Had this van in the shop for three weeks now and I have never had such a problem. Replaced master cylinder along with all new hoses and bled countless times and still no brakes. I can pump the brake six or seven times and get pressure, but it slowly fades out. Someone please explain to me what i am doing wrong or what is happening? Thanks.

if the vehicle has an ABS system you have air in the ABS part and will need a scanner to open the ABS valves and bleed the system that way. it takes a specialized scanner that most pros have.

HMAC 300 might have the right answer.

I'm just giving you another possibility.

Could be your bleeding technique?

Before you spend $$$ look over the way I bleed the master cylinder and the brakes.
