The front brakes each comprise of a hub mounted, twin piston caliper assembly and a ventilated disc. The inboard

When hydraulic pressure is supplied to the caliper, the pistons extend and force the inner pad against the disc. The
caliper body reacts and slides on the guide pins to bring the outer pad into contact with the disc.
