Changing brake fluid (rear brake)
•
Press the brake caliper against the brake disc in
order to force the piston back.
•
Remove cover (2) complete with rubber gaiter
and top up the level of brake fluid in the reservoir.
•
Connect the brake bleeding device to the bleed
screw on the brake caliper.
•
Open the bleed screw by half a turn.
e
Important:
Brake fluid level must not drop below the MIN mark
during the bleeding process, otherwise air will be
drawn into the brake system. Bleed the system
again if this happens.
•
Draw off brake fluid until it emerges clear and
free from air bubbles.
•
Tighten the bleed screw.
•
Installation is the reverse of the removal proce-
dure: pay particular attention to the following.
•
Before reassembling, carefully wipe the rim of
the reservoir, the rubber gaiter and the cover to
remove all traces of brake fluid.

tem has to be bled using the BMWMoDiTeC, and
the Control Units, Toolbox ABS, routine; this proce-
dure is supplementary to that described in the Re-
pair Manual.
