Key Features<\/div>\n

Key Features<\/h2>\n

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.<\/p>\n <\/div>\n\n

\n
\n

Pulsating Exchange Technology<\/h3>\n

The pulse exchange process helps replace brake fluid quickly, remove impurities from the brake line, and improve service efficiency.<\/p>\n <\/article>\n

\n

Single-Person Operation<\/h3>\n

One operator can complete brake fluid replacement without requiring another person to repeatedly press the brake pedal.<\/p>\n <\/article>\n

\n

Powered By 12V Battery<\/h3>\n

No external mains power is required. Connect AST612 directly to the vehicle\u2019s 12V battery for operation.<\/p>\n <\/article>\n

\n

Two-Wheel Oil Exchange<\/h3>\n

Equipped with two 1.5L used oil bottles, AST612 can change brake fluid from two wheel positions at the same time.<\/p>\n <\/article>\n

\n

9 Types Of Adapters<\/h3>\n

Nine adapter types help support many European, American, and Asian vehicle models.<\/p>\n <\/article>\n

\n

Pressure Release Function<\/h3>\n

After replacement is complete, the machine automatically releases pressure to reduce brake fluid splash risk.<\/p>\n <\/article>\n

\n

Compact And Portable<\/h3>\n

The compact body is shown as 268\u00d7210\u00d7295mm and about 4.2kg in the feature image, making it easy to move between work areas.<\/p>\n <\/article>\n

\n

Practical Body Design<\/h3>\n

Side hook, top handle, and rear storage-bottle base help keep the filling hose, handle, and bottle organized during workshop use.<\/p>\n <\/article>\n <\/div>\n\n

How It Works<\/div>\n

How It Works<\/h2>\n

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.<\/p>\n <\/div>\n\n

\n
\n

New Fluid Delivery<\/h3>\n

Brake fluid is pumped from the new fluid container and delivered to the vehicle brake fluid reservoir at specified pressure.<\/p>\n <\/article>\n

\n

Wheel Caliper Drainage<\/h3>\n

Used brake fluid is drained from each wheel brake caliper in the prescribed sequence until new fluid flows out.<\/p>\n <\/article>\n

\n

Bubble Prevention<\/h3>\n

Compared with traditional pressurized brake fluid bleeders, AST612 helps prevent air bubbles from forming during the filling process.<\/p>\n <\/article>\n

\n

Pressure Monitoring Protection<\/h3>\n

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.<\/p>\n <\/article>\n <\/div>\n <\/section>\n\n

\n
\n
How To Use<\/div>\n
