Optimal Performance
- Top travel speed and gradeability
- Smooth initial acceleration
- HydroMaster brakes for reliable braking power
The braking system uses a vacuum-based HydroMaster system as a brake assist unit. Vacuum pressure assists power cylinder operation, and the wheel cylinders operate due to power cylinder pressure, resulting in excellent braking performance. Even if the engine stalls, fluid flows from the vacuum tank to the assist mechanism to guarantee reliable braking power. The eight-ton type employs a full hydraulic power brake.
