A COMBINATION of power-assisted ventilated discs (front) and drums (rear) are used on the Premacy. The front discs measure 24mm thickness and 258mm in external diameter, while the rear drums measure 42mm x 228.6mm in internal diameter. Anti-lock brakes (ABS) with electronic brake-force distribution (EBD) is standard. The ABS system uses a wheel-speed sensor at each corner to detect difference in revolution, and three channels to control the front brakes individually and the rear brakes as a pair.
