The Autool AST609 is a pulsating brake fluid bleeder for replacing and bleeding brake fluid in passenger cars and light commercial vehicles. The device features a metal housing with carrying handle, an analog pressure gauge on the front panel, and a control button with standard mode and pulse mode. Thanks to the supplied set of seven Adapters, the device can be used on a wide range of European, American, and Asian vehicles, including Mercedes-Benz, BMW, Audi, Volkswagen, Volvo, Porsche, Ford, Toyota, Honda, Hyundai, Nissan, Dodge, Chrysler, and Jeep.
The AST609 is placed on the brake fluid reservoir via the matching brass Adapter and powered with 12 V via the supplied battery clamps or power Adapter. In standard mode, the device provides continuous pressure to move fresh brake fluid through the system, while the pulse mode generates alternating pressure pulses that release air bubbles in brake lines, ABS blocks, and clutch circuits. The pressure is read on the pressure gauge, and the device status is visible via the POWER and WORKING indicators with separate START and STOP buttons.
ADVANTAGES
IMPORTANT NOTES
Applications and functionalities
The AST609 supports the following workshop operations on the brake system:
- Brake fluid replacement: Supplies fresh brake fluid under pressure via the reservoir, allowing old fluid to be drained at each bleed nipple.
- Brake system bleeding: Removes air from brake lines after replacing brake calipers, master cylinders, or brake hoses.
- Pulse bleeding: Generates pressure pulses that loosen air bubbles in hard-to-reach places such as ABS modulators.
- Clutch system bleeding: Usable on hydraulic clutch circuits with a compatible Adapter on the clutch fluid reservoir.
- Pressure monitoring: The built-in pressure gauge shows the current working pressure during bleeding to monitor the brake system.
Special features and capabilities
The AST609 stands out with the following features:
- Dual operating mode: Switchable between standard mode for regular fluid replacement and pulse mode for loosening trapped air in the hydraulic circuit.
- Dual power option: Can be powered from the vehicle battery via clamps or from mains power via the power Adapter, without module change.
- Status indication: Separate POWER and WORKING LEDs immediately show whether the device is powered and if fluid is actively being moved.
