There are two basic types with individual issues.

1st: The electromagnetic retarder type.

  • This type works by creating a magnetic field and slowing the car using the resistance created.
  • Some of this type are used on cars as "Regenerative braking" on electric and Hybrid cars
  • It can not be used to stop a car as when the car slows down the braking effect gets weaker and finally quits working while the car keeps moving.

2nd Electromagnetic controlled brakes as used on RV sized Trailers.

  • This type uses a magnet to grip a spinning brake and uses the strength of that drag to apply the brakes.
  • It losses effectiveness as the vehicle slows
  • Is not easy to control this system for anti lock braking.
  • Is limited to drum brake technology currently.
