Comline, a leading automotive parts supplier, has released a technical bulletin tackling a frequent issue with brake discs featuring integrated ABS rings, commonly found in Citroën and Peugeot vehicles. The bulletin provides clear guidance for technicians to ensure proper installation, prevent damage, and maintain vehicle safety.
Key Highlights:
- Corrosion Issue: Rust at the ABS sensor mounting point can misalign the sensor, closing the air gap with the ABS ring.
- Warning Signs: Immediate ABS warning light activation or potential damage to the ABS ring post-installation.
- Solution Provided: Step-by-step instructions to clean, inspect, and install components correctly.
- Brake Disc Range: Over 1,350 applications with anti-corrosion coating, covering 90% of European, Japanese, and Korean vehicles.
- Rigorous Testing: Discs undergo extensive durability and performance checks, including 240-hour salt spray testing.
Understanding the ABS Sensor Issue
Brake discs with integrated ABS rings are critical for vehicle safety, but corrosion around the sensor mounting point can disrupt alignment. This issue, often seen in Citroën and Peugeot models, causes the ABS sensor to contact the ring, eliminating the necessary air gap. As a result, the ABS warning light may illuminate immediately after installation, or the ring may sustain damage, leading to costly repairs or returns.
Comline’s Step-by-Step Solution
To address this, Comline outlines a straightforward process for technicians:
- Remove the ABS sensor to access the mounting point.
- Clean corrosion from the sensor mounting or guide tube.
- Inspect the sensor and replace it if damaged.
- Install the new brake disc, ensuring the correct air gap between the sensor and ABS ring.
- Test the ABS system to verify proper functionality.
This approach minimizes errors, protects components, and ensures reliable ABS performance.
Comline’s Extensive Brake Disc Range
Comline’s brake disc portfolio includes over 1,350 applications, covering 90% of European, Japanese, and Korean passenger cars and light commercial vehicles (LCVs). Most discs feature an anti-corrosion coating, applied through a meticulous nine-stage process: pre-degreasing, ultrasonic degreasing (twice), water washing (twice), drying, coating, baking, and appearance checking. This coating enhances durability and resistance to harsh conditions.
Rigorous Testing for Quality Assurance
Comline prioritizes quality through extensive testing. Each brake disc undergoes 240 hours of salt spray testing to confirm corrosion resistance. Additional checks for run-out, thickness variation, and dynamic balance ensure consistent performance. Testing occurs both at the manufacturing facility and in Comline’s dedicated quality laboratory, guaranteeing reliability for technicians and drivers alike.
