[ABS] Adjusting front sensor gap

Marking sensor wheel

•

Take load off front wheel/lift clear of ground.

•

Attach dial gauge holder (1), BMW No. 00 2 500,

ference.

•

Using a paint pencil, make a permanent mark at 
the point where the sensor is farthest away from 
the sensor wheel (arrow).

e

 Caution:

If parts are replaced (brake disc etc.) and a used or 
previously marked sensor wheel is installed, the 
sensor ring must be measured and marked again.
