guys,

i have looked long and hard for this info and still cant find it....

i have a 67 non power front disc brake car.

i have been told that the casting numbers which appear on the part itself do not match the part numbers. is this true?

i have looked in a chevy interchange manual and i have found that the p/n i need is a 5468813... but what does that mean about the casting number on the mc itself? could it have a different 54XXXX number?

in my assembly manual, the p/n is 5461705.

also, are the master cylinders for vettes and camaros the same?

i can get a 5455509 casting number 67 vette non power front disc mc, but cant verify if that same casting number would be for the 67 camaro....can you guys help?

i also have access to a 5480465 casting number that the guy swears is off a 67 non power front disc car... can any body verify that?

guys, i really need help here cause im going crazy....

if any of you guys have 67 disc brake non power car that you know is original and wouldnt mind getting that number for me, id appriciate it...

if you guys know where i can get one (besides a certain extremely rude rare parts dealer in michigan...sorry dennis), please let me know.

please help!!!!

thanks guys,

jeff

According to: "The definitive 67-68 Z/28 fact book" By Jerry MaNeish, the casting number: 5460346 is correct, and a J-52 option or JL8 option would have a small "WT" stamping on the small machined pad on the front of the master cyl. http://www.z28camaro.com/

but is that just for the Z cars?

i mean, i understand what youre saying cause option J52 is option J52 no matter what car you choose... but ive seen other "Z specific" parts that didnt make any sense either...

is the 346 good for both disc and drum?? if not, why would the WT distinction be made? or was WT used to signify power or non power?

and are there other castings that would be correct at the same time? or is 346 the ONLY correct mc?

thanks david and everyone else

I have a 67 non-power disc brake car with the correct, original master cyl. The car is being stored up in WA but I'll be going there tomorrow and I can get the casting # off it... It's a tall, 2 bail master with bleeders and looks NOTHING like the p. disc units..

i appriciate that panther!!

thanks!!

My RS is a J52 optioned car also. I had to order a vette mc. I kept the mc that was in the car, I'll look to see if it's even original to the car. I remember talking at lenght with the a guy at a good parts store here in redding. The discussion was having the proper piston size in the mc for our application. After cross referencing number after number, we came up with a vette mc as the only thing available that's correct.
GM having only built 205 67 camaros with this arrangement, I don't think a replacement part # was ever entered into the system. And I've found that, other than a few on this site, nobody has any info about the set-up.

so stevo

does the vette mc you have have the same casting number as the camaro mc?

the camaro mc manual j52 would have a smaller bore... 1 inch i think as opposed to the power 1.125"

if you have either the camaro or vette (or both) casting numbers, that would be very helpful

thanks guys!!

My son bought two 68 Z/28s twenty years ago both have been in storage since. We are trying to get one running. Both have different master cylinders one is a Delco Moraine with the 5460346 casting numbers on the right side. I am sure it is the correct master cylinder. The other I think is a Bendix. The casing numbers on the bottom of the master cylinder are 100-6 Made in USA
EIS 128 Does anyone know if this is the original master cylinder for this car. I need to have it resleeved. Both cars have power disc brakes in the front and drum brakes in the rear.

The Delco Moraine, 5460346, is the correct MC for a 68 Z/28. If you look on the half circle shaped machined pad at the front of the MC, you should find the letters "WT" stamped there.
Over the years, many of the "replacement" MC's sold, were Bendix units (I have a couple of them myself), but the one that came on the car when new was a Delco Moraine.

jks, I'll go down to the shop in a couple hrs. and I'll get the 2 #'s and post them.

kyvox,

ive been able to verify the 346 is correct for the Zs but my car is a SS 396. so would the 346 also be put on my car as well?

i am just trying to figure out if there would be any distinction between the cars even if the had the same brake setup (front disc/rear drum)

also, would the 346 be the standard for a power Z as well?

thanks

In the 1968 Chassis Srvice Manual (sorry, don't have a '67), there is a listing for Camaro with manual disc brakes. It is specified as a Delco Moraine with a "AD" code on the front. The letter code designates the displacement of the cylinder. It does not list part or casting number.
Wait to see what Stevo comes up with to see if this coinsides with what he has.
The Corvette MC will be different in that there is no check valve in the rear brake outlet for rear drum brakes.

Only 205 manual disc brake cars were built in 67? My 67 SS350 conv. has it originally and I have the sales invoice that has J52 and no PB...

panther,

did you make it up to your car? any casting number would be great... whenever you can

thanks man

jeff

Warren,
EIS is a company that was a major aftermarket brake component supplier.
That number 128 though is not in an old EIS catalog I have.
They show E71285 for 68, any chance there is a 5 after the 128?

OK, I got the numbers off of my master cyl...The casting # is:5488115 and the front half-moon pad is stamped "TA".

Oh man! I suck. ( no comments Clill, I know how you are. http://www.camaros.net/forum/biggrin.gif )
I just got back home, had the camaro out all day, just parked it at the shop, ( 3 miles away), saw this thread, and put a big palm print on my forehead.
Ahh, I'm sorry. I'll go check it out in the morning.
Color my face red. http://www.camaros.net/forum/redface.gif

Allright. I put the MC that was on the car back on it. The problem I thought I had wasn't the MC. The #'s on the car now are 29969. There's more stampings but I can't make them out at all.
The replacement MC says, EIS 123. That's the best I can tell. The 3 could be a 4, but sure looks more like a 3 than a 4. And there's also other stampings that are unreadable. I can't do anymore right now, I'm allready late leaving for oregon. 12 hr. drive. http://www.camaros.net/forum/eek.gif

so stevo

is that 969 mc the one that came on it originally? or is that the vette replacement?

and panther, youre sure that that 5488115 is original?

another guy on the other post has the same number as yours but he has power brakes...

or could that "TA" be the distinguishing mark between a power and non power disc brake car?

thanks guys for all your help...please let me know if you can answer these questions

thanks

I do not know for sure wether the master cyl. is the correct one or not. It is the one on my car and it has the regulator valve next to it. I also have the orig. paperwork for the car and it states J52, but not J50..

anyone else have this setup? a 67 manual front disc car from the factory?

just kinda bringing this up to the top again

please let me know if you have the original master cylinder

thanks

jeff

ok guys

i talked to jerry macneish about this and he did some checking...

according to him, a 67 camaro with non power front disc brakes master cylinder would be a casting 5460346 with a broadcast code "SA" stamped on the front.

He says that "WT" is the broadcast code for power disc brakes but is still the same casting number.

any of you guys have thoughts on this?

thanks for your help guys!!

I think the 346 was the short, fat master cyl...which I've never seen on a 67. I thought the 346 was for 68.

well,

i know for sure that the 346 was on a 67 Z... thats been documented a lot...but i wish i had one to be sure for myself http://www.camaros.net/forum/smile.gif

macneish is a solid guy... so even if hes not right, i think a 346 is going to be the closest thing to correct...

but let me know if you guys know different

David
Thanks for the information on the EIS master cylinder. The only numbers and letters on the master cylinder is 100-6 Made in USA EIS 128. They are located on the bottom of the master cylinder. The 8 is at the end on the flat area so there no room for a 5. So I still don't know if this the correct repacement for the D.M. 5460346. I should try to find an original master cylinder to rebuild.

Bringing this back to see how things went. Did you guy's find the right MC to work?

I have a 1968 Chassis Service Manual for Chev,Camaro and etc. This shows the Main Cylinder Code. Chevrolet & Chevelle Power-Disc SA= Secondary Piston Identification (2 rings or grooves.) Camaro Manual-Disc AD=Secondary Piston Identification (6 rings or grooves.)
I have a 68 Z/28 with Power Disc brakes. The casting number is 5460346 with the WT code. Secondary Piston Identification of (3 rings or grooves.) The number of rings or grooves show the displacement capabilities of the particlar cylinder. It says these ARE NOT interchangeable! The master cylinders should be replaced with the stamped two letters for each application.

eBay Motors item 1823725013 (Ends Apr-27-02 15:24:24 PDT ) - 67 - 68 Camaro Disk Master Cylinder - Rebuilt

does this mean this MC is a power unit. I'm looking for a non-power unit for my 67 ss 396

Ken King
67 SS/RS 396

The master cylinder on ebay is for a 68 Camaro with power front disc brakes. I may work on a 67 too. My service manual only covers the 68 Chevrolets.

It looks just like the manual MC on my car. (With disc brakes.)

If it helps this is what I got after cleaning it up on a wire wheel-casting number 54594S7 1" 10 D 7 on a 05d 4k car. Stamped AD(looks like the letters were stamped individually).

This thread went silent almost six years ago..... :)

Do you guys still need info on this master cylinder. My car has a complete factory setup with the manual disc brake setup. AD on front pad is correct and 1 " is correct size. The casting number is 5459467. The casting date is there also. I have one on the bench if you need pics.
This master cylinder is very hard to find. I have only seen 6 camaro's with this on it. 5 were l78 model camaros and one was a ss350 camaro but this one had different calipers on it and therefore can't say was correct.
All 67 models. 68 manual disk was not a option

I see in the CRG about front disc they only talk about one casting number for disc cars in 67. This is wrong.

This is a good topic! I thought I was the only whom found this confusing.

We just want the correct info out for all of us. This has been bugging me for many years. When i see wrong info and nobody seems to no, its crazy. The first thing people say when they havn't seen it before is it can't be right. They should say , i am not sure. I am not saying i have heard this from this site either.
