AUTOOL AST605 Car Pulsating Brake Oil Changer Single Clutch Slave Cylinders Brake Extractor Oil Pump Machine for all Vehicles
AUTOOL AST605 is a pulsed brake fluid exchanger that effectively avoids air bubbles during filling, optimizing or eliminating the need for manual venting compared to conventional pressurized systems. It features a powerful recovery function that quickly recovers used brake fluid. The air inlet port includes a water separation and filtering device to remove moisture from the air, preventing it from mixing with the oil and ensuring quality.
- How To Adjust Working Pressure Correctly?
- When the device is out of the factory, the working pressure of the pressure regulator is set to 1~1.5 bar, to ensure that the liquid storage chamber does not deform while changing liquid, thereby ensuring the tightness of the secondary sealing ring.
In addition, it is also feasible to exhaust or change the liquid at a lower working pressure by adjusting the pressure and the size switch.
In special circumstances, while operating under a higher working pressure, be aware of the excessive pressure adjustment, which may damage the brake master cylinder of the brake system. - Please check each connection if there is any leak when changing the oil, and whether the connecting hose is damaged, to keep the new oil filler port clean.
What Is The Difference Between Brake Oil Exchanger Tool?

AUTOOL AST605 Brake Fluid Exchange Features:
- Built-in Pressure Monitoring System: The pump for filling the brake fluid reservoir has a pressure monitoring device. You can adjust the pressure using the knob, with a range of 0.7-2.5 Bar. If pressure cannot be established or if the pump sucks in air, it will shut down automatically. The recycling bottle fits inside the machine for easy transport.
- Widely Applicable: AUTOOL AST605 is suitable for brake fluid tanks in European, American, and Asian cars. It works with almost all vehicles. This device is compatible with DOT3, DOT4, and DOT5.1 brake fluid standards.
- High Efficiency: Our main bleed kit requires only one person to operate. It allows for easy brake oil changes. The kit can change oil from four sub-pumps simultaneously. Once you set the working environment, the entire process is automatic. You don’t need to worry about being too busy.
- Optimize Advantage: Compared to traditional compression brake fluid bleeding devices, the pulsating electric brake oil exchanger avoids bubble formation during fluid addition. This optimizes the process and eliminates the need for manual bleeding. AUTOOL AST605 also has a powerful recovery function that quickly recovers used brake fluid.
- Three-Year Warranty, Lifetime Maintenance: For damage caused by non-human factors, AUTOOL promises to resend parts for free within 3 years. For any needs, feel free to contact us. We will respond within 24 hours.
How To Use AUTOOL AST605?
- Note: No need to start the vehicle for the operation.
- Raise the car to a suitable height so the drive wheels are not on the ground.
- Connect one oil pot of the device to the car brake cylinder. Loosen the exhaust screw of the brake cylinder to ensure oil flows out.
- Pour 2L of new brake fluid into the equipment from the fuel filler port. Find the matching connector to attach to the brake master cylinder.
- Connect to 12V car power and turn on the power switch button.
- Press the Vacuum Switch button.
- Press the Fuel Switch button to change the brake fluid.
- During the oil changing process, monitor the car brake oil tank. If refueling is too slow, press the acceleration switch. If it’s too fast, press the deceleration switch.
- After the oil change is completed, the used oil in the tank of the equipment must be drained clean. If it’s not emptied clean, the vacuum pump will be damaged and the oil change operation cannot be performed.
