Introduction - BRAKING SYSTEM

This braking system consists of two independent cross-over hydraulic circuits (that affect one front wheel and the opposite rear wheel, e.g. right front with left rear and viceversa). This allows braking on both sides of the car if the circuit is faulty so that stability can be maintained.

The versions are fitted with front disc brakes and rear drum brakes. Some versions have self-ventilated discs on the front wheels.

All versions are equipped with TRW430 A.B.S. anti-lock brakes with four active sensors and four separate channels, plus EBD function (electronic brakeforce distribution between front and rear wheels) Characteristic of working principle 3340 A(B.S. ANTI-LOCK BRAKING SYSTEM .).

The main feature of the active sensor is the fact that the signal is processed directly by the sensor instead of being sent to the ABS control unit so that the system can cut in immediately.

Further electronic systems are added on different versions. These include:

  • ASR, active slip regulation during acceleration
  • ESP: vehicle dynamic stability control,
  • HBA, increase in braking pressure during emergency braking.
  • HH, hill start braking

To ensure a prompt response to brake pedal action, all versions are fitted with a power unit including a 9' brake servo.

The pedal unit consists of a mount with clutch pedal (not required on versions with Selespeed) and accelerator pedal in plastic and the brake pedal in steel as usual.

Handbrake configuration is conventional and features steel lever and links acting on the rear brake caliper mechanism.
