Ron's comment about putting the front calipers on the wrong side reminded me of similar problem — one I've seen on aftermarket replacements (twice). This may seem pretty far out, but it happens...

This is when rebuilt calipers are reassembled wrong. Girling puts a "dimple" on each caliper half, at the top ,on each side of the mating joint.

It''s possible, for example, to assemble a Left outer half to an inverted Right inner half, and it will look fine. But be impossible to bleed properly.

The tip off isn't obvious, but the match-up dimples won't be side-by-side on the same end of the caliper. One dimple will be on top of one half, the other on the bottom of the other half.

I have two of these in my garage right now. They came from a junker, but were nearly new-looking, so I grabbed them. Now I'm stuck with them.
