How does the Electronic Brake System (EBS) with integrated brake blending coordinate service and auxiliary brakes when the driver depresses the brake pedal?

1. It locks the retarder completely out until the brake pedal reaches 100% full travel
2. It prioritizes wear-free retarder torque in the initial pedal travel and seamlessly blends in the pneumatic friction disc brakes as deceleration demand increases
3. It applies friction brakes only on the front axle and retarder braking only on the tag axle
4. It vents air from the air suspension to lower the vehicle center of gravity before braking
