Recommendation for master cylinder resto

[Michael L.]

Guys,

Looking for someone to restore my master cylinder. Anyone have any recommendations?

Also, I'm thinking of what to do with the MC cover and bales. I believe it is the original, but the chrome has flaked off and it's pretty rusty. I think I can reuse it but not sure if I should blast it or if I should send it to the plater to be stripped chemically. What do you think?

There are quite a few folks out there that can rebuild your master cylinder, Lonestar is one. It will almost certainly require brass or stainless steel sleeving. NEVER go with simply honing a master cylinder bore----it has to be either PERFECT, as is or it needs to be sleeved.

No original master cylinder cover or bales were EVER originally chromed. If any of yours are so-finished, it was done post-factory. Chemical stripping is the best but if the cover has suffered any corrosion-induced roughness or pitting, the refinished cover is not going to appear exactly as it originally did.

Thanks Joe. I will send it out to be stripped and if there is any damage I will see if I can source a replacement. Are there good quality repros out there?

Lonestar in Texas dose a great job . No chrome was ever used on caps and bales.

Actually Joe, can you tell me if there is any date coding on the MC so I can check and ensure that this is the original one. If the cover and bales have been replaced/chromed it tells me someone may have changed out the MC itself. If it's not the original I can try and source a date coded one.

Mike, the C3 date codes are on the front line fitting boss, you may need to get some glasses or magnifier glass, print is very small. I believe the its a Julian date.

Ed,

So for a Sept 69 build car what would I expect to see on the date? Up to 2-3 mo before that? up to 6 mo?

Mike, I really do not believe that logic plays a roll with dates in every case. I would say look at the date first, and see what you come up with ,even most judges will say a few months is okay.

Below are some photos of a known original master cylinder from a known original, original owner 1969 Corvette with a body build date of September 13, 1969.





The Julian date of "9253" denotes September 10, 1969.

Re: Recommendation for master cylinder resto

OK if they were never chromed, what is the original finish for the bales and covers?

[Edward J.]

Re: Recommendation for master cylinder resto

Mike, Joe's pictures show the colors, the cover was a Gold Dichromate, bails had some kind of coating, but not sure if they were just natural, as they did not seem to rust easily.
