I began rebuilding my brake calipers today and I have an odd rear caliper. The odd one has:

1. Cad plating
2. Large adjustment screw (like the 914/6 rear caliper).
3. The same size piston as a 914/4 (so it's not a six caliper).
4. Dual bleeder screws
5. The piston adjusting mechanism is different.

The odd one definitely looks a lot newer so I'm guessing it's a rebuild from someone, but it's pretty different. Here, have some pictures.

This one shows the cad plating. The odd one is on the left.


Here is another shot of the cad plating and the dual bleeder screws.


Here is the back of the pistons. The odd one is on the left again. A normal one is on the right. Notice the adjuster screw size.


Any ideas? Any concerns?

Maybe it a Ferrari 308 rear caliper?

cheers,

I have two of these also, and two of the others. I think it is just the difference between early and late calipers.

Hi Mark,

the caliper with the two bleeding screws and larger adjustment screw is a later one.
Both calipers have been used for the 914/4 .

Both previous posts are perfectly correct. Just the differences between early and late 914/4 calipers.
Fully interchangeable. I do prefer the late ones myself.
