Measuring how far the sensor projects from its
bracket towards the parking brake arm will make it
easier to fit the new one. Try to maintain this distance
when assembling.
1. Loosen the front nut (4) and pull out the sensor (5)
from the bracket.
2. Carefully remove the shrink hose (2).
3. Loosen the sensor from the cable.
4. Fit a new shrink hose over the cable.
5. Remove the rear nut (3) from the old sensor
and fit it in the same position on the new sensor.
6. Fit the shrink hose so that it covers the sensor
LEDs and goes some way over the cable.
7. Position the sensor.
8. Fit the front lock nut.
Set the distance 2 - 3 mm between the sensor and
its target surface with the parking brake active.
Before tightening, check that the parking brake arm
does not collide with the sensor when it is moved
between end positions.
