What are the sizes of all the brake fittings?

[rwc265]

And what style of flares? My 01 vic I believe used bubble flares and that's what I have a tool for but I can't find any definite answers on if my 09 is double or bubble, or if the fittings are metric or standard. I also need to know what size the ABS module fittings are since I want to replace the lines front to back, also gonna do new flex hoses. As to why I need this info...



As far as I can tell, the lines themselves aren't rusted but the unions are. I wanna get it taken care of but believe it or not my vic's unions were worse for a long time and never popped, so I probably have time.

So as far as I can tell the connections at the flex hoses seems to be 3/8"-24 or M10x1.0 depending on which brand you buy based on what I see on Rockauto. IDK if it's mislistings or if the sizes really are different. I'd like to be sure before I buy any parts. I also still haven't found any solid answers on what size the threads are for the ABS module, and what flare type the truck has.
