Maserati GranCabrio

4. Braking System

Braking System

In analogy with the other Maserati vehicles with the 4 7L engine, The GranCabrio is equipped with a high performance braking system employing dual-cast technology for the front brakes, a system developed in collaboration with Brembo It has the following characteristics:

• Tandem master brake cylinder 25,4/27 mm, vacuum operated brake booster, separated hydraulic brake circuit using an X-pattern

• Front axle: monobloc aluminium 6-piston brake calipers with differential diameter (30/34/38 mm). Dual-cast brake disks, ventilated and perforated, diameter x thickness 360 x 32 mm. Brake pads Jurid 673 GG. Monobloc callipers are more resistant to distortion than 2-piece callipers; this means lighter materials can be used, in this case aluminium, reducing the weight of the component. Furthermore, the calliper is more efficient at all working pressures: this means a shorter brake pedal stroke

• Rear axle: monobloc aluminium 4-piston brake calipers with differential diameter (32/36 mm) Ventilated and perforated discs, diameter x thickness 330 x 28 mm Brake pads Ferodo HP1000.

• 6 available colours for the brake calipers: black (standard), red, titanium grey, yellow, silver and blue.

• Drum in Hat parking brake, electronically operated (EPB) with “auto-apply”, “drive away” and “pre-release” functions

Braking System

MSP system

Like other Maserati models, the GranCabrio is fitted with the MSP system (Maserati Stability Program) This system controls all the vehicle dynamic functions related to braking, cornering stability and traction control. The different dynamics are controlled by a number of specific functions, all integrated in the NFR (Bosch ESP 8.0):

• ABS (Anti-lock Braking System): prevents the wheels from locking during braking

• ASR (Anti-Slip Regulation): prevents the wheels from slipping during acceleration

• EBD (Electronic brake force distribution): assures the ideal distribution of the brake force between the front and the rear axle based on vehicle load and dynamic conditions.

• MSR (Motor Schleppmoment Regelung): electronically controls the engine braking torque during downshifting to ensure the stability of the car

• MSP (ESP), (Maserati Stability Program): controls the brake of each wheel individually to ensure the vehicle’s stability during cornering

• HHC (Hill Holder Control): assists the driver during uphill driving away by preventing the vehicle from rolling backwards in the time between the lifting of the brake pedal and the depressing of the accelerator pedal.

• HBA (Hydraulic Brake Assist): assistance during emergency braking (NEW!)

Hydraulic Brake Assist (HBA)

• Offers assistance to the driver in the event of an emergency braking

• Integrated function in the Bosch ESP 8.0 unit (NFR)

• Applied for the first time on the GranCabrio model. Other Maserati models will follow.

• It uses the information from the internal hydraulic pressure sensor to detect the speed with which the driver depresses the brake pedal During an emergency braking, people often depress the brake pedal quickly but with insufficient force

• It increases the brake pressure by means of the hydraulic pump if an emergency braking situation is detected.

• This function reduces the stopping distance in emergency braking situations and therefore improves safety
