AUTOOL AST612

Product Overview

The AUTOOL AST612 brake fluid change machine is a 12V vehicle-powered pulsating brake oil exchanger designed for two-wheel oil exchange. It uses microcontroller control to accurately manage brake fluid pressure and flow, applies new pulse technology to the brake fluid pipeline, helps remove impurities, improves work efficiency, and allows one person to complete brake fluid replacement more easily.

Key Features

Key Features

AST612 focuses on portable, one-person, two-wheel brake fluid replacement with pulse exchange, 12V battery power, nine adapters, pressure release, and compact workshop operation.

Pulsating Exchange Technology

The pulse exchange process helps replace brake fluid quickly, remove impurities from the brake line, and improve service efficiency.

Single-Person Operation

One operator can complete brake fluid replacement without requiring another person to repeatedly press the brake pedal.

Powered By 12V Battery

No external mains power is required. Connect AST612 directly to the vehicle’s 12V battery for operation.

Two-Wheel Oil Exchange

Equipped with two 1.5L used oil bottles, AST612 can change brake fluid from two wheel positions at the same time.

9 Types Of Adapters

Nine adapter types help support many European, American, and Asian vehicle models.

Pressure Release Function

After replacement is complete, the machine automatically releases pressure to reduce brake fluid splash risk.

Compact And Portable

The compact body is shown as 268×210×295mm and about 4.2kg in the feature image, making it easy to move between work areas.

Practical Body Design

Side hook, top handle, and rear storage-bottle base help keep the filling hose, handle, and bottle organized during workshop use.

How It Works

How It Works

AST612 delivers new brake fluid at controlled pressure, drains used brake fluid from the calipers in sequence, reduces bubble formation during filling, and uses pressure monitoring to protect the brake fluid reservoir.

New Fluid Delivery

Brake fluid is pumped from the new fluid container and delivered to the vehicle brake fluid reservoir at specified pressure.

Wheel Caliper Drainage

Used brake fluid is drained from each wheel brake caliper in the prescribed sequence until new fluid flows out.

Bubble Prevention

Compared with traditional pressurized brake fluid bleeders, AST612 helps prevent air bubbles from forming during the filling process.

Pressure Monitoring Protection

If pressure cannot be generated or the pump draws in air, the built-in pressure monitoring system shuts down to prevent air from entering the brake fluid reservoir.

How To Use

How To Use

Connect the storage bottle, hoses, 12V battery, adapter, and recovery bottle correctly before starting the machine. The vehicle does not need to be started during operation.

Add Brake Fluid

Add new brake fluid into the storage bottle.

Connect Bottle Hoses

Connect the suction hose and pressure balancing hose to the storage bottle.

Connect 12V Battery

Connect the machine to a 12V battery using the battery clamp cable.

Connect Adapter

Connect the filling hose to the appropriate adapter, then connect it to the vehicle brake fluid reservoir.

Attach Recovery Bottle

Attach the recovery oil bottle to the brake cylinder / caliper.

Start Operation

Turn on the power switch and press the start button to begin brake fluid exchange.

Use Notes

  • No need to start the vehicle for operation.
  • Check each connection for leaks during oil change.
  • Inspect the connecting hose for damage.
  • Keep the new oil filler port clean.
  • For first use, fill the equipment tubing with brake fluid to bleed air from the tubing.
  • If air enters the equipment tubing during oil exchange, the oil exchange may fail.

Product Comparison

Product Comparison

AST612 sits between AST609 and AST618: it is more efficient than single-wheel models and more portable than AST618, but it does not provide four-wheel simultaneous service or AST618’s pulse / working time settings.

AST603 / AST605AST605 includes two more compatible connectors than AST603, while other parameters remain the same. Both include one 1L used oil bottle and deliver up to 1.6L/min.
AST609Includes seven compatible connectors, one 1.5L used oil bottle, one 1L new oil bottle, and 2.6L/min maximum flow for higher efficiency.
AST612Includes two 1.5L used oil bottles, one 1L new oil bottle, nine adapters, and supports two-wheel simultaneous brake fluid exchange.
AST618Includes four 1.5L used oil bottles, one stainless steel oil bottle, seventeen adapters, four-wheel simultaneous exchange, pulse mode, working time settings, 360° wheels, and a three-section handle.

Before You Order And Use

Before You Order And Use

Review pressure adjustment, leakage checks, hose condition, filler-port cleanliness, and brake master cylinder protection before using AST612.

Warm Tips

  • When the device leaves the factory, the working pressure of the pressure regulator is set to 1–1.5bar.
  • This setting helps ensure that the liquid storage chamber does not deform while changing fluid, thereby ensuring the tightness of the secondary sealing ring.
  • It is also feasible to exhaust or change liquid at lower working pressure by adjusting the pressure and size switch.
  • In special circumstances, higher working pressure may be used, but excessive pressure adjustment may damage the brake master cylinder of the brake system.
  • Please check each connection for leaks when changing oil.
  • Inspect whether the connecting hose is damaged before and during operation.
  • Keep the new oil filler port clean.
  • No need to start the vehicle during operation.
  • Use suitable brake fluid and avoid contaminating new brake fluid.
  • Brake fluid may damage painted surfaces; clean spills immediately.

    Autool AST612 is the clear winner when it comes to bleeding brakes it portable, small and packs power and gets the job done. Autool overall makes outstanding tool, other suppliers want to charge $400 to $3000+ for a brake bleeding machine, The AST612 I use out in the field it is my go to bleeder. Stop wasting your time and money on the higher priced items when you can go with Autool, they have super fast shipping and outstanding prices.

  9. Zenobia Albert

    Wenn man mehr als ein Auto hat, ist das Entl¨¹ften bzw. Neu f¨¹llen der Bremsen irgendwann l?stig, au?erdem dr¨¹ckt man gerade bei ?lteren Fahrzeugen die Dichtung des Hauptbremszylinders ¨¹ber den kompletten Weg, was diese nicht immer ¨¹berlebt.
    Und hydraulische Kupplungen sind damit auch ein Klacks.

    Gesamturteil: super Maschinchen, sehr empfehlenswert und mehr als fairer Preis f¨¹r diese saubere Verarbeitung und gute Technik.
