Brandon, I'm used to seeing a number cast into the bottom of the master. If there is none I wonder if its an aftermarket part?

drum brakes, manual and I believe power too. at least 69 and 70.

is it for sale? is that an original cap in nice shape?

brandon reynolds

Yes and yes. This is a super clean master cylinder inside and out.

70Post

How much?

That is an Original DELCO Master Cylinder -- in all likelihood -- because of the bleeder screws -- though it is true that the aftermarket had them in that design for a little while....


It IS CLEAR that it is a 4 wheel DRUM BRAKE Master Cylinder, for sure, by the illustration ..... 1967 - 1972 circa.....


The casting number (on the bottom) will definitely tell us EXACTLY what it is -- and if you want that information, give me the casting number, and I WILL tell you what it is...............

Heres a pic of the bottom. Definetly a gm part. My research says 68-72 manual and power drum. Let me know what you think. Thanks brandon

CT is factory stamping for 1967-70.

That symbol before the # --- IS --- the DELCO MORAINE symbol (the two
arcs) -- so this --- IS --- an O.E.M. Master Cylinder....


I will investigate the 5460465 -- and tell you what it is....

That 5460 465 IS the DELCO # and design -- with the bleeder screws for
1967 - 1970 Oldsmobile Cutlass / 442 and Chevelle / El Camino with
4 wheel drum brakes system.....
The fact that it is an Original G M with the bleeder screws should make it
more desireable to someone who is doing a "concourse" restoration on such
a vehicle.....
The fact that it is 4 wheel drum doesn't make it the BIG BUCKS Master Cylinder -- because of what it is -- and what it isn't.....
But it still is the Bigger Bucks Master Cylinder because of brand and design....
Hope this answers your questions --- I may have a kit to rebuild it.....
Any questions or comments -- Call me -- Craig -- 516 - 485 - 1935 ....

Do you have a means of decoding other Olds master cylinders?

I've been active in the antique parts world for over 45 years -- and, of course, have some beautiful old catalogs and interchanges....
Much of what Ihave --- you are NOT getting on the internet -- despite how much internet access you have -- and how much internet savvy you have.


Remember -- the computer is only as good as the guy who programmed it -- and if their information is WRONG -- you get fed WRONG info......


Fox example, do you know how many things rock auto has listed inaccurately??????? And some people follow it as if it was gospel......
I could tell youstories aboutwhat I've seen and heard at car shows -- in regard to the literally STUPID things that happened on the computer....

The "CT" stamp code is widely used by all GM divisions. It would be correct for 1971-72 also. Another code you will find for drum brake cars is "DP", although not as common. Don I can help you decode some other Master Cylinders. By the way, some of the inspectors guides depending on the printing date are incorrect with there information.

junior supercar

yep, just like EA in 69 for disc brakes and EB in 70 for disc brakes. So don't limit yourself to just Olds, other GM divisions use the same thing.
