what size brake bleeder values for 91 Accord?

I'm thinking about installing one-way brake bleeders to so that I can bleed the brake lines as a one-person project. I went to the local auto parts store and found three sizes: 1/4 inch, 7mm, and 10mm. Anyone know which size I need for my 91 Accord LX?

I don't know, but you know they aren't standard sized, so you can throw the 1/4 out.

IIRC they are kinda small, I'd bet on 7mm.

But that's just a guess.

I always just pulled the bleeder screws out and kept feeding the master cylinder fluid, let it gravity bleed. Worked well enough.
