Brake Caliper Rebuild

[69 Post Sedan]

I’ve sent mine to Muskegon Brake in Michigan. They do wonderful work.

Muskegon Brake sublets 4 piston caliper sleeve/rebuild to Lonestar Caliper. Lonestar says they are wholesale only.

I have had two pairs of '67 Chevelle 4 piston calipers done by them, both had leaks on the driver's side. The first was resolved with the first return. the second was returned three times, each time the leak was a different place.
The routine was, I call Muskegon, send them the leaker, a couple weeks later Lonestar ships directly back to me.

A problem with these Chevelle 4 piston calipers is lip seals, no O-ring seals are available (2 1/16" IIRC) whereas Corvettes use O-ring seals. Do not use DOT 5 fluid!

Just my experience, I have three NOS HURST/AIRHEART kits is you are interested. - Bill W

FWIW - I had my Z/28 calipers resleeved maybe 15 years ago, by Vette Brakes, and have used DOT5 in that car ever since with no problems.

Memory jogged Tony, Vette Brakes did my Corvette calipers in 1982. Zero issues in 40 years.

Chemistry is not my strong suit, I have been told by Muskegon that the old formula DOT 5 has not been available for several years and that current DOT 5 is not compatible with the brake parts in our old cars.
Lonestar, and I believe White Post and Karps warranty is voided with DOT 5.

If this is incorrect, please set me straight! - Bill W

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.

I have used Lone Star exclusively for 30+ years, and never a problem. I'm currently restoring a 1969 350/350 A/C Corvette Roadster and a 1976 Corvette Coupe and received exchange Calipers for both projects. Everything looks as it should. The kicker is there was a note inside all calipers that if anything other that Dot 3 brake fluid was used, the warranty is VOID.

Back in the late 1980's all we ever used was Dot 5 silicone brake fluid because it would never stain the paint. But that was then, and this is now. Bill
