Braking System
The Maserati GranCabrio is equipped with a high performance braking system employing
dual-cast technology for the front brakes, a system developed in collaboration with Brembo.
Each disc’s external braking surface is made of cast iron, whilst the hub is aluminium; the
monobloc brake callipers, also in aluminium, are more resistant to deformation than traditional
two-piece callipers. The braking system has two circuits, with four ventilated and perforated
discs. The front brakes comprise monobloc aluminium callipers with six pistons of different
diameters and dual-cast discs measuring 360 x 32 mm, whilst the rear ones feature aluminium
callipers with four pistons of different diameters and 330 x 28 mm discs. EBD is an integral part
of the ABS system, for optimum braking force distribution between the front and rear wheels.
To facilitate uphill starts, the car employs the Hill Holder system, which keeps the brakes on for
a few seconds after the brake pedal is released on uphill slopes, thus enabling the driver’s foot to
shift over to the accelerator pedal without the vehicle moving backwards.
The GranCabrio is equipped with an electronic parking brake, which is engaged by an electric
control on the central tunnel.The car also features HBA (Hydraulic Brake Assist) – a system that
recognises panic braking and then, irrespective of the driver’s foot pressure, applies the brakes
with full force to minimise the stopping distance.
