1967 brake caliper question

[Timothy B.]

I am thinking about replacing the V/B calipers on my early 67 with correct first design castings and pistons with insulators.

I want to be sure what casting #'s to ask for so I get this right the first time. Can someone with a early 67 confirm #'s for me. In archives the cast # 5465952 is mentioned for front, is this the same for all halves in the front?

What is the rear caliper casting # for this September 23, 1966 built 67.

Also, I would appreciate comments on oring style pistons compared to the original style.

I appreciate all suggestions and help..

Tim,
Figured I would tag on to your post. Have a Jan. build 67 small block car with the right front caliper starting to leak. I am going to take the TDB advice and send both front calipers out to LoneStar for rebuild. I believe they are original to the 35k mile car. From the archives I know there is a 1st design and 2nd design. Where was the transition vin wise? Iwould like to double check the casting numbers and see if it is reasonable to keep mine.

John,

From what I have read first design calipers have 5465---. I just want to be sure before I call.

If you think they are originals to the car have them rebuild.

65-E67 caliper casting numbers were as follows:

front: 5465952 and 5465954

rear: 5465902 and 5465905

Thanks Joe,

That's what I read in archives.

If I understand this correctly, there could be any combination of these depending on how they were machined so for example on the front there could be four halves 5465952 or four halves 5465954.

I don't know how expensive the first design pistons are and I am thinking oring pistons may be easier to maintain.. your thoughts..

The fronts would have used BOTH casting numbers. One of them was used for both outside caliper halves and the other was used for the inside caliper halves. I don't recall which is which, though. The same thing was true for the rears.

The 1st design pistons are expensive---about 25 bucks each. I think you will find o-ring pistons satisfactory for street operation. One thing to keep in mind though is this: the 1st design calipers have cast-in piston guides. If these have previously been machined out or if you have them machined out, then you cannot use 1st design pistons. In this case, you must use 2nd design pistons or o-ring pistons. I know of no o-ring pistons for use with 1st design calipers with cast-in piston guides.

Thanks Joe,

I understand about the casting #'s now. I am very curious about the changeover from first to second design.

Are there any members with first design calipers that can help narrow the approx serial # change from first to second design..
