BRAKES
Features
-
A DSC HU/CM has been adopted in which the hydraulic unit (HU) and control module (CM) are integrated with a built-in brake fluid pressure sensor.
-
Magnetic encoder type ABS sensor rotors have been adopted.
-
Semiconductor element type ABS wheel-speed sensors have been adopted.
-
The following systems, mechanisms, and functions have been adopted to enhance safety.
-
Intrusion-minimizing brake pedal
-
Antilock brake system (ABS)
-
Electronic brakeforce distribution (EBD) control
-
Traction control system (TCS)
-
Dynamic stability control (DSC)
-
Electronic control brake assist
-
Vehicle roll prevention function
-
Hill launch assist (HLA)
-
A electric vacuum pump has been adopted to compensate for the decrease in intake manifold vacuum applied to the power brake unit caused by the retard intake valve closing.
-
Center lever type parking brake, adjustable from vehicle interior, has been adopted.
