Negative. The only thing that was really a problem was removing the pads from the holder. They were stuck in there and wouldn't slide free. I had to work it with a screwdriver and kind of tore the sides off. That's what took a long time.

The rest of it was slow, because I'm generally mechanically clumsy and take a while to get things centered, but I didn't get hung up on any of it.

Anyway, now there's something wrong with the cabling, apparently (which I recently replaced). Front brakes are sticky. The problems never end.
