These are my new Remanufactured Advance Auto calipers. They are Delco Moraine and cost $42.50 each with a lifetime warranty. I couldn't rebuild my old ones for that.....The pistons were corroded and the bores were pitted. Not sure if they were even SS sleeved. The core charge was 45.00 each. Should I keep the old calipers or just return them for 45 bucks? The car is 1970 coupe with original 350/300 engine, M21 trans and 4.11 rear.

you could use them as door stops or paper hold downs. I still kept my originals don't know why they weren't that bad maybe im hoping to run in to a guy with a 69/70 impala who wants to convert to disk brakes and help him out but they are just chilling in a box
Wow those are really bad... I would try to use them as cores.... they are no good really even as rebuild able cores so they may no accept them.... funny how advances prices are so much cheaper for you? Advance now sells "new" calipers for our cars too....sold under the weaver name I believe... they were still under $100.... likely the same china one I got. Funny thing is mine does not say made in china anywhere on the unit or box?

what makes them "no good as cores"? a trip to the sand blaster, some SS sleeves, new pistons, seals, some silver paint and they will look just like yours...

Well from other threads I've read here about caliper core credit being rejected a lot of these rebuild companies are pretty picky on core condition and the amount of surface removal and possible blockage of the fluid passages makes a lot more work involved in refurbing those.
Those look like they were sitting in the dirt for a while and even after blasting the surface will be pretty pitted. Not something I would pass on to another corvette owner..

The employees at Advance or Autozone will hardly take notice of the condition of the cores.

The guy I had opened and inspected it before doing my return.... he also mentioned it may take a bit before the core fee was credited to my card... But yeah I guess if that's true its an advantage to buying from the local auto store rather than dealing with the corvette venders which are less forgiving about core condition. Unless the couple testimonials Here were not disclosing the whole story.
that the factory never used o rings, they should have. I've found most of the good rebuild kits have aluminum pistons with some type of corosion protection. those cast iron calipers can corrode a lot before they are unusable. im waiting for the chinese to start casting them in aluminum, wouldn't that be nice ! im not holding my breath though.
Advance would not even look in the box before refunding the core. Believe it or not the rears looked just as bad as these. A few minutes on the wire wheel and I had them looking like brand new except the bores where still pitted even after trying to clean them up with my die grinder and fine medium grit sandpaper wheel. The online price for them is 64.99 but Advance has been running a special of 15% off and a 25.00 gift card good on your next purchase so it works out to be around 45 bucks each....can't beat that for and they are guaranteed for life!! I don't think I would like the Chinese calipers. The only reason I went this route was the fact that they were Delco castings and look original. As mentioned earlier...does it make sense to keep the cores as I have a numbers matching car??

Duntov motors mentions on their website that the chinese calipers are very porous and can eventually leak through the casting but you guys don't seem to have had that problem. I agree that I would go with auto zone, advanced etc only if they were OEM castings. CHANGE the brake fluid periodically-every 2-3 years even 4 years-and you will not have any issues with aluminum pistons corroding. Like I said earlier, my VBP calipers with OEM lip seals, NOT o-ring seals that I put on my 78 in 1985 (that is correct 1985!) have never leaked and work perfectly. Nothing like real world experience over many years.

The pics I posted were of a "rebuilt" caliper from advance which I don't believe to be rebuilt at all but rather a new one.... everything looked very new including the bright freshly looking machined surfaces and upgraded stainless pistons.I don't know where it was made but its unlikely that it was the US... the caliper I replaced was also a rebuilt from advance and was a delco moraine rebuilt unit...
They are Chinese for sure, as most Auto Part Store items are these days. Price out a set of rebuilt units from Lonestar, these WILL be Delco-Moraine castings. Get the O-Ring seals if your car sits over the winter, replace your brake fluid every third summer (really easy with a $60 Motive Bleeder). Make sure to set your rotor runout to minimize cavitation. Organic/Asbestos pads to minimize rotor wear......and consider the brake issue taken care of.
Does anyone know if the Delco-Moraine remans from Autozone / Advance are O-ring or lip seal?
why is this so difficult for people to understand.... I got the reman from advance and they give you whatever they have on hand... last time a delco unit this time they gave me a new china unit and told me it was a reman...
autozone sells cardone rebuilt covette calipers according to their site but when I got my master cylinder there is was not cardone but rather the same "OEM" brandname that was on the box my china caliper from advance sold me... I feel I got a good caliper since the pistons were stainless but I doubt the used orings and not the lip seals they also sell in a kit for $10 (I bought 2 rear lip seal kits from autozone for $10 each and rebuilt my rear calipers in under an hour... very easy and I recommend doing this if you have stainless sleeved calipers...

can you please show me where it says you got stainless steel pistons?

It doesn't "say" it anywhere but I work with different metals everyday and I know its not aluminum or an alloy. Also I checked it with a magnet and it had a very low reaction to a magnet.

I just find that sentence funny. Like the factory calipers didn't leak?? I've owned my Corvettes for decades now and changing calipers more often than motor oil.

I think that Duntov means that the castings, not the piston/seals, are porous implying the casting can leak.
As stated earlier, I have a full set of VBP SS calipers with regular lip seals on my 78 since 1985 and they have never leaked-that would be 29 years and counting. If the total brake system is good working condition and the owner changes the brake fluid often-every 3-4 years-complete flush, the SS calipers should last a LONG time with no issues. If people are changing calipers "more often than motor oil" than something is very wrong with the calipers, brake system, rotor runout, etc.
