Key Features
Standard and Fast Pulsating Pressure Modes
Two-Wheel One-Person Service
With the correct setup, the pulsating electric brake-oil exchanger supports simultaneous brake-fluid exchange at two wheels and can be operated by one person, reducing repeated manual bleeding work.
1.5–2.5 bar Service Modes
Select Standard Mode at about 1.5-2.0 bar or Fast Mode at about 2.0-2.5 bar. Use the front pressure gauge and adjustment knob to monitor and control working pressure throughout the service.
Used Fluid Recovery
Recover used brake fluid during service to keep the work area cleaner and make replacement easier to manage.
Water Separation Filter
The air-inlet water-separation filter helps remove moisture before air mixes with the oil path, supporting cleaner service quality.
Low Oil Protection
Low-oil protection helps reduce the risk of operating the equipment without enough brake fluid in the supply bottle.
Portable Bottle + Hose Storage
The compact body includes a carry handle, filling-hose hook, pressure gauge, indicators, fuse, power interface, and a dedicated bracket for the 1L corrosion-resistant filling bottle. Visible bottle graduations and the hook keep the service setup organized.
Two Power Connection Options
Use the battery-clip power connection or a compatible mains adapter, matching the setup to the unit requirements before operation.
Seven Reservoir Adapters
Match one of seven reservoir adapters to the vehicle opening and confirm that it fits and seals correctly before service.
3 Years Warranty Support
Main unit: 3-year warranty. Standard accessories: 1-year warranty. Warranty Policy.
Safe Use
Match Power Version, Pressure and Adapter Fit
Brake Fluid Standards
Applicable to DOT3, DOT4, and DOT5.1 brake fluid standards. Do not use other liquids in the machine.
Seven Adapter Types
AST609 includes B01, B02, B03, B04, B05, B06, and B07 adapter types for broader reservoir compatibility.
Confirm Adapter Fit
Use the adapter image and listed brand or series labels as an initial selection guide, then confirm exact vehicle fit before ordering.
First-Use Air Emptying Required
Air-emptying must be performed before first use. Fill the equipment line with brake fluid and remove air before connecting the device for normal vehicle service.
Use Correct Working Pressure
The pressure regulator is typically set around 1-1.5 bar before leaving the factory to help protect the fluid reservoir chamber and secondary sealing ring.
Avoid Excessive Pressure
Lower pressure may be used for exhaust or fluid replacement when suitable. Excessive pressure may damage the brake master cylinder or sealing components.
Check Connections Before Use
Before changing brake fluid, check every connection for leaks and inspect the connection hoses for damage.
Use Brake Fluid Only
Use the AST609 only for brake and clutch brake-fluid service. Other liquids may damage the brake maintenance device.
Prime the Fluid Line
Fill the delivery line with the specified brake fluid and remove air before connecting it to the vehicle.
Handle Brake Fluid and Power Safely
Brake fluid is toxic. Avoid skin and eye contact, and wear safety goggles and protective gloves. Disconnect power before inspection, service, or cleaning, and do not operate the bleeder in damp or humid environments.

Buyer Questions
Bleeder Setup, Adapter and Fluid Questions
What Working Pressure Should I Use For AST609?
The pressure regulator is typically set around 1-1.5 bar before the device leaves the factory. During service, AST609 supports Standard Mode around 1.5-2.0 bar and Fast Mode around 2.0-2.5 bar. Do not adjust pressure excessively, because excessive pressure may damage the brake master cylinder or sealing components.
What Is The Difference Between Standard Mode And Fast Mode?
Standard Mode works around 1.5-2.0 bar and is suitable for normal brake fluid exchange. Fast Mode works around 2.0-2.5 bar and is designed for faster service when the vehicle and service conditions allow it. Select the required mode before starting the fluid exchange.
Does AST609 Need Air-Emptying Before First Use?
Yes. Air-emptying must be performed at first startup. Fill the equipment line with brake fluid and evacuate air before normal brake fluid exchange. This helps prevent air from mixing into the vehicle brake system through the equipment line.
How Many Wheels Can AST609 Service At The Same Time?
AST609 supports simultaneous brake fluid exchange for two wheels under the correct setup. If four-wheel simultaneous service is required, compare AST618, which is designed for four-wheel simultaneous oil change.
What Brake Fluid Types Are Compatible?
AST609 is applicable for DOT3, DOT4, and DOT5.1 brake fluid standards. Do not use other liquids, because liquids other than brake fluid may damage the brake maintenance device.
What Vehicles Can AST609 Fit?
AST609 includes seven adapter types for many European, American, and Asian vehicles. The adapter chart lists examples such as Mercedes-Benz, BMW, Audi, Volkswagen, Volvo, Land Rover, Jaguar, Porsche, Buick, Chevrolet, Ford, Honda, Toyota, Nissan, Dodge, Chrysler, JEEP, Hyundai, Subaru, Mitsubishi, Lexus, and other listed models. Because reservoir cap designs vary, confirm adapter fitment before ordering if the vehicle is uncertain.
What Power Supply Does AST609 Support?
Power methods are AC 110/220 V socket supply or 12 V battery supply. Confirm the selected power version, plug, transformer, and supplied cable before ordering.
What Is The Difference Between AST603, AST605, And AST609?
AST603 is an entry model with one compatible connector type and single-wheel oil change. AST605 adds more adapter coverage with three connector types while keeping a similar core setup. AST609 includes seven connector types, one 1.5L used-oil bottle, one 1L new-oil bottle, dual pressure modes, and simultaneous oil change for two wheels.
What Is The Difference Between AST609, AST612, And AST618?
AST609 includes seven adapter types and supports two-wheel simultaneous service. AST612 includes two 1.5L used-oil bottles, one 1L new-oil bottle, nine adapter types, and two-wheel simultaneous service. AST618 includes four 1.5L used-oil bottles, one integrated stainless steel oil bottle, seventeen adapter types, pulse mode and working-time settings, 360° casters, a three-section handle, and four-wheel simultaneous service.
What Should I Check Before Changing Brake Fluid?
Check each connection for leaks, inspect the connecting hose for damage, keep the new oil filler port clean, confirm that the adapter is sealed, confirm the pressure setting, and follow the vehicle manufacturer’s bleeding sequence and maximum filling pressure.
What Is Included In The AST609 Package?
Package contents: AST609 main unit, retail box, power cable, seven adapter types, new-fluid filling bottle, recovery bottle, user manual, and the listed accessories.
How Long Is The Warranty?
