After letting my car sit over the winter, I noticed the brake pedal seemed soft. So I changed out the brake fluid and vacuum bled all the calipers. Only the right rear caliper would not vacuum bleed. When I bled it using the pedal, air continued to come out. There are no signs of fluid leakage. Can a seal in the caliper go bad allowing air in, but not showing any fluid loss?
Or is there another possible problem?

I thought I might have a runout problem, but that tested out OK.
After pumping the brakes I took another shot at bleeding that caliper last night. No problems! The rubber seals may have just been a little seated after sitting all winter.

The flex lines (trailing arm to frame) often go bad. The inner layer breaks away and causes a blockage. They will look fine on the outside.
They may be restricting the flow of fluid resulting in an incomplete bleed.
