C2 identifing a 1966 power brakes master cylender

[Larry S.]

Hello to all its been a while since I have needed your help.I have just finally purchased a correct master cylender for my 1966 corvette with power brakes.
(I should get it on friday and have untill tuesday to inspect it and make a decition if I want it or not)I was warned (by a couple of the used parts vendors at corvettes of carlilse)that there are a few remade/recast units out there being passed as the original GM part #5467084 with screw on caps and 1/4" ports .I am trying to find out what the difference between the real one and the one that was recast.I am paying a HIGH price for mine and want to know how to positively identify it.
As always your help and advice is greatly apreciated.
Thank You Larry Savino

No, the gold plated ones cost even more! The deal here is that 65-66 Corvette power brake master cylinders are rather "rare birds". This style master cylinder was only used in Corvettes and only for those 2 model years and only for those Corvettes equipped with power brakes. Plus, although the castings are the same for both years, there are slight machining differences in the 2 years.

The original GM SERVICE master cylinders have been discontinued for over 25 years and, as far as I know, no other manufacturer besides Delco ever made SERVICE replacements.

It is possible to use the 67-82 style master cylinder for a replacement, but the configuration differences between these and the 65-66 style are major. It wouldn't even fool a totally blind judge.

i wonder how he came up with a odd price like that,maybe he took the orignal price any multiplied by the number of years old it is. nothing supprises me after i heard of a corvette owner in my area paying $15,000 for 5 orignal tires for his 67.

Thank You
A fellow from this site has one on his shelf and we are going to compare them via e mail. I have looked for almost two years for one and finally gave in and decided I will pay what the going price is.I did contact the fellow advertizing the $715.00 around august and at that time none were in stock.I had placed an order with a vendor on monday he had one and I purchased it.I have updated my profile on this site if anybody wants to read it.I will also update a link to a picture of my car as it is today.

Sometimes, I think that "off-round" prices for certain Corvette items, especially high-priced ones, are designed to make folks think that there is a "rational" basis for them and that they are "firm prices". If someone asks, say $700, for an item, many folks think that's an "asking price" and the starting point for negotiation. If they ask, say $717.34, then many folks assume that's the price----period.

[Clem Z.]

the price

that is like the story, a women goes to her butcher shop and ask how much is the steak, the butcher says $6.95 per pound. the women says the shop across the steet only wants $5.95 a pound but he does not have any. the butcher then says when we do not have any we only charge #5.95 a pound also. maybe the same thing applys here.

Re: C2 identifing a 1966 power brakes master cylen

Ok I have the master cylender in my hand no and it has what seems to be original white platstic screw in cap's that definatley look old! but they do not fit the openings in the top of the master cylender theu fit right in with out screwing them in .I would assume they are aproximatley 1/8" to small in diameter.what other master cylender has screw in plastic caps? My first assumtion is the caps are correct and the master cylender is a repop with the wrong diameter holes machined into them for the screw on caps.I HOPE I AM WRONG and I just have the wrong caps and this is the correct master cylender I am awaiting on a the email from A ncrs member who has a real one on his shelf so we can compare.

Any advice or input is greatley needed and apreciated

Thanks again LARRY SAVINO

Re: C2 identifing a 1966 power brakes master cylen

Thank You Mr. Coenen for the offer but I am afraid to go into a vendors wharehouse (too many good things to walk out with like a kid in a candy store)A sincere Thanks for the offer.

I was thinking about you last night.Your catalog is the most thorough catalog I have ever seen and use it often as a refrence when reassembling my car from your drawing's.

Re: C2 identifing a 1966 power brakes master cylen

Larry- Another master cylinder that uses a similar plastic cap is one for a
62 Vette. The diameter of the opening on a "022" MC is 1.25 inches with the wording "use delco brake fluid". I had a 66 w. power brakes 15 years ago and if
memory serves me right, the cap on that one was much larger than the 62 cap.

Re: C2 identifing a 1966 power brakes master cylen

Donald thank you I will measure my caps when I get home and I hope thet measure the same size as you have mentioned.
