What is the size of the bleeder screws on the Tacoma?

I tried to search, but didn't really find anything. I've Googled a bit, and think it's 10MM. However, eyeballing them they almost looked like 8MM. I didn't try a wrench on them, and I was in a hurry when I was doing a tire rotation.

By this I mean, what size wrench, not what size screw to replace it with. However, if anyone knows the specs of the brake bleeder screws themselves, it might be handy to have those as well in case someone breaks one or something.

 

Yes 10mm - use a flare wrench if you have one

 

OK, thanks. For some reason they *looked* smaller, but like I said I was in a hurry.

 

This is an ancient thread, but some extra tips…

If your bleeders are OEM they are 8mm, however they commonly seize up and can break off if not careful, so there is a good chance someone before you broke one off and replaced with non-OEM which may actually have a 10mm head. I like to break loose slightly first with 6pt socket & ratchet, then use the closed end of wrench to open/close with bleed hose attached.

Regarding brake hard lines, you would use a 10mm “line wrench” also called “flare wrench” to loosen/tighten the brake line fittings on the master cylinder, front calipers & rear drums. Don’t use an open end wrench, you will round the corners off for sure.
