The AUTOOL AST609 is a pulsating brake fluid changer for brake and clutch fluid service on many European, American, and Asian vehicles. It supports adjustable pressure, one-person operation, two-wheel simultaneous brake fluid exchange, used-fluid recovery, seven reservoir adapters, and DOT3, DOT4, and DOT5.1 brake fluid service.
Brake fluid service affects braking safety. Confirm pressure, fluid type, hose condition, adapter sealing, and first-use air emptying before starting the AST609 brake fluid exchange process.
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.
Keep New Fluid Port Clean
Keep the new brake fluid filler port clean. Do not allow dust, water, old oil, or debris to enter the new fluid supply.
Use Brake Fluid Only
Use the AST609 only for brake and clutch brake-fluid service. Other liquids may damage the brake maintenance device.
Safety Reminder
Brake fluid is toxic. Avoid skin and eye contact, and wear suitable safety goggles and protective gloves.
Only trained users should operate brake maintenance equipment.
Follow the vehicle manufacturer’s brake bleeding sequence, maximum filling pressure, and service instructions.
Disconnect power before inspection, service, or cleaning of the device.
Do not use the machine if hoses, cables, connectors, or the machine body are damaged.
Do not operate the brake fluid bleeder in damp or humid environments.
Key Features
Key Features
AST609 combines pulsating fluid exchange, pressure adjustment, used-oil recovery, multiple adapters, water separation, and portable workshop handling for efficient brake and clutch fluid maintenance.
Dual Pressure Modes
Standard Mode works around 1.5-2.0 bar, while Fast Mode works around 2.0-2.5 bar. Select the required mode before starting the brake fluid exchange.
One-Person Operation
The pulsating electric brake oil exchanger reduces repeated manual bleeding work and allows one operator to complete the service more efficiently.
Two-Wheel Simultaneous Service
AST609 supports simultaneous brake fluid exchange for two wheels under the correct setup, improving efficiency compared with single-wheel models.
Used Fluid Recovery
The machine can recover used brake fluid during service, helping keep the work area cleaner and making fluid replacement easier to manage.
Water Separation Filter
The water separation filter in the air inlet helps remove moisture from air before it mixes with the oil path, supporting cleaner service quality.
Pressure Monitoring
The front pressure gauge displays working pressure in real time, and the pressure adjustment knob helps the operator control the service pressure.
Portable Workshop Design
The compact body includes a handle, filling-hose hook, pressure gauge, indicators, fuse, power interface, and a bracket for the 1L corrosion-resistant filling bottle.
Low Oil Protection
Low oil protection is supported, helping reduce the risk of running the equipment without enough brake fluid in the supply bottle.
Warranty And Support
AUTOOL provides 3-year support for eligible non-human damage cases, with assistance for adapter fitment, pressure setup, operation, and troubleshooting.

How To Use
How To Use
Perform air-emptying during first startup, then connect the correct adapter, new-fluid bottle, filling hose, and recovery bottle before starting brake fluid exchange.
Prepare The Machine
Place the brake fluid exchanger firmly on a flat surface. Make sure the filling hose is not under mechanical tension when the vehicle is lifted.
Fill The New-Fluid Bottle
Unscrew the filling cover, pour new brake fluid into the bottle, and insert the suction hose and pressure balance hose down to the bottom of the bottle.
Perform First-Use Air Emptying
Before first use, connect the suction hose into the brake fluid filling bottle, turn on the equipment, and drain brake fluid through the adapter into the recovery bottle until air is removed.
Connect The Vehicle Adapter
Select the correct brake-fluid reservoir adapter, connect the filling hose to the reservoir through the adapter, and check that the adapter is sealed securely.
Connect The Recovery Bottle
Connect the recovery bottle to the brake fluid sub-cylinder according to the vehicle manufacturer’s bleeding sequence.
Start Fluid Exchange
Connect power, select the correct pressure mode, press the start button, and wait until the fluid exchange is completed and clean fluid flows steadily without air bubbles.

Contact AUTOOL Store before ordering if you need to confirm adapter fitment, power supply version, brake fluid type, pressure mode, first-use air emptying, or model selection.
These answers cover pressure setup, dual pressure modes, first-use air emptying, two-wheel service, brake fluid compatibility, adapters, package contents, safety checks, and AST model selection.
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.
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.
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.
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.
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.
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.
The product materials show AC 110V / 220V socket supply and 12V battery power supply methods. Confirm the selected power version, plug, transformer, and included cable before ordering.
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.
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.
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.
