2.2 Intended use
The BMA/BMB Tool (Brake Maintenance A or B model) is a rake
maintenance tool for filling and leeding hydraulic systems containing
rake fluid in motor vehicles, e.g. rake or clutch circuits. The BMA/BMB
Tool may only e used with DOT 3, DOT 4 or DOT 5.1 (glycol- ased) rake
fluid. Hydraulic fluid ased on mineral oil or DOT 5 rake fluid (silicone-
ased) is not suita le for the BMA/BMB Tool and must therefore not e
used. As rake fluid is very hydroscopic (a sor s and retains moisture),
the BMA/BMB Tool must e stored and operated in dry conditions.
For maintenance of the hydraulic system, the BMA/BMB Tool is connected
to the associated rake fluid reservoir using a suita le adapter. A
pressurised electric pump delivers new rake fluid from the BMA Tool or
BMB Tool to the rake fluid reservoir. The supply pressure can e
continuously adjusted from 0 to 2.8 ar. The rake fluid current pulsates
during the leeding phase of the hydraulic system. These fluctuations
ena le a complete leeding process, as even the smallest amounts of air
or moisture at the pipe connections are carried away.
After switching off the electric pump, the pressure in the rake fluid
reservoir reduces and the correct rake fluid level is automatically set.
If the rake fluid container is emptied to the minimum filling level, the
pump switches off automatically. This ensures that air never gets into the
hydraulic system.
