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 Citroen 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:
- Remove the ABS sensor.
- Clean any corrosion from the sensor mounting point or guide tube.
- Inspect the sensor – replace if damaged.
- Install the new brake disc, ensuring correct air gap between ABS sensor and ABS ring.
- Test the ABS system to confirm correct operation.
- What’s in Comline’s brake disc range?
Comline’s brake disc range comprises of more than 1,350 applications. The majority of these feature an anti-corrosion coating and cover 90 per cent of European, Japanese and Korean passenger cars and LCVs.
The coated brake discs undergo a nine-stage process: pre-degreasing, first and second ultrasonic degreasing, first and second water washing, drying, coating, baking and, finally, appearance checking.
The discs are rigorously tested too – both in the manufacturing factory and within Comline’s own quality laboratory; for example, they undergo 240 hours of salt spray testing to demonstrate durability and coating corrosion resistance. Each disc is also checked for ‘run out’, thickness variation and dynamic balance.
