There must be air in the system some where. i am not sure of the year ,make and model of this van and also not sure of the brake system, for example if you have drum brakes in the rear then first adjust them.
The next step is to fill the master cylinder, make sure there are no leak anywhere.Next step start at the master cylinder, at the line to master do not worry about abs system. have someone inside ready to pump brake pedal and hold.Have them pump pedal three times and hold pedal with a little pressure.make sure as you open the bleeder they push on pedal and keep foot on brake until you tell them to pump again. the pedal is to be pumped three times every times.
With pedal pumped start at master lines, open one allow to bleed a little then close and move to next and allow to bleed. if master has more than two lines then pump again and do two, open one and close then open two and close then pump again. After master is bleed a few times and no air comes out then move to right rear wheel, pump three times and hold while you open bleeder, this is to be done about four times to make sure you get a good flow of fluid with no air .
NOTE: always keep master cylinder full, check after each wheel. make sure the person pumping the brakes does not lift until you say and the bleeder is closed. After the right rear wheel you will move to left rear and then right front wheel and last is the left front wheel.
Make sure there are no bad wheel bearings, lift wheel of the ground and grab and check for movement by pulling wheel out and in from top to bottom, the last thing is make sure the caliper slides are free moving.
If the caliper does not slide on the bracket freely then the piston will not stay on pad and pedal will need to be pumped to get a pedal. good day.

Some vehicles have a splitter that will shut off fluid to one wheel in case you blow a brake line. It has to be recentered to get fluid to both sides. Boy that brings back memories of my old Triumph TR4!
