Need flare nut size

[warlord]

I been doing searches and could not find anything to tell me what sizes are the two flare nuts coming out of the power master cylinder, looks like there are two diffrent sizes the one towards front of car is bigger than the one towards the rear,

Can anyone please tell me what size are they. I need to do a bench bleed and the master cylinder is still on the car

Give me a minute, I'll go check.

I think they're both the same size, but..... a 14mm fits the rear one quite tight, but my front has some burrs and wont allow the 14, however, a 9/16" works just fine, get those two and you should be good to go depending on the condition or your fittings.

when i don't know what size a fastener or fitting is, i just keep putting wrenches on until i find the one that fits..
seems to be faster than waiting for responses online..

Bleed it on the car. That's what we did.
Might want to invest in some line wrenches. Just one goofed up fitting makes them worth it.
