Anti-Lock Brakes Bleed

BRAKE SYSTEM BLEEDING - HYDRAULIC SYSTEM
Anti-Lock Brakes Bleed

Note: Carrying out the System Bleed function drives trapped air from the hydraulic control unit (HCU). Subsequent bleeding removes the air from the brake hydraulic system to the bleeder screws.

Note: The engine must be running to provide adequate voltage to the HCU module during the anti-lock control portion of the system bleed.

1. Connect the NGS Tester.
2. Start the engine and depress the brake pedal to half of the full travel position.
3. Access FUNCTION TEST mode and press the trigger to run the SYSTEM BLEED FUNCTION.
4. Manually bleed the brake hydraulic system.
5. Repeat the procedure carrying out a total of two NGS Tester cycles and two manual bleed cycles.
