Parking brake weak on Caravan 2000

The parking brake foot pedal hits the floor and the brake does not hold well. I found there is no brake cable adjustment as in many of my previous cars. The footbrake pedal assembly is suppose to automatically take up cable slack and also take up any brake pad wear. I pulled the rear wheel hubs and found a reasonable amount of brake pad like a little over 0.100 inch over the rivets of the pads. But it did not look like the pad automatic slack adjuster was not working. After blowing the dust off and removing the brake assembly parts I found all seemed to be in great shape. Even the adjustment screw turned very easily. Not sure why it is not working. Even with the hub off the adjusters did not take up slack with the brake pedal depressed. So I installed new wheel cylinders, (brake cylinders), $10.50 each. The originals would have been easy to rebuild as there was no pitting. It looked like the pistons were gummed up a little. Linda helped with bleeding the brakes. She is an expert at this and it works out easily as we can work together well. Now let time pass a little and see if the adjusters will now take up the slack. The brakes are working great except for the parking brake is still too slack.
