with Optimoly TA or Plastilube. If new

center and insert it. Make sure that
spreader springs engage correctly

7. Press the warning contact(s) Into the pad
plate in the correct positions. Secure the
warning contact lead to the brake caliper
and, if two warning contact leads are pre-
sent (from 1989 models on), to the cross
spring as well.
Note
If tolerances are unfavorable, the spreader
spring may have to be disengaged again to
do this.
8. With the car standing still, depress the brake
pedal firmly several times, so that the brake
pads adopt a position ready for later opera-
tion. After this, check brake fluid level in the
reservoir and add more fluid if necessary.
Running in the brake pads
New brake pads need to be used for about
200 kilometers before they develop their op-
timum friction and wear characteristics. During
this time, avoid full brake applications from
high speeds unless an emergency arises.
