Trouble bleeding with motive bleeder

[Vciferni]

Replaced the slave cylinder, hydraulic line and master cylinder in my ranger and got it all together and can’t get it to bleed. I’m using a motive pressure bleeder and pumping it up to 20lbs and bleeding it and it feels great. But when I disconnect the pressure bleeder the pedal looses all pressure and hits the floor. I’m following the directions on the pressure bleeder exactly. Also when I try bleeding it with my brother and pumping it with the pedal, we get no pressure build up.

These systems usually need bench bled before ever installing them. They really should be hung up overnight..
