 From March 1976, late in the HJ series, an electromechanical rear drum anti-lock braking system (ABS) was made available on the Caprice.This system, a Delco-Moraine unit, carried over to the subsequent Statesman HX models, but after the introduction of rear disc brakes on the Statesman HZ series, ABS was not seen on another Statesman or Holden model until the Holden Calibra coupe and Holden VQ Caprice in 1991.This new ABS system was the electronic Bosch patent system operating on all four-wheel discs.
