GENERAL INFORMATION



FEATURES




BRAKING PERFORMANCE



  • 10-inch brake booster is installed.
  • 16-inch disc brake is installed on the front wheels in order to achieve stable braking force and good braking feeling.
  • 11.6-inch leading trailing type drum brake is installed on the rear wheels.

STABILITY



  • 4-wheel anti-skid braking system (4ABS) is adopted to prevent slipping caused by the vehicle wheels locking up, in order to maintain appropriate braking distance, and also to maintain vehicle stability and steering function. <Vehicles with ABS>
  • Electronic brake-force distribution (EBD) is adopted to maintain the maximum amount of rear braking force even when the vehicle’s load is varied. <Vehicles with ABS>
  • According to the fluctuations in the amount of load, load sensing proportioning valve (LSPV) is adopted to control the brake fluid pressure from the master cylinder fairly and prevent the early-lock of rear wheels, improving the stability during braking. <Vehicles without ABS>
  • Front and rear split (fore-and-aft separated type) brake fluid line is adopted. <Vehicles without ABS>
  • Diagonal split (X-type) brake fluid line is adopted. <Vehicles with ABS>
  • Ventilated discs have been adopted to front brakes to improve anti-fading performance.
  • A brake pedal retraction suppression structure that restrains the retraction of the brake pedal and reduces the shock to the feet of the driver in the event of a frontal collision has been adopted.

SERVICEABILITY



  • Diagnosis function is adopted for the ABS system in order to make inspection easier. <Vehicles with ABS>
  • For the front disc brakes, brake disc separated front hub is adapted to make removal and installation easier.
  • ABS-ECU and hydraulic unit have been integrated to make them more compact and lighter. <Vehicles with ABS>
