Where are they? I cant find them and i am trying to drill them out.

If you can't find them, they're probably already drilled out.

Ja, makes sense...... :D

Here is a pic of the rear rotors. The rivits are the flat round things between the wheel studs. If you have holes there, the rivets are already drilled.

How many rivets are there per wheel? This is on my todo list.

Twin_Turbo

5 per wheel, fronts and rears

Alright then that means they are already drilled out. I am using a puller to pull the rotor off but am not having any success. Is there a better way to do this?

Twin_Turbo

You did remember to loosen the handbrake right???

battsup

uh no, how do i do that?

take a look at the pic that 70 LS1 posted. see that hole in the hub portion of the rotor? If you rotate that so its near the bottom you can shine a flashlight in there and see the star wheel that can be turned by using a prying motion with a screwdriver. its the same way that you would adjust drum brakes. By turning the star wheel it will either tighten or loosen the parking brake shoes depending on which way you turn it. If the e-brake cable is corroded and binding it can also make it difficult to get the rotor off since it may not be releasing all the way.

whether your rotors are already drilled or not, make sure there are no burrs on the mating surfaces, either hub or inner part of rotor, once you get them off. run your fingers over the areas where the rivots were drilled and make sure they're flat and gring them flat if needed. My rivots were already drilled but whoever did it did not de-burr the surfaces and the rotors would'nt sit flat on the hub.

Ah yes, my young friend...you've gone from the very top (carb) down to the very bottom of the car! Here's the deal, if the rivets are already drilled out (which is good because it's a PIA), release the parking brake, lay a 2x4 against the back side of the rotor (so you don't ding it) and give it a good whack with a hammer. If that doesn't work, use a bigger hammer. If it's badly rusted you can spray a little penetrating oil around the hub and let it sit over night and try again. There's some good stuff called LB Buster (I think) that will loosen anything. After you spray it, tap lightly around the area with a hammer to make the metal "ring". This vibration helps the oil penetrate the rust.

Good luck getting them cut...The spec's are sooo tight that you can get one cut (maybe 2) on them before replacing them.
I tried it one weekend and ended up ordering new rotors all the way around.

Ya they are on there pretty good, and i dont wanna mess anything up. The reason i am trying to remove the rotor is because my inner rear left caliper wont come off. THis is due to my bent trailing arm(I cant even get an open ended wrench around the bolts). I rebuilt the outer portion of the caliper and hoped that it was the problem but it wasnt. so in order to rebuild it i have to either bend the trailing arm back or remove the rotor. I already tryed using a torch, sledgehammer, punch, but that didnt move the metal at all. That is why i am removing my rotor.
