1965 Corvette Non Power Brake Master Cylinder Casting #618967

[Ted F.]

I've searched the archives regarding the subject. Didn't see anything really current, maybe I missed it. So, it is readily accepted that a brake master cylinder with a #618967 casting number is a replacement unit? A brake master cylinder with a casting #2225032 is the only one considered correct for a 1965 non power brake car? Externally they look identical. I have an older judging manual and am looking to see if there were any changes or updates. Thanks.

Ted,
If you feel your current master cylinder is non-rebuildable, these folks can take great care of you. In fact, you might want to send you current MC to them and see if they feel it can be rebuilt. Otherwise, use it as a core. Just a thought.

Here are a couple of pics. I recently painted the MC. Makes it a little hard to see casting numbers. Joe, based on all your contributions and great information you have posted over the years. A lot that was extremely helpful to me. If it is important to you, I'll take some thinner and remove the paint and try to get some better pics. Let me know if you want any other pics of it. Ted

Thanks Leif for the information - I'm getting to be pretty good friends with the individuals at Lone Star. LOL. Yesterday morning, I ordered a a casting# 2225032 MC with a date code that works for my car. Also, ordered new front and rear rubber brake hoses and caliper bleeders. Should have the parts early next week.

The bore on the MC that I removed from the car looked pretty good. After thinking about it and per advice from individuals on this forum, decided to not mess with it. I wasn't going to hone it, I was planning on lightly polishing the bore. In the end, I don't need any more problems with this car and I certainly don't want to mess with the brakes, especially since it is a single resevoir MC. Ted

No need, at all, to remove any paint. I was mainly interested in seeing if the configuration of the master cylinder was as it should be. From what I can see, it is. One of the reasons I asked is because I've seen that casting number (if it actually is a casting identification number) on some Ford master cylinders of the period. However, those master cylinders were otherwise configured somewhat different than yours. So, I don't know what the number means.

Ted,
Between the new MC and the new brake hoses, I think your problem will finally be resolved. Keep us informed.
