Aside from the fact that it's a cheap technique (one relay replaces
a whole slew of servos, hydrailics, brake pads and disks) - it also
doesn't wear out like friction-based brakes do. For Mars rovers, the
power recovery must be worth having - but also, friction-based brakes
convert the kinetic energy of the vehicle into heat - and in places with
very low atmospheric pressures, it's no so easy to cool brakes as it is
here on Earth.
