Clean unit. Rectangular with bleeder valves. Casting number 5470409, "EB" on front machined surface. Prefer date for late 1969 built car, i.e. high 200's to low 300's.

Thanks.

I have one that is 318 but can't let it go yet. I need to take the original one on my car apart and rebuild it first. With my luck, If i let this one go I would find that mine is bad. It may be a couple weeks till I know so if someone else has one jump in.

briane

Thanks for sharing that, please keep me in mind as 318 would be a good date for me. I'd be interested in knowing how many people here find they require a sleeving of their master cylinder when they rebuild. In my limited experience I have not had to do so. Good luck.

I have 3 or 4 of the originals, I'll try to check the numbers on them this weekend.

I still have some left,but need to check the dates.These are from 70 disc brake cars. W30's & W31's.

briane

Thanks guys, I'll keep my fingers crossed. Looking for a very clean one (or two) for a restoration.

Brian,
Here are a couple I've found so far. The last number in the date code is hard to read on both of them, but they both look like 33? numbers to me?
Take a look & let me know?

I see what you mean--hard to read. The one that's painted might be 138? Are the "EB" stamps on the front machined surface legible?

Thanks.

Braine, I dont know if you need one but I have an NOS in the bag master cylinder cover. Dave

briane

I'm in good shape for cover, I found a couple of new ones years ago. Thanks very much Dave.

I'm still looking for a master cylinder, however.

Brian

507OLDS

Hopefully,I can look at mine today.

briane

Thanks 507OLDS.

Dave I should have asked what part number cover you have.

Brian

Briane, its in a Delco Remy sealed bag and there was a paper on it with the part # and all the information I cant find it but it its for a 70 because back when I had the car I was buying nothing but NOS for it.

507OLDS

I haven't gotten my parts out yet,but I found some notes from last time I did this,and the dates I have written are 195,285,and 314. Now I just need to see if I still have them.
5470409. With 1 1/8 cast into them designating bore size.

507OLDS

Ok, I just checked,but no go. I have the 195 and another one I can't read. Sorry about that.

briane

Thanks for checking for me. Eventually one will surface (I hope).

Brian

I hope to take mine apart today or tomorrow and see what it looks like. If I don't get side tracked with other stuff... If mine is good I will let my extra one go.

briane

I'll cross my fingers that you do have two good ones.

What are you using for a rebuild kit? I have a bunch of NOS kits for this casting when it's used with a power booster but I think it's a different kit for manual disc brakes. I have to check.

Thanks.
