No rear brakes after 4 wheel disc swap?

E-brake cable attatched to caliper,then e-brake needs to be cycled to pring piston to rotors. Thats the adjuster.
E-brake with seperate shoes inside rotor hat then thats a different setup.
When bleeding,whoever is on the bleeder screw needs to open it more than just cracking it,like 1/2 turn. Slow movement of fluid will retain air in the line.
Residual valve for drums is 10 psi, disc is 3psi.
Check prop valve, it could be shuttled over. I check with key on, and if brake warning lamp is on,then it needs recentering.

Ok how do you tell if its shuttled over? And I'm assuming the prop valve is whats down low below the master cylinder? Thought that was just a distribution block and I didn't have a prop valve. But ill check it out tomorrow. Thanks
