How To Choose<\/div>\n

How To Choose<\/h2>\n

Choose your AST model by service volume, power supply, number of wheels serviced at the same time, connector coverage, portability, and whether pulse \/ working time settings are required.<\/p>\n <\/div>\n\n

\n
\n

Need Portable Service?<\/h3>\n

Choose AST603 or AST605 if compact size, easier movement, and single-wheel brake fluid service are the priority.<\/p>\n <\/article>\n\n

\n

Need Two-Wheel Efficiency?<\/h3>\n

Choose AST609 or AST612 for simultaneous brake fluid replacement on two wheels. AST609 is available in 110\/220V or 12V versions, while AST612 is a DC12V vehicle-mounted style model.<\/p>\n <\/article>\n\n

\n

Need Four-Wheel Service?<\/h3>\n

Choose AST618 for simultaneous four-wheel brake fluid replacement. AST612 can be expanded for four-wheel service with two additional fluid reservoirs, but AST618 is the better native four-wheel option.<\/p>\n <\/article>\n\n

\n

Need Car Battery Power?<\/h3>\n

Choose AST612 or AST618 when you need a DC12V model that can connect directly to the vehicle battery. Confirm the ordered version if you are considering AST609 with 12V power.<\/p>\n <\/article>\n\n

\n

Have A Busy Workshop?<\/h3>\n

Choose AST618 for workshops that frequently service multiple vehicles. It supports four brake calipers, 17 connector types, pulse settings, working time settings, 360\u00b0 casters, and a three-section telescoping handle.<\/p>\n <\/article>\n\n

\n

Need Pulse And Time Settings?<\/h3>\n

Choose AST618. Among the listed AST models, only AST618 supports pulse settings and working time settings.<\/p>\n <\/article>\n <\/div>\n <\/section>\n\n
