Improved safety

• Intrusion minimizing brake pedal adopted

• ABS adopted

• Electronic brakeforce distribution (EBD) control adopted

• Dynamic stability control (DSC) adopted

• Roll over mitigation (ROM) adopted

• Electrical brake assist control adopted

• Hill launch assist (HLA) adopted

• Tire pressure monitoring system (TPMS) adopted

Improved braking force

• Large diameter front disc brakes adopted

• Large diameter rear disc brakes adopted

• A vacuum pump adopted

Improved serviceability

• Enhanced malfunction diagnosis system for use with Mazda Modular Diagnostic System (M-MDS)

• Center lever type parking brake, adjustable from vehicle interior, adopted

Size and weight reduction

• Integrated construction of the hydraulic unit (HU) and control module (CM) adopted for the DSC HU/CM

Improved brake pedal operability

• A master cylinder with smaller diameter long-stroke type has been adopted

Improved reliability

• Semi-conductor element type ABS wheel-speed sensor adopted

• Magnetic encoder type ABS sensor rotor adopted

• DSC HU/CM with built-in brake fluid pressure sensor

• Receives the DSC control signal from the sophisticated air bag sensor (SAS) control module instead of the conventional combined sensor
