Removal and installation the brake light switch sensor (Opel Astra H)

1. The switch sensor is attached to the brake pedal bracket and when the pedal is pressed, it activates the brake lights, warning other road users of the start of braking. The brake lights should be activated with a pedal travel of 15±5 mm. In addition, the switch sensor sends a corresponding signal to the ABS/EDS control module to activate the braking control process. For this reason, the precise operation and adjustment of the sensor are extremely important.

2. Disconnect the cable from the negative battery terminal (see Chapter 5).

3. Move the front seat back as far as it will go.

4. To gain access to the brake pedal, remove the lower instrument panel trim cover and the side trim cover of the center console on the driver's footwell side, as well as the air supply hose to the driver's footwell (see Chapter 11).

5. Ask an assistant to press the brake pedal and hold it in this position - the sensor contact rod should move outward. Pull the sensor locking sleeve until it stops in the direction indicated by the arrow (see accompanying illustration).



6. Press the clamps (see accompanying illustration) and remove the switch sensor from the pedal bracket. Disconnect the wiring connector from the sensor.





7. Installation is carried out in reverse order.
