✅ Pulse Type Brake Fluid Flushing 
Utilizing innovative pulse-type fluid change technology, high-frequency pulses continuously apply pressure to not only thoroughly purge air from the lines but also powerfully flush away dirt and impurities from the inner walls of the pipes. This pulse-type system effectively prevents air bubbles from forming during the brake fluid refill process, thereby optimizing the procedure and eliminating the need for manual bleeding.

✅ Smart Monitoring & Automatic Shutdown Protection 
Built-in high-precision pressure monitoring and fluid level sensors provide real-time status tracking. The machine automatically stops filling when the new brake fluid reservoir is low, preventing air from entering the brake system. Users can adjust the pressure via a control knob within a range of 0.5–2.5 bar; if pressure cannot be established or the pump draws in air, it will automatically shut down.

✅ One-Person Operation for Effortless Brake Fluid Replacement
AST603 operates fully automatically with a single button press, allowing a single operator to complete the task without needing to press the brake pedal or rely on gravity for draining. It can replace fluid in all four wheels simultaneously. Once the operating environment is set, the entire replacement process proceeds automatically.
