We talk about collapsed hoses all the time but I have NEVER, NEVER, NEVER, EVER seen a hose block fluid flow, ... Until last year when I found two in two weeks! One was on my Grand Voyager that was sitting all winter. The other was on a student's '99 Neon.
The clue is when the brake is locked, it will release when you open the bleeder screw. The problem is rust buildup inside the metal bracket in the middle of the hose. Use a channel lock pliers to peel the crimp open a little.
When the rust pinches the hose, pedal pressure can easily force fluid to the caliper but the caliper can't push the fluid back.
