Dual Piston caliper and rear disks cant stop

[Cordless]

I swapped my front end for a dana 30 and a ZJ outer knuckle swap witht he dual piston calipers. then i swapped my reqr end with a 31 spline 8.8 with disk brakes. I cant seem to get any braking outta any of it tho. I used the stock ranger master at first then I swapped out a 4 wheel disk brake explorer master and i still cant get it to properly stop me. when the vehicle is one the pedal is kinda dead. if i hit the pedal really hard i get a little out of it but not much... nothing i can actually drive with... any ideas?

check to make sure that the calipers have the bleeder screws ABOVE the incoming brake lines. i have the same SAS and brake swap on my ranger and it stops on a dime with the stock master cylinder. haha we live in the same damn city man. message me if you need any help with your truck

Did you bench bleed the master cylinder?

Yessir I did bench bleed the the master I am gonna pull it off and do it all again and then use a vacuum bleeder on my brakes to ensure all air is out and see how it turns out
