First, why would you need to open brake lines to do the brake job? Second, you stated that you pumped all the fluid out, and THEN filled the reservoir? If that's the case, the entire system is full of air. If the vehicle is equipped with ABS, you better take it to a shop because improper bleeding procedure may damage the hydraulic unit, and you will end up with over $1,000 worth of repairs.
If you do the bleeding yourself, start with the furthest from the master cylinder wheel. Again, it's too long to describe the entire procedure in detail, so you still are better off taking the vehicle to a shop.

If you do not know how to properly bleed brakes, I recommend towing the vehicle to a reputable repair shop. If you still insist on doing it yourself, you could open all four bleeder screws on the front and rear brake calipers(rear wheel cylinders) and allow the brake fluid to drip out of the bleeders while adding brake fluid to the master cylinder. Be careful not to run the Master Cylinder less than half full or you will have to redo everything a second time. If you want to bleed them more efficiently, have someone sit in the car and you start the bleeding procedure at the right rear wheel. (Passenger rear) Have somone push the brake pedal down and hold it, crack the bleeder open and count to two, shut the bleeder and have the other person let off the brake pedal. (Close bleeder before they let off brake pedal) do this two or three times and then move to the driver rear wheel and repeat the procedure. Then go to passenger front wheel and do again. Finally bleed the driver front wheel in the same manner.
When done, start vehicle and check pedal firmness, hold pedal and see if it holds firmly or tends to sink to the floor, also look for brake warning indicator lights on dash. If no lights are on and the pedal feels firm, take vehicle for a slow, safe test drive in a non crowded area. If pedal is still sinking after you bleed brakes in this manner, I suspect you have a bad master cylinder or you need to try bleeding brakes one more time, exactly as I outlined here. Good Luck.

Wow!!! First of all don't ever, EVER, EVER!!!! work on brakes again! Not until you read a repair manual on brake systems and how to diagnose problems and make repairs. You are going to get your wife and family KILLED!!!
When your brake pedal goes all the way to the floor, it does not indicate bad brake pads, it indicates a failed master cylinder that needs to be replaced.
You don't just pump all the fluid out and add more without doing it slowly and properly bleeding the air out of the brake lines at all 4 wheels.
Don't do anything else to your van. Have it towed to the nearest brake shop and let a professional do the job properly.
I don't mean to be harsh here, but if you can't stop, somebody will die. Brakes are not a do-it-yourself job unless you are absolutely sure of what you are doing and why.

Your not suppose to pump all the fluid out, your suppose to bleed the brakes. Have someone get under the car and you inside the car. Hold the pedal down and have them open the bleeder valve until your foot goes all the way to the floor, hold the pedal, while they retighten the valve, and re pump up the brakes. Keep doing those steps until you get a full pedal, and make sure your fluid stays full while bleeding. Your pourpose is to drain all air out of your brake lines, so keep bleeding until you can open the valve with just fluid and no air comes out.

i own a repair shop,and you have anti lock brakes on this vehicle,and you cant exactly just start pumping them out ,like you could the older cars ,now there's about a 8 step process you have to go through to get them working right again,you,ll probably wind up having to have a repair shop do this,,anytime you do anti locks brakes don't try to pressure bleed them,you have to gravity bleed them,you might can purchase a good repair manual ,and get them to work right again,good luck,i hope this help,s.
