Does this looks right to you?
I've been installing C4 brakes on a C2 and even though there is no other way I see it could be mounted, to me it just doesn't look right.
I painted the calipers and brakets but when I installed the pads and the bracket onto the caliper unit, to me it looks like the 2 shoulders on the bracket would be grinding onto the disc before the pads do, the ones on the ouside I mean. Am I missing something? does the caliper or the bracket is supposed to slide away from the contact? The inside pad is fine, the bracket doesn't have any shoulders, just the outside.
It can't be backward, I'm sure of that.......
I wish I could post a picture but I guess I'm not allowed yet.
Thanks for any imput.

Clearly can't say for sure without a picture but here goes.
On at least 90+ C4's like mine (87 but 90 brakes) there is a "hoop" that is part of the main mount that sits on the outside and over laps the rotor and more or less frames the caliper. That I think is what you are talking about.
With the caliper itself slid outwards the pad will appear to be sunk inside this hoop and beyond contact with the rotor. Remember though, the hoop and the rotor are fixed, they cannot move back and forth, however the caliper can slide inwards and outwards within this assembly.
If when, your rotor is tight against the hub and the main mount is bolted down, there is no contact between the rotor and the 'hoop' then you are fine. When brakes are applied the first time, the caliper will center itself and draw up to the rotor. As the pad wears, the caliper slides further in towards the engine but the mount stays put.
If that isn't it, then pictures are required

Forgot to mention, on 90+ the rotors looks identical from front to rear, but are not. There is more offset in the hub on the fronts (laying flat, the fronts are higher).
Make sure you don't swap front to rear rotors or the mount probably will hit.

I added 3 pics on my album, click on my name, open up the album on the profile page and the first picture should tell the tale.
Thanks for the help!

That looks right. The black part is what I was calling the 'hoop' and if it isn't touching the rotor now, it never will. As the rotor wears it gets further away from it. The red part (caliper) can slide back and forth and will slide towards the engine as the pad wears down, maintaining contact.
Now it's hard to see, but if the black is rubbing the rotor now, you're in trouble, but if the rotor is flush (put 2 lug nuts on to suck it into the hub) and isn't hitting, it never will.
