The rear T has inverted flare seats, not Euro bubble flare seats.
IMO you are wasting your time with the t- fitting if you still have the stock rubber brake hoses.
It is EXTREEMLY commen, as pointed out earlier, that those hoses deteriate from the inside and block all flow to the Caliper. I didn't believe it could happen, (As the pressure could be as high as 1200psi), until it happen to me.
Change the rear hoses if they are the stock rubber ones and your problem will be fixed!
