, once it reached the temp it needed to expand, it popped off,good luck and be carefull.

I got both of the rear rotors off last night (thank God). I had to use a little more heat and I drilled the studs out a little bit more. Thanks for your help, Dan.

RE: Rear Brake Rotor Replacement Questions
The factory rear rotors were trued after attached to the hubs. Therefore when you put the new ones on, you will want to check the runout at each of the five mounting positions. I believe the spec was 0.005" max but not sure. If you have too much runout, it will move the pistons back and forth in the caliper bores and will eventually cause air to be pumped in. This will result in spongy brakes at best and no brakes at worst.
Recommend installing the stainless steel parking brake kit. Stainless crossover cable is a good idea also.
