I emailed Muskegon Brakes as I too need my calipers sleeved . White post quoted over $300 a caliper last year hence why I waited. Muskegon quoted cost of Camaro caliper build to be:

$179.95 per caliper with o-ring seals

or

$129.95 if they use lip seals. Turnaround time is approx 4 weeks.

That's bore, sleeve and test pressures. Survivor style no restoration (paint etc)

"Payment will be collected when they're done and ready to come back to you."

Was that for single piston or 4 piston calipers?

Edit to add: I just talked to Muskegon. They quoted me $179.95. If they send them to Lonestar, I wonder why Lonestar quoted me $219.95. I guess I'll be sending them to Muskegon.

4 piston.

I used Lonestar for my 70 LT-1 Corvette brakes. No issues.

That’s interesting, I’ll look into it. As long as you’re starting with a dry system, I’ve never had an issue with DOT5, other than bleeding it every 5 years or so on a preventative basis.

Mike Gibbons say dot 4 when he does brake parts.....Joe

The only advantage to Dot5 is it won't eat paint if you spill.

My 67 had DOT 5 in it since the early 1980s. The restoration was started in the late 70s and the original owner told me Dow Chemical gave him a couple gallons of DOT 5 to try. Amazingly, when I disassembled the calipers, wheel cylinders and master, all were spotlessly clean and attracted no rust, bores were all perfect as well. I have heard that this is another benefit of DOT 5.

I like Mike Gibbons. A great guy and easy to deal with. Had several parts done by him.

Absolutely true - DOT5 will not absorb water, so as long as you keep it sealed to prevent ingesting moisture, it should do a good job of preserving your hardware.
