I'm working on a CRG metallic brake report for the J56 and J65 brake packages used iin 1967. As many of you may know, those metallic brake packages were discontinued after the '67 model year. The finned brake drums used in '68 seem to be a lower cost alternative to the earlier packages and so I would like to understand which models received the finned front brake drums in 1968 and which models did not. So far, it looks like the SS models and L30/M20 models have the finned drums as standard equipment but I'm not sure about other models. I would appreciate any input on this so I can have a high degree of confidence in the accuracy of the report. My understanding is the rear drums were not finned for any model of Camaro in '68. If I'm wrong about that, please let me know.
Thanks,
-Jon

My best recollection of a 68 SS I had a long time ago was, the front drums were finned and the rear ones were not.
-
Although my car is a 1969 Base RS Coupe (01C Norwood) and not a 1968, it does have drum brakes. Drums in the front are finned; drums in the rear are non finned. So at least by the time Jan 1969 had rolled around, finned drums were being used on base cars as well.
-
As another data point, my 68 L30/M20 has finned front drums and non-finned rear drums.
-
Thanks guys for the data so far. I'd appreciate hearing from others, especially '68 owners with 327 and 6 cylinder cars.

My 04A 68 RS/SS 396 had finned front & non finned rear.
-
I used to own a 68 camaro, power drum brakes with 327, 2bbl, and air. It had front finned drums also. I still have the trim tag info if you need it. I bought the car in 1980 and there were several owners before I got it, but it was complete just needing a new motor.

06A SS/RS, original drums, front finned, rear without fins.

Thanks for the responses. Still looking for brake drum data, especially for the '68 327 2-barrels and 6-cylinder cars.
Thanks,

My 68 base 327 2 barrel has non finned, non power fronts. Both my 67's (1 base 327 2 barrel, 1 RS 327 2- barrel) are non-finned non power. My brother's 68 SS/RS 396 however has power finned front.

68 07E L-30/Glide....Non finned front and rear....

Jon, my '68 was a base 327 car, and it came with finned drums front and rear with manual brakes. In fact, it still has the original drums on it. I got the car in 1983, so it's unlikely anyone had added the finned rear drums because of the extra cost. I don't know if it was a 2-barrel car because the original engine had been replaced, but it had a factory manual transmission and a monoleaf 10-bolt if that helps.

Yes, if you could post the tag info, that would be helpful, esp the build date.
Others - please include the build date in your posts. That will help to see if there's a trend.
Thanks!!

Mine is a very early Norwood car going by the VIN. Hope this helps.
-
I've got an 04D '68 Base 'Vert. It was originally equipped with a six cylinder.
Drums are non-finned, front & back.
Sorry, I'm so late with info. Don't usually read the research topics.
Thought I'd chime in with info, anyway.

qwertyme77 - what was the builddate of your car? By air, you mean AC, right?
T-Bone - AC on your car? What's the complete build date?
kcracing - do you know what engine originally was in your car?
Thanks guys!

The car I referred to early on was an ss 350. I don't have any of the data on it but I do have a bad picture of the cowl tag. Did I send that to you before to try and read it?
-
I don't recall, but it sounds like I don't need it. :)

I think I'd need a CIA computer to read it anyway.

Hello, I see you don't have a lot of 67's here, so I'll chime in. My 11A LOS built Coupe has the LF7 Engine and Manual Brakes, it has unfinned Drums both front and rear.
-
The front drums that were on my 68 RS are non-finned. The rears were finned but I don't believe they are original, they don't fit that well. The car is a 12D LOS. 327 2bbl Powerglide. Manual drum brakes and manual steering and no other significant optons. I can post the casting numbers if need be. Are there date codes on drums? Hope this helps.

My 1968 RS has unfinned drums front and rear, car is an 07E, I believe to have been built in the last week of production but I do not know that for sure the serial number is within of the last 300 of the end. I don't know if this helps. Darrell D

Darrell,
That's a really late 68. Does it have the 210 hp or the 275 hp version of the 327?

Same question: Does it have the 210 hp or the 275 hp version of the 327?
Are you sure on the finned rears?
Thanks!

My '68 RS was built 02D, 230 six with 3 speed manual. Non-finned drums front and rear. This is my first post on here...moving here from the Team Camaro website because I'm more of a purist. Is there a forum regarding glass?

Kurt, my drums are both unfinned front and rear, 11A built 67 LF7 with Powerglide.

Can anyone explain the differences in the brake shoe sets used with the finned drum as opposed to the non-finned drum? GM specifies a different part number. Thanks, Joe.
