Have you checked the r/f brake hose?

r/f brake hose looks ok are you thinking it may be collapsing inside

I agree with Mrbizness1. This sounds like a bad brake hose on the front that is not allowing pressure to release back into the system from the caliper. Replace the hose and bleed the system. They do go bad on the inside from time to time.
