Ford V8 cars of the late 30s before finally joining the rest of the manufacturers with hydraulic brakes in 1939, used a steel cable in a sheath for their brakes and called them steeldraulics, fine if the car was driven often, but if they sat a bit, or got ice down the cable you had free free-wheeling! So they had a special pliers for these? I suppose right up there with the rarity of the rocky mountain oyster shucker?
