My brakes are leaking. I took them apart and they are the originals with no sleeves. There is some minor pitting. I can't seem to find anyone who will refurb my originals. Any reason why I shouldn't do one of the refurbished exchanges? Should I attempt to hone them?
Contact Ken at Lone Star Caliper. Send him your calipers and he will rebuild them with either lip seal or o-ring seals..your choice. https://lonestarcaliper.com/
That looks pretty shiny and silvery for a non-sleeved caliper. If they are indeed non-sleeved, I'd only go the route of having sleeves put into my calipers and not do an exchange. By sleeving your calipers you know it's a brand new sleeve. Rebuilt calipers have sleeves that have been subjected to all sorts of abuse and, more than likely, multiple rebuilds.
There are a couple other outfits besides Lone Star that do the sleeving — Apple Hydraulics and Corvette Stainless Steel Brakes. I'd seriously look into them over LS, due to poor quality of my last exchange set.
Lone Star will redo your calipers but they charge a "baby sitting " fee of $20 or more per caliper plus the rebuild charge if you can convince them to do them. If your sleeves are in doubt and possibly can't be rebuilt, then I would call CSSB in FL.
They sell the GM licensed repo calipers with the correct part numbers. You can buy lip seal or O-ringed calipers. Rebuilt calipers are still prone to leaking.

Without exception if that was me, I would be calling CSSB and asking them the questions. Correctly rebuilt calipers and proper brake maintenance will not leak. If QC isn't a concern, then call whoever you like.
White post is another option if CSSB is done. I have not used them, but they have been around a long time. I've never heard anything bad about them, maybe others here have some personal experience?

Thanks for all the great responses. I've just sent White post am email asking for a quote. I also sent an email to Muskegon Co. Found in a different post.

Muskegon is who I go to for brake parts but I wasn't aware they rebuild calipers in-house. If they reply that they do, please post it here.
I used White Post for a 67 mc rebuild. Nice work and reasonable. I've used Lone Star for rebuilding original calipers and Muskegon for exchange calipers. All 3 are reputable but consistent quality seems to vary by vendor.
Well, I decided to just buy the delco ones from CSSB. By the time I paid for shipping both ways for the refurb it would be a wash. CSSB says theirs are the correct castings with all the correct bolt heads so I guess I'm not out anything this way. Stamped part numbers might not match, not sure. Not sure if I care. I could always use my old bolts if I wanted to be picky.
is there a market for cores or should I just put them with all the other flotsam I have taken off the car?

Several years ago, I used Whitepost for a master cylinder. It turned out great. Based on that experience I recommended them to friends who were restoring 67 and 70 GTOs. In both cases the MC leaked after the rebuild. The 65 was sent back twice and still leaks.

I think you made the right choice, considering you have a '67. '65/'66 aren't reproduced so that makes the choices fewer for those who want to maintain originality.
Get a small brake hone and do it yourself. I did my own on my 65 and my dad's 78 this way. I had a sand roll flap assortment that fit perfect for finishing. Get new pistons designed for O-rings and be done with leaks forever. Did my 65 back in 2008, and still going strong. Flush fluid every 3-5 years.

I know you went with the new Delcos (good choice by the way), but in case someone else may be interested to know Muskegon doesn't rebuild calipers in house, they sell calipers rebuilt by Lonestar and have been for at least 25 years.
CSSB doesn't rebuild or sell rebuilt calipers, the only thing they sell are their new repro Delcos. Dealing with leaking calipers and unhappy customers just became to much of an issue for them so the only calipers they sell now are their own new Delco repro's.

Did you get the o-ring calipers or the lip seal one? If you got the o-ring one, post again after you've driven the car for a bit and let us know how it's working. I had a bad experience with o-ring conversion on my front calipers in 2004 and got snake bit by that.
I went with the o-ring. But these are new calipers and not a lip to o-ring conversion of an older set. It'll be a bit before it is on the road but I'll post an update when it is.
