I don't think it was at all clear that was what occurred. And I've been amazed at the number of high end bikes on eBay pictured with the shoes backwards. Of course, it's a little harder to do this with Campy, or other shoes with integrated wheel guides, since it is pretty obvious if you have installed the shoe upside down. But if you switch a shoe right to left or front to back, you can still get the open end to the front. Some Campy designs, like the aforementioned DO adjustors, don't cater to common sense either.

If the pads slid out, the brake shoes were installed backwards - that can happen on most classic brakes, including Campy.

Jerry, Read the whole thread and hopefully you will realize that he's talking about the mounting shaft of the MAFAC pad slipping in the eye bolt allowing the whole brake shoe to slide outboard, resulting in increased lever travel, or worse.

Yes, Campy pads can slip out if installed backwards by someone who doesn't know what they are doing. The callipers will also fall off the bike if you forget the fixing nuts. It's just like with those pesky dropout adjuster screws; Campy never really intended for their designs to cater to the lowest common denominator of mechanical skills. However, if that is what appeals to you, Schwinn-approved Winneman center pulls, with the extra alloy plate to retain the shoe rubber, may be to your liking. These are often found alongside the brake safety levers, spoke protectors, and the positive retention device on the hub QR.
