Guys - getting ready to tackle my brakes and always looking to get the proper tools, I just don't like to buy more than I need - I do not own any flare wrenches but need to pick up a set for sure - for doing the brake hoses what sizes do I need? Especially for the nut on the hard line on the chassis as that is the one that is most needing a flare to avoid rounding it -

I can get individual wrenches off Ebay and wondering if I can get the job done with just 2 wrenches (say a 9/11mm and 12/14mm combo), otherwise I'll get the 6 piece SAE/Metric combo from Home Depot which has a 9 x 11mm, 10 x 12mm, 13 x 14mm, just confirming I can get the job done with those -
