non-recessed brake on fork drilled for recessed brake

If the rear hole on the fork is larger than the front hole, I assume that it's drilled for a recessed brake right?

I picked up an older brake caliper that is non-recessed. And I'm pretty sure my fork is drilled for recessed. Can I just put a washer over the rear hole and put a nut on the thread, or do I HAVE to use a caliper that's designed for a recessed fork?

I've had that issue and solved it by running a die down the brake bolt, hacking it to the right length, and running the die back off. File a little, use a recessed nut. Brake bolts thread and cut easily - I used a cheap die. If you want to keep the bolt from wandering around in that big hole under braking pressure, you'll need a bushing at each end. They may be available, but I had the die in my toolbox, so I didn't look.

what is a "die"? and i assume i can't just take a hacksaw to it because it will damage the threads near the end, right?

Never done it myself, but came across these fittings just the other day:

They may work better for keeping the post centered than a washer alone.

A "die" is a tool that cuts threads. You could take the brake to a bike shop or machine shop and have them extend the threads further down the current center bolt then cut it to the correct length. You can then cut the bolt off with a hack saw but you will have to clean up the cut end with a file to make the nut go on smoothly. Do not cut it before making the threaded section long enough.

For $.25 go with the Rivendell bushings.

The bushings are cheap if you don't have the tap/die set - I already had mine - but I'm always looking for an excuse use to buy another tool.

Well, the OP wasn't even sure what a die is so I think it's safe to assume he doesn't have a proper tap and die set, nevermind metric ones.

Yes, you can use a washer. I did this for the best part of 20 years on one of my bikes. No problems at all. Don't worry about it.
