Complt Brak syst rebuild ACHIEVED

Recently I had begun replacing the brake lines, buying new ones that were pre made but also using a flaring tool when I needed to shorten a length or when I bot a 25 ft roll of brake line. I never used a flare tool before, but I thought I had done a good job at teaching myself how to use it, comparing the flares on the ends of the premade pipe to what I had formed with the tool.

I replaced all the lines hard and soft, bot two new old stock front wheel cyls and restored the other two at the back of the rambler, and also put on a new master cyl from rock auto, which was identical. 

I reused the old four port junction block that sits on the firewall, but bot a new three port junction block at the back axle and bot a new two port union after the four port junction. 

Yesterday me and my neighbor frank who used to sell ramblers in the sixties tested out the brake syst I built. There was a few leaks that I apparently fixed by tightening the nuts at the compression fitting locations and upon further brake pedal pressing and inspection with the flashlight, and wiping with a cloth to see if there was new fluid coming out, I thought I had most of them fixed, other then the concerning super tiny amount of fluid wetting the area near the very thin copper washers on either side of the hollow bolt that screws into the end of the mc. Those copper washers have circular patterns stamped into them that fit into corresponding impressions on the old hollow bolt, this is obvious to me as a possible leak as the copper washers are old and have already been compressed. (might have to do a fact check on that) But after work today I went to check and see if the leaks increased or if new ones presented them selves and the answer was yes, I emptied the fluid from the lines by bleeding the brakes at both rear wheels.

Now I think what I have to do is do all of the work all over again, this time with a different flare tool, I want to try a different brand, and I wrecked the one I used for the whole job, the larger size brake line 5/16 was too much stress for it, right at the end of the job of using it to flare all of those lines the tool broke, and I had to use the small vice I have to compress on end and a C clamp to compress the other end of the flare tool, it was kinda nuts. 

I also want to read some things online about the technique of flaring, which I didn't do the first time. 

Anybody got any advice as to how to not waste all that time all over again? That advice would be appreciated!

Completely agree with BB69.  Cheap flaring tools are nearly worthless unless you get lucky making a double flare w/o leaks.  The "good" flaring kits are quite expensive.  Might be worth it to bring it to a mechanic who already has the kit, esp. if this is a one-off experience.

I saw there was concerning rings cut into the seats of the  seating areas on the four port junction block... this also might be why it leaked at that spot.

Apparently your not supposed to tighten the crap out of them, but when it startd leaking I thought I should and did, hope I didn't ruin those seats. The one new wheel cyl leaked really bad, maybe it's the new soft lines? I looked at the new ones and old ones and saw they were identical.. Don't know why it would leak like that.. I checked to see if a machine shop could resurface the seats of the junction block and explained thoroughly and also sent a real good picture, and they sadly said they didn't have the set up to do that work.

What would be the bets way to get those seats resurfaced? I dont think the wheel cylinders will be wrecked, since the seat, at least for the front wheel cylinder is what I would call a depression seat... It is a cone shaped seat machined downwards... But if I can't find a new four port junction block, I've looked but haven't found one yet, maybe I'll have to get the seats resurfaced at a high cost, or maybe try and find some new junctions or some adapters? the line leading away from the mc is a bigger size, going into the larger port of the four port junction block, then the three other ports are the normal size brake lines leading away to the other brake lines and junction blocks.
