1967 brake calipers

[Randy K.]

Does anyone know what casting numbers are on original front and rear brake calipers for 1967 427 car? Thanks in advance.

Re: 1967 brake calipers

they should all start with #545

Howard and Randy------

...except very early which used the 65-66 1st design calipers, the casting numbers beginning with "546".

Randy,

I think the calipers are the same for a 67 327. Here is what I took off my 67 327 standard brakes:

5452281 (Right Rear)
5452284 (Left Rear)
5452270 (Right Front)
5452273 (Left Front)

Could have mixed the boxes around but I remember taking them off and putting the new ones on, one at a time. Tried to find the numbers in the AIM but could not find the numbers listed. Can anyone verify whether I had the right ones. Very late 67.

Re: 1967 brake calipers

Thanks. I bought car in 1986, and this is what was on it. R.F. #5473798 - L.F. #5452273 - L.+ R. rear are both #5452284. I dont know if they were changed or not before i got the car. The reason i ask is that the right front started leaking. I went to advanced auto and got a replacement ( it's a rebuilt delco moraine ) so i can drive the car. If the leaker is right for the car i wont turn it in for the core charge.

Re: 1967 brake calipers

Jerry. I thought they would be the same too, but they ask if it was a small block or big block and they had differant numbers for both.

Re: 1967 brake calipers

Randy,

I learn something every day. I guess the whole wheel assembly with caliper attached were put on as one assembly, so there is no separate listing for the caliper.

Funny that I can't find a different assembly in the AIM under the 427 option.

Hope we both get an answer. Maybe Joe will chime in again.

Jerry, if i find out what the differance is i'll get back to you. Randy

Re: 1967 brake calipers

Jerry------

These are correct casting numbers for most 1967's. However, each caliper half has its own casting number, so there are 2 numbers per caliper assembly, inner an outer. Some of the castings are used for more than one position. However, the finished caliper half PART numbers (not found on the calipers) are different for each position, except front outers. Front outers are the same on either side.

Re: 1967 brake calipers

Randy------

There was no difference for the calipers used for big blocks and small blocks. Exactly the same units were used for both. Of course, one could have, say, a very early small blocks and that would have different caliper casting numbers than a late big block. But, that has nothing to do with the fact that a car is a small block or big block.

Re: 1967 brake calipers

Jerry------

The fronts were part of the front assembly. My recollection is that the rears were separate. However, any part number for the rears that is shown in the AIM will be the part number for the caliper ASSEMBLY. Such numbers will have no relationship to the casting numbers found on the caliper halves. By the way, the caliper ASSEMBLIES were never available in SERVICE from GM------only the caliper halves were available.

Re: 1967 brake calipers

Randy,

Here are numbers from a 427 - 67 coupe production number around 12,700. This was a one owner(CA)car, driven for 10 years and sat for 27 years.

Fronts(both sides): inner #5473795/outer #5473796

RR: inner #5452284/outer #5452281

LR: inner #5473806/outer #5473807

All the calipers have orignial paint dot markings on them, some blue, some white, along with some orignial black paint.

Re: 1967 brake calipers

Joe.. I did'nt think they were different for S.B. and B.B. cars but both advanced auto and napa ask which engine was in car. It's probably just the way it's listed in thier parts systems. Thanks, Randy

Re: 1967 brake calipers

Doug Thanks for your response. Randy

Re: 1967 brake calipers

Doug-----

I can virtually guarantee you that the caliper halves with the "547" prefix are NOT original to the car. I don't doubt that you accurately represent the history of the car. However, those caliper halves had to have been replaced sometime along the way. The "547" prefix caliper casting numbers didn't even exist in 1967. They came along about 1973-74. However, they were sold in SERVICE for all 67+ Corvette applications shortly after they began their use in PRODUCTION. It may well be that they were GM SERVICE caliper halves that were used to replace corroded bore calipers in the era prior to the advent of stainless steel lined calipers. Until that time, caliper half replacement was the ONLY method for servicing caliper halves. SERVICE caliper halves were painted black and may have other inspection marks, just like PRODUCTION.
