OK...whats the deal with removing thr rear discs to get to the parking brakes?
Both books I have show no picture but both tell of drilling out rivits.

Are these the flat flush heads I see between lugs?
Nothing in reassembley tells of replacing them after drilling them out, nor does it mention what size bit to use.

Dont want to just start drilling...

Is this a real pain in the butt...should I just bring it tio the Vette shop?
Any one do this?
Thanks :flag

yup drill em out. if they are still there means they havent been off before(usually). dont need to replace them as the caliper holds the rotor in place anyway.
just drill the heads off them.
good luck, pretty easy job.

Take your time don't get pissed I am telling you this because the rear brakes will get you a little crazy. Drilling the rivets out is the easy part!!!! taking the calipers off is no fun as well. If you take parts off the rear parking brake be prepared to take some time relax and put the new stuff on there. I ordered a parking brake kit it makes everything go a little easier when the parts are new.

...so the rotors will come off when the rivist are history....
No special tools?

It would be wise before drilling to mark the position of the rotor in relation to the spindle. This will minimize runout and reduce the possibility of air pumping into your calipers. Mark a stud then mark the hole that the stud passed through in the rotor.

Like was posted earlier, mark the rotor and a lug to replace the caliper back in the same orientation. The parking brake assembly is not that complicated but there is zero room to work on it. Reassembly can be frustrating. Atleast it is for me. Otherwise it is just your basic drum brake under the rotor. There is a decent instruction from zips. I think you can get it at corvettefaq site. Good luck.

The biggest PITA that I found was getting the post back through the spring and clips. Have good light. Take a comfortable seat, etc. It is a real puzzle, especially the sides where you can't get behind the post to hold it out. By the time I got to side 2 I was almost nuts but I figured out that I could tie fishing line to the post and pull it out through the other parts. This helped allot. Also I made a fork so I could turn the cap/clip after I had grabbed the barb on the post with some needle nose pliers. Have fun. The good news is that it shouldn't have to be rebuilt for another 20 years. :banghead:

Of course the parking brake couldn't begin squeeling when it was in for the 700R4 conversion. As soon as I began to enjoy the new tranny the lil sucker began the squeel from the right rear. Changes pitch when I pull the parking brake a bit. It's the original set up....bought the car from my hi school friends Mother about 5 years back, the Original owner... Had the Original tires too.

The weather is so nice lately....gotta fix it soon.
Thanks everyone

Another thing to keep in mind is that if the rotors have not been off before it will be a PITA. You will probably need to use penetrating lubricant and let it work over night.
