Comline reveals fix for common installation issue on ABS rings and sensors

• Comline has issued a new technical bulletin – designed to address a common fitment issue relating to brake discs with integrated ABS rings. These are prevalent on Citroën and Peugeot models.

Comline’s brake disc range includes many applications with factory-fitted ABS rings; however, technicians have reported issues with ABS sensor alignment when fitting them – usually due to corrosion.

Corrosion around the ABS sensor mounting point can push the sensor out of place; therefore, when a new disc is fitted, this closes the required ‘air gap’ between the ABS sensor and ABS ring – causing them to touch.

Warning signs and symptoms

• The ABS warning light will appear immediately after the brake disc is installed

• The ABS sensor may damage the ABS ring on the new disc

Comline’s recommended solution

To ensure a correct installation, avoid damage or returns, follow these steps:

1. Remove the ABS sensor.

2. Clean any corrosion from the sensor mounting point or guide tube.

3. Inspect the sensor – replace if damaged.

4. Install the new brake disc, ensuring correct air gap between ABS sensor and ABS ring.

5. Test the ABS system to confirm correct operation.
