If you don't mind me jumping in. On old VW's with old brake hoses, it's not unusual for the brake hose to deteriorate internally and become partially, or completely, plugged up. The brake pedal will initially feel somewhat hard, then go soft as the fluid slowly gets by the blockage.
If you don't get much fluid or pressure coming out of a bleeder you need to disconnect(unscrew) the hose from the wheel cylinder and see if pumping the brake pedal will push fluid out the end of the disconnected hose. If nothing, or very little, then remove the brake hose and try to blow through it with compressed air, or try to pour fluid in one end and see how much comes out the other end. This will give you an idea of the amount of blockage.
Although you can sometimes run a wire through the hose and clean out the blockage, this is purely a desperation measure. Old hoses, especially cracked ones, or ones with soft or thin spots, should be replaced for safety's sake.
