Ok, I'm needing to put a front brake on my 1970 Centurion which I'm using 700c wheels on. I bought an R556 front brake with recessed nut so the plan is to drill into the fork, not a big deal. My question is what order do I use the knurled washers that came with the brake? I'm thinking it should be like this: brake-knurled washer-fork-knurled washer-recessed nut.

Sorry if this may be a stupid question, but I'm not wanting to put this on incorrectly and have everyone be like "Oh wow this guy is ********."

I tried searching for a close-up picture of a front brake but didn't have any luck.

Thanks in advance for the help,
David

This is not a stupid question. The washers go in the front of the fork between the brake and the fork.

You will most probably need a 5/16 drill bit for this.

Another option would be a clamp-on [keirin] front brake kits...

Thanks, I have already drilled the fork I was just wondering how to arrange the knurl washers.

The star washer goes between the brake and the crown:

Also, the pupose of the knurled washer is to allow the brake to be centered with a cone wrench on the flats without having to loosen the mounting bolt.

how well do those things actually stop, anyway?

from what I read some time ago in the "clamp-on brakes" thread (too lazy to search for it now) it stops as well as any other front brakes.
NOTE: i do not have personal experiences with clamp on brakes.

I'd say that drilling out your fork in order to update the brake on your fixie is neither stupid nor noob. I'd been working on bikes for years before drilling out my Trek and was sweating bullets.
