Thanks for reading this post. First of all, I am new to 914 repair, but have mechanical experience.
I am rebuilding rear calipers on a friends 1975 914. The pads look like they have a lot of life still and I was planning on reusing them. But something looks wrong to me. This may be due to me not being a "914" guy. Each pad has on the back side a fairly thick shim, probably close to 1/8" thick. The odd part is the pad is only on half of the pad, so it seems to me like the piston would not push squarely on the pad. So my question is: is there a problem with these pads or is it some 914 thing that I don't understand.
My only explanation is that part of the shim has come off of each pad, but that sounds unlikely. I have no way of finding out who installed these pads.
I have attached a picture of the back of the pad. You can see the raised part on the right side and the half circle witness mark on the raised part. This looks really wrong go me. Both pads on the one I have apart look like this. I have not opened up the other side yet.
Help please,
Thank you,
