I had this on my Subaru. After a long highway run it would make the car almost
undriveable, the shaking was so violent. It was a warped rotor compounded by a
sticky caliper. The caliper wouldn't retract when the warp came around, so
things just got hotter and more warped, and more grabby. If those calipers
are original, might want to go ahead and rebuild/replace them with the
rotors.
