Modern service units are required for changing the brake fluid on modern vehicles with electronic brake systems. Thanks to its innovative technology of "Electronic pressure control" with variable and preset pressure stages, as well as the integrated suction device, the new ATE FB 30S is the benchmark for brake filling and bleeding units.

With its central ergonomic operating panel the new ATE FB 30S is controlled between the functions suction as well as filling/bleeding. Signal lamps show the function selected. All functions are arranged clearly on the operating panel.

There are three pressure stages available for filling, flushing and bleeding the brake system:  0.4/1.0/2.2 bar. There is also a variable pressure setting of 0.4–3.5 bar available. A manometer enables the pressure selected to be checked.

Modern low-viscosity brake fluids available make great demands on the safe function of a brake filling and bleeding unit. During development of the ATE FB 30S, great value was placed on the safe function with all standard DOT3 and DOT4 brake fluids. The ATE FB 30S brake filling and bleeding unit works directly from brake fluid cans with 5, 20 and 30 liters capacity which are secured in the unit by means of a retainer. There is no longer any need for the time-consuming transfer of brake fluid. Alongside the ATE brake fluid cans, other cans available from retailers can also be used. A special holder ensures that the suction lance is fitted firmly in the can. There is a special bleeding valve integrated in the rubber sealing cone which only allows air to enter the can when brake fluid is being removed. This prevents air being drawn into the can in an uncontrolled way. If the brake fluid can becomes empty, the ATE FB 30S is switched off automatically in order to guarantee that no air gets into the brake system. A clear acoustic signal and signal lamp indicate that the can needs changing.

Professional brake fluid changing also includes cleaning the fluid reservoir. For this, the old and soiled brake fluid is extracted from the fluid reservoir. An integrated, independent and especially robust pump is used for extracting the used brake fluid. Even difficult-to-access reservoirs are easy to empty using the extendable coil hose (around 3 meters long). A filter integrated into the suction hose protects the pump from coarse dirt particles. The extracted brake fluid is collected in a transparent drain bottle which has a capacity of about 2.2 liters. This is matched to the ATE disposal system and can be emptied easily. Conventional emptying is also possible via the screw cap.

Practical features of the ATE FB 30 S are the filling hose and power cable holders on the side, as well as holders for three bleeding spigots. There is a practical storage tray on the unit for depositing small parts or tools. Large wheels at the rear combined with the ergonomic handle make convenient and safe maneuvering of the ATE FB 30S possible.
