Key Features
Air-Powered Flow with Used-Fluid Recovery
Pulsating Fluid Exchange
Compared with conventional pressurized brake fluid bleeding, the pulsating exchange method helps reduce bubble formation during filling and can reduce the need for repeated manual venting.
One-Person Operation
After the brake fluid bottle, filling hose, recycle bottle, connector, and pressure setting are prepared, one operator can complete the brake fluid exchange process more efficiently.
Gauge-Guided Pressure Control
The filling pump includes pressure monitoring. Use the pressure knob and gauge to control working pressure during brake fluid replacement.
Automatic Protection Logic
If pressure cannot be established or the pump sucks in air, the machine can shut down automatically to help protect the system during operation.
Used Brake Fluid Recovery
The recovery function collects used brake fluid quickly. The recycle bottle can be placed inside the machine body for easier carrying and storage.
Moisture Filtering At Air Inlet
The air inlet includes a water separation and filtering device to help remove moisture from the air and reduce the chance of moisture mixing with the brake fluid.
Brake Fluid Compatibility
AST605 is compatible with DOT3, DOT4, and DOT5.1 brake fluid standards. Always follow the vehicle manufacturer’s required brake fluid type.
One-Person Pressure Control
AST605 supports one-person pulsating brake fluid exchange with an adjustable pressure knob and a gauge for monitoring working pressure.
Used-Fluid Bottle Storage
The recovery function collects used brake fluid, and the corrosion-resistant recycle bottle fits inside the machine body for carrying and storage.
Accessible Workshop Connections
Quick connectors, a hose hook, and the pressure gauge and knob keep setup and pressure adjustment within reach.
Vehicle Coverage
Suitable for many European, American, and Asian vehicles when the correct adapter is used. Confirm compatibility for special reservoir designs before ordering.
3 Years Warranty Support
Main unit: 3-year warranty. Standard accessories: 1-year warranty. Warranty Policy.
Safe Use
Dry the Air, Seal the Reservoir and Limit Pressure
Use Safe Working Pressure
The AST605 supports adjustable pressure, while the factory reference working pressure is around 1-1.5bar. Avoid unnecessary high pressure because excessive pressure may damage the brake master cylinder or brake system parts.
Adjust Pressure Gradually
The pressure regulator can be used for lower-pressure bleeding or fluid exchange when needed. Increase pressure carefully and monitor the pressure gauge during operation.
Check For Leaks First
Before changing brake fluid, check every connection point for leakage and inspect hoses for damage. Keep the new oil filler port clean.
Prevent Air In The Line
During first use, fill the equipment line with brake fluid to evacuate air before service. This helps prevent air from mixing into the vehicle brake fluid line.
Vehicle Coverage
Suitable for many European, American, and Asian vehicles when the correct adapter is used. Confirm compatibility for special reservoir designs before ordering.
Prime the Fluid Line
Fill the delivery line with the specified brake fluid and remove air before connecting it to the vehicle.
Seal the Reservoir
Choose the matching reservoir adapter and check the cap and hose connections for leaks before building pressure.

Buyer Questions
Bleeder Setup, Adapter and Fluid Questions
What Working Pressure Should I Use For AST605?
The factory reference working pressure is around 1-1.5bar to help prevent deformation of the liquid storage chamber and keep the secondary sealing ring tight. AST605 supports adjustable pressure, but avoid unnecessary high pressure because excessive pressure may damage the brake master cylinder or other brake system components.
Can AST605 Change Brake Fluid From Four Wheels At The Same Time?
No. AST605 is a single-wheel oil change model with 1pc brake caliper service. If you need two-wheel simultaneous service, compare AST609 or AST612. If you need four-wheel simultaneous brake fluid exchange, choose AST618.
What Brake Fluid Types Does AST605 Support?
AST605 is compatible with DOT3, DOT4, and DOT5.1 brake fluid standards. Always use the brake fluid type required by the vehicle manufacturer.
Do I Need To Start The Vehicle During Operation?
No. The vehicle does not need to be started during AST605 operation. Raise the vehicle safely, connect the hoses and adapter correctly, and operate the machine according to the service procedure.
Why Should I Fill The Equipment Line With Brake Fluid Before First Use?
Filling the line with brake fluid during first use helps evacuate air from the equipment line. This reduces the risk of air mixing into the vehicle brake fluid line during exchange, which could affect braking performance.
What Should I Check Before Changing Brake Fluid?
Check each connection for leakage, inspect whether any connecting hose is damaged, confirm the correct adapter is installed, keep the new oil filler port clean, and make sure the used-oil recovery path is connected correctly.
What Should I Do After The Oil Change Is Completed?
Drain the used oil in the equipment tank completely after service. If the used oil is not emptied, the vacuum pump may be damaged and the oil change operation may not be performed correctly next time.
Does AST605 Support 110V And 220V?
Order the AST605 voltage version that matches the workshop supply, then verify the voltage on the selected unit’s label before connection.
Which Connectors Are Included With AST605?
AST605 includes 3 compatible connector types. Adapter examples include #1 for many European, American, and Asian vehicle brands, #6 for Toyota series, and #16 for Tesla. Confirm compatibility before ordering if your vehicle uses a special brake fluid reservoir connector.
Which AST Brake Fluid Bleeder Should I Choose?
- Choose AST605 if you need a compact pulsating brake fluid bleeder with 3 connector types and single-wheel oil change.
- Choose AST609 if you need 7 connector types and two-wheel simultaneous service.
- Choose AST612 if you need DC12V operation and 9 adapter types.
- Choose AST618 if you need 17 adapter types, four-wheel simultaneous service, pulse settings, working time settings, wheels, and a telescoping handle.
How Long Is The Warranty?
