I changed the brake hose and nothing changed. Damn it! I used a flare nut wrench and after many tries, I was able to finally loosen the fasteners, the one next to the brake hose was a PIA. Is the banjo bolt the one that connects the brake hose to the caliper? If positive, that one was no sweat with a 14 mm 1/2 in socket and a breaker bar, I loosened it previously when I took the caliper apart.

Could some one please check their 99 Camry CE, no ABS, US model for similarity with the brake line setup in my previous post? Thanks.

I was able to run a wire through the 3 way manifold and through the brake line segment that connects the master cylinder to that 3 way manifold (it connects to the first piston, the one next to the brake booster), so they're off the hook.
The brake line segment between the brake hose and the 3 way manifold is rather long and I couldn't run the wire wire through, but it went in a little bit more than halfway from either end. I'll have to mess more with that one.
I assume that with a faulty master cylinder I'd get pressure in the passenger caliper too, right? I did some reading on how stuff works, and the previously described brake line arrangement is weird, I doesn't have 2 circuits.

Thanks for helping, posting and reading!
