Because flux capacitors are still too expensive.

Because brake pads, rotors and lines are wear parts.  Auto makers bank on you having to buy parts to repair your car, that way they will get a chunk of cash out of every car they sell for the next 20ish years.  



At any big car dealership, the main money maker is the service department.

Most of us don't want excess friction to break things on our cars.  Especially not the brakes.

The supermagnet's eddy currents act on itself, slowing its decent.

Yeah. Ford wants me to buy brake parts made of super-expensive cast iron, steel and low-grade ceramic, instead of cheap and plentiful copper and neobdymium.

They have a nice hands on demonstration of this at the science museum with a large electric horse shoe magnet and some aluminum plates with handles that you can pass through the magnet.  I could have played with it for hours.

I would assume that a magnet braking system like on a train would cost many times what a lifetime of pad rotor replacement on an average car first off. The simple single piston systems on cars are ridiculously cheap to replace anyways and you should be able to do it yourself after watching a video or checking out a forum specific to your car.

On a model engine forum I go to, a guy had a small air powered hit-n-miss engine. There were two magnets on either side of the brass flywheel to help slow the engine down, so you could see the valve system operate.



First time I had heard of this Lenz effect. Never thought about the dampers on the old lab scales...

Seems like an industry that could benefit from investment and research. maybe not cost effective for cars, but what about large trucks that are brutal on breaks. anything large and heavy.  aircraft, armored trucks, 18 wheelers, etc

Seems like airline companies would be all over frictionless breaks.
