Gerald,

IMO, if it ain't broke don't fix it, the parts you install may not be as good as the parts removed..

Paul,

My m/c doesn't leak at all. I'm just trying to get it cleaned up along with a little preventive care.

Thanks

Jerry

Jerry, removing the m/c is an easy job, as you know, so if you delay this repair then it makes little difference as long as the m/c functions properly. If you decide that you want it rebuilt now, that's also an easy job. All of the vendors sell rebuild kits and it is very straightforward. I've done dozens of these on vintage cars (sometimes with a hone) and none of them have ever leaked. The one that I'm still in touch with that has the most miles on it I did 12 years ago (with a hone), and no leaks or failure.

This isn't like a transmision that's difficult to remove and you might want to bebuild it if you've got the car apart, even when it's working fine. If your m/c works fine, I would drain it, clean up the casting and lid, and flush it with a bench bleed. When it gets soft or starts leaking, then I would rebuild it or possibly send it out to be sleeved.

Yes, if the bore is perfect sleeving is absolutely not necessary. If any imperfections in the bore can be cleaned up with crocus cloth it's OK for re-use, too. However, if the bore requires honing to clean it up, the best plan is to have it sleeved. I have found that honed master cylinders just won't perform properly.

Joe, I'm very light with the hone. I use fine emory cloth to hit the blemishes, then lightly hone the bore to make everthing even and dress it. I've had very good luck with this. If there is pitting or ridges that are too large for my methods, then it has to be sent out or replaced.

Whitepost, Apple Hydraulics, SSBC in FL just to name three or two.

Dick:

Do you know if these folks will rebuild ANY GM master cylinder or only C1 & C2's ?

They do C1, C2, and C3 master cylinders. All of these are cast iron material. C4, C5, and C6 are aluminum material and I don't know if they sleeve these, or not. I don't see any fundamental reason why they could not but there may be one.

Peter, I cannot speak for John and Luke at SSBC, but Apple and Whitepost's main source of rebuilds comes from the antique car hobby. From the mid '20's when Chrysler introduced hydraulic brakes to the production auto, right on thru at lease the '80's. I do not know if they do stepped bore M/C's as they are very hard to machine.

Okay, Thank you, Dick & Joe.

Joe -

I don't know about Apple Hydraulics, but White Post brass-sleeved a full car set of priceless/irreplaceable early 60's Ferrari aluminum master cylinder and drum brake wheel cylinders for me over 30 years ago; you don't send parts like that to just anybody. They're still working fine, and have required no maintenance since. White Post has done at least a dozen master cylinders for me over the years.
