Checking the function of the automatic linkage adjuster
1. Remove the rubber stopper cap.
2. Slacken the adjusting screw (arrow) with a
ring spanner approx. ¾ of a turn anti-
clockwise. There must be a free travel of at
least 50 mm for a lever length of 150 mm.
3. Actuate the brake lever several times by
hand. This should cause a smooth automat-
ic readjustment; it should be possible to
hear the coupling engaging and, on the
back stroke, the adjusting screw should turn
clockwise slightly.
4. Refit the stopper cap.
5. Lubricate with BPW ECO_Li91 special high
melting point grease.

voir and clean the reservoir if there are
signs of dirt deposits.
