doing new pads rotors and stainless steel lines today and I encountered a problem. I rounded the nut that goes from the hard line to the new stainless lines trying to get the old line off. Its bad. I tried pb blaster vice grips with no luck. I heard with other cars you could cut above the nut and flare the line with a new nut and problem solved. Does anyone know what size flare to make? Also what size nut is it that goes over the brake line? Please help.

 

For anyone that might come into this situation in the future make sure you get a good set of flare wrenches before trying to tackle the fittings. As far as the rounded one I ended up cutting the line off and attempting to reflare it which did not work so I had to bend a new line. Luckily it was the front driver side so it was a short line.
