I've been fighting brake problems all summer. We had an issue on our first trip this year back in April so I decided to replace all the original hoses, the master cylinder and the combination valve. Everything seemed to work. Might have had a small leak but we weren't using it much. Then the new master cylinder went out. I replaced that and in the process I pulled off the combination valve so I could get enough leverage to properly seat the pigtail. Turns out no amount of leverage helps. The pigtail just sits on top but it seems to work so I reinstalled the combination valve but I couldn't get one of the 3/8 inch front brake line fittings tight enough to stop leaking. I eventually ended up rounding off the shoulders on the fitting with a pair of vice grips. So, I had a new brake line made up and bought a set of HF flair wrenches. I replaced the line yesterday but I still can't get it tight enough to stop leaking. I used the flair wrench and when it felt like it was going to slip I used a small pair of vice grips that hold the nut tight and that helped but the vice-grips were so small (it's a 3/8 fitting) I couldn't get enough pressure on it to do much good so I used the flair wrench again but with a pair of vice-grips over the end to keep it from spreading and that helped some but it eventually slipped. So, I'm beginning to think that if both the original fitting and the new one both leak when screwed into the same connection in the combination valve maybe the problem is the new (in May) combination valve. Does that make sense or should I just give up and take it to a brake shop?

We were going to leave Tuesday for a 2,500 mile trip but unless I can get this squared away we're not going anywhere for a while.
