DISC brakes are provided at each corner of the Impreza. At the front, low-friction high-strength 273mm diameter ventilated discs are used, with heavy duty twin-piston floating callipers. Rear brakes have 262mm diameter solid discs with single piston floating callipers. All Impreza models have tandem brake boosters and the brake pedal leverage is now lower to decrease pedal travel and provide a firm brake pedal feel. Four-channel, four-sensor Bosch 5.3i anti-lock brakes are fitted standard on Impreza RV.
