Just re-bleed everything this weekend with same results. You can read the details in my current post. There are a couple people who think the pads are the problem and seem to understand the problem. My pads are stock from Auto Zone and maybe there no good for the vette. Going to look for some better pads this week.

Check out the post.

All you do is open the bleed valve and let it flow till it is solid fluid. Then shut, then do exactly as the service manual tells you to bleed. Powqer Bleeding should eliminate allot of the air quickly. ALso, once you are done, go out and make the ABS work, supposedly this will get all the air out of the ABS.

The manual says rf, rr, lr, lf in that order... after doing the master

My GM-SVC-M(1993) says RR/LR/RF/LF, page 5-13(Book 1) for the 93 after prime pipe is done(manual bleeding), then on page 5-14 same if you are power bleeding.
Some years are different, so checking your specific years may help. I know C5's are different.

I was having all kinds of weird brake problems, went to EM and they said the first thing to do was go have it "power flushed". I took it to Midas and watched to make sure they actually worked on it. Turns out, my brake pedal was intermittenly not releasing all the way, causing the brakes to drag. After the flush, the brakes work better then they ever have.

Awesome.
If it was intermittently releasing, did they fix it, tell you what was causing it?

Actually, I finally figured it out on the way to Midas. It was running fine, stopped at a light, then it started running crappy again, like the brakes were dragging. At the next light, I stopped, and with the the foot off the brake, the car did its usual non-creep, while it should have been creeping forward with no brakes. I stuck my foot under the pedal and pulled up. Voila! It started creeping! Since the flush, no more sticking pedal. Cost for flush was about $43.
