I got it. While taking our 350 in for service, I sat with the service manager who was nice enough to spend time explaining the banjo fitting and how the 2 crush washers situate on the gx470 and he even gave me a way to temporarily plug a brake line while disconnected. So I spent some time cleaning that fitting and after some brushing with pb blaster, the original washer, which was fused, flattened, and scored, came off. I think that was the culprit as I have a clean new one there now with no leaks for the last 45 minutes of test driving. Time for a brake dance. And I learned how to get fused rotors off of a gx470 this week, so I've got that going for me

We have a 2003 GX470 which we love. It's up to aboiut 140,000 miles now. Almost all work has been done at dealership but as of late, I've been making repairs to save money. Replaced the rotors, calipers and pads on the front. Took a few days with all the rust. Everything was fused together. It's all back together and working nicely, then I developed a brake fluid leak on my drivers side rear. Fluid appears to be coming from the lower main bolt that holds the caliper together, but I think it's originating from the fitting where the brake lines fastens to the caliper. After soaking it with PB blaster and coaxing it a bit, I was able to get the old fitting out cleanly. It looks almost like a bleeder screw. My caliper came with 2 brass washers for that fitting. My quesitons: How do the 2 brass washers situate? Is there any kind of rubber or sealing kind of washer I can use there? The very slow leak seems to be coming from that fitting and I'd love to save it if possible. Any ideas on how to get this leak stopped short of just replacing the brake line? Thanks for any help.
