Brake Caliper Rebuild

[427.060]

Who rebuilds/restores brake calipers? I need the 4 piston calipers for my Beaumont rebuilt. I'm having a hard time just finding rebuild kits for the 4 piston ones.
Thank you, James

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.

That’s good info Bill.

The first time I used them was over 20 years ago for my 1968 Nova I had, which had 4 piston calipers. I didn’t have any issues and I owned it for approximately 8 years after having them rebuilt.

The second time was a few years ago for my Chevelle. They are single calipers…..with no issues.

At least in the past, White Post Restorations was the go to place in the eastern part of the country for this type of work. I don't have any recent experience with them, so cannot comment on their present reputation.

I was able to send mine out to the local NAPA store - I believe they use Cardone. They tagged them accordingly and returned my originals rebuilt and ready for paint/detailing.
