seals for brake master cylinder

Old 2004 info from a thread here:

"Master Cylinder Seals: These are 7/8" Alfa Romeo rear wheel cylinder seals (3 required) and are available under a part # 4115452 from GT Car Parts in Phoenix, 623-780-2200 (Dave). The rear seal is not available as far as I know, but it looks to be a wiper seal, so if you have a problem, this seal isn't going to save anything anyway.....so reuse it."

You might also consider a moving up to 1" diameter master cylinder. Wilkenson suggested that to my, saying that cures most the issues with a stock brake system. I haven't done that yet but when I go through my brakes in the next 6 months I will be investigating that.

If I get desperate enough I will use the new one that is available through the vendors. I have one- though they call it a reproduction, it will not fool anyone, there are many differences, including the reservoir being backward, the size, the wording, etc.

I spoke with someone briefly at GT Car Parts- they asked for the bore (I believe it is 23?), they now have "rebuild kits" available in different sizes. I will get back with them tomorrow.
