Dura Ace BR-7400 and BR-7403 brake pads not replaceable?

I was just told that the brake pads in Dura Ace BR-7400 and BR-7403 are not replaceable. That is, the rubber pad and holder is a single unit. Is that correct?

I snagged a set of 7403 brakes a good while ago, here's the pads/holders:



I wanted to replace the dried out pads, and from memory it was easier to source a set of newer pads and holders (with replacements available) versus replacing the pads in the originals. Kool Stop Dura 2 pads will slide into the original holders, but they're a bit longer than than ideal.



I wound up just using a set of currently available BR-6800 pads and holders. Kool Stop pads fit these holders and are installed in the below pic, though not visible.



BR-6700 looks an even better aesthetic match.

Slice the pads off, works fine.

BR-6403 is about the same thing.

I don't know about the 7400 holders but my 7403s look like the ones above and the pads do slide out through the open end. I recently replaced my pads with Koolstops meant to fit newer shimano brakes but I don't remember what model # pads. Mine seemed to fit better than the ones shown above but still stuck out maybe 1/8" inch. I just trimmed the ends with a utility knife. You should be able to get new pads to work with a little trimming and sanding.
