Brakes in Murrayfab Engineering trailers are built to Australian Standards. In all of our trailers over 750 Kg GVM (Gross Vehicle Mass) we install Braking systems. Trailers with a GVM from 750 Kg to 1990 Kg require a single hydraulic or electric brake. From 1990 Kg to 4500 Kg GVM, a 4-wheel electric braking system is required including a Brake-Away safe unit.
