I had a sticky caliper on the passenger side of my wagon. They've got a different caliper than the sedans- so I found a wagon and pulled a caliper. same problem later. Bought a set of and installed the third caliper with new line on that side and the problem seemed to go away- but had brake loss once since then-that was the symptom. Lost power brakes, but had manual if my description is correct. The sticky caliper was heating the rim and fluid to the boiling point and thus I lost fluid pressure and brake power. Problem seems gone after the hose change.
