What flare wrenches for the MC and prop valve?

Guys, what size flare wrenches do i need for a STOCK 87-93 Master Cylinder and prop valve?

I need to disasseble one for the lines and want to have the correct wrenches before I go.

I just got my hands dirty for you! On my car, both of the PV fittings fit a 11mm or a 7/16" flare wrench. For the rear MC it took a 12mm, while the front it took a 14mm. I didn't have any other SAE flare wrenches in my tool box to try. They were all a bit loose fitting, with the 11mm fitting the best.

Hope this helps!

Yes it does. I don't have any metric flares so i would have shown up with SAE only.

Time to go get some metric wrenches now
