My 77 calipers leak. Rebuild or replace?
I know other makes it can be about the same price.

IF your calipers have been replaced, they will probably be sleeved. If not, then they probably need to be. Unless you have an attachment to them, is way easier to just get remans from your local parts store.
They're pretty easy to rebuild yourself with just a seal kit, but if the bores are pitted they'll need sleeves anyway.

In the spring of 2012 I bought 2 front calipers from my local NAPA. Since then I have replaced the left one twice and the right one three times. They simply start leaking at the seals. I have great doubts about the big-box store remans. I bought o-ring style from CSSB through Ecklers. You can buy direct. I would consider them or Lonestar.

I'm guessing replace all 4. Also, what does it mean when the rear resivore empties?

Any caliper rebuilt in the past 5 years is a gamble,

and it "doesn't matter which brand"

here is my pile of lonestar calipers. Total 9.

I now have wildwood D8-4 , still no long term report since these are now on year 3. I use my car for track days so the rebuilds don't take the heat and the seals fail in 1-2 years. If you had calipers from 12 years ago most of them are still working fine. Find a store that provides the best warranty and plan to do the work your self. You will be replacing them again. Or try to rebuilding your self. Same amount of work and less money to spend if it fails.

I installed replacement calipers from Vette Brakes about 25 years ago when I first got the car. Replaced them with another set from Vette Brakes about five years ago when they started leaking. Unfortunately I understand Vette Brakes isn't the company they used to be. Still, I think if you buy good stainless steel sleeved calipers from a good company that specializes in Corvettes, you should expect good life, and if they start to leak, you can rebuild them. I would have rebuilt mine, but I was in a hurry to get the car ready for a road trip art the time. FWIW I'm not convinced O-ring calipers are a good idea. There's nothing wrong with the original design.

You need to bleed the master cylinder after you repair all the leaks.

You can try this method to bleed the MC while it is still on the car. Worked great when I change my MC.

Rebuild?

I replaced my rear calipers with the NAPA units last summer cheaper than I could buy the rebuild kits for. No brainer

That makes 2 of us. The local AutoZone works out great for Delco Moraine Corvette calipers. There's so many A-Z's out there that if 1 don't have it the other store 15 minutes away does. Throw in the warranty and savings on shipping and its a great deal.

I got 4 reman ones at Auto Zone with a lifetime warranty so if they start leaking I just take them back.

Replaced the right rear and left front. The two that were leaking. Autozone calipers.
My vacuum bleeder kept suckling air bubbles. So I got an assistant to pump the brakes. Works now.
