Your vehicle may have a valve that adjusts for loads and prevents the rear brakes from locking up. There is a bleeder on this valve that needs to be bled before fluid will reach the rear cylinders. This valve is located above the rear axle and has brake lines running to the rear cylinders. The master cylinder may also have a problem. Loosen the lines at the master cylinder to see if any pressure is being generated from the cylinder. The brake proportioning valve may also have a blockage, but this is very uncommon. You will have to work your way back to locate the blockage if the master cylinder is in good condition.
