Brake balance system maintenance

• The brake force distribution is shown in the MoTeC–Display
(BBIAS) in practice mode
• The adjustment range is from -7 to +7
Pay attention when changing potentiometer:
The potentiometer is preset to "0"
•
• First remove the transport lock and only adjust the potentiometer
when the complete set is fitted to the car and the shaft is
mounted to the centralized balance bar
• When doing maintenance work on the balance bar it must be set
in the centre position before mounting the adjustment shaft.
• Afterward set the potentiometer in the MoTeC display to "0"
• Do not rotate more than +7 and -7 on the display (the
potentiometer does not have a rotation limit and would otherwise
be damaged).
• Set unfitted potentiometers to "0" with the MoTeC system before
fitting
The brake balance system is comprised of many moving parts. In general
all joints should be free of friction and no parts should be preloaded when
fitted
The following parts in the system should be cleaned and re-greased
regularly:
