78 FJ40 with dual reservoir master cylinder. I replaced the master cylinder with a new Aisin along with all new brake lines in the front. I couldn’t get any brake fluid out of the rear wheels, so I’m about to start taking every brake line connection loose to diagnose the problem. I started at the new master cylinder. I pulled the brake line for the rear brakes off (between the 2 reservoirs), pumped the brakes, and no fluid comes out of the reservoir. Am I missing something or is my new Aisin MC a dude?
I was able to bleed the front brakes and if I loosen the brake line at the MC for the front brakes I do get fluid coming out.
