Usually they are an 8-10mm (Japanese cars use metric everything). Grab a set of flare nut wrenches if you can as they are much safer to use when bleeding brakes since the metal used in the bleed screws is fairly soft. My set from AutoZone was about $17 and has 6 sizes.
The bleed screws were 10mm on my 2014, but I cannot say for sure what the First Gen uses. Check for brake install DIY's for the 1G and see if they cover the tools needed - the smallest size wrench they list will generally be for the bleed screws.
@drizzoh Hi, My car mechanic told me his old mistakes. So to successfully get the work done correctly from the first time:
1. Clean the area/vicinity of that end.
1a. Be sure that you have light and can see what you doing.
2. Spray a lubricant/penetrant oil, on that end.
3. Use a tool that will fit that size (something adjustable).
4. Start turning slowly. Something always will be in your way.
5. Check the little pipe lines for damages (mechanical/corrosive).
6. Remove the end.
That end is usually made from aluminum. Be careful this is easy to damage.
Here is the tool that works on my Scion xB 2004.
This will work on any car, because is adjustable.
You do NOT ever want to use an adjustable/crescent wrench on bleeder screws...use the right sized tool for the screw and, as mentioned previously, flare nut wrenches would be the best route to go as they 'grip' more of the screw leaving far less chance of slipping/stripping the head.

Cheap tools that done the work right.
I distinctly remember a crusty old Master Mechanic testing my knowledge of vehicles, tools and how to use them one day many years ago. He held up an adjustable wrench pretty much like you recommend using and asked me, "What's this?" I thought about it for a second because I knew he was testing me, then replied, "It's an adjustable wrench, sometimes called a Crescent wrench." He glared at me and said, "Wrong! It's an adjustable rounder and all it's good for is rounding off perfectly good fasteners. Don't ever let me catch you using one in my shop!" You might want to remember his words.
Looks like my car mechanic some time needs more tools!!!
Or, as mentioned any number of times before, maybe you just need to find a new mechanic. I can think of one instance where I saw a professional mechanic use an adjustable wrench and that was in getting a clutch fan off a Ford Lightning...nut size on that fan is like 1 5/8" and he said he couldn't justify spending the amount that wrench would cost for the few times he would use it. That and the fact that the stock clutch fan was usually coming off to be replaced with an e-fan anyway so it was a 'throwaway'.
Need help..Brake Bleeder size?
