Technical Specifications

Installation Guide

1. Remove the existing wheel and brake assembly to access the hub flange.
2. Clean the hub surface to ensure no debris interferes with the ring’s fit.
3. Align the Triscan 8540 25403 sensor ring onto the hub flange, ensuring it sits flush against the mounting surface.
4. Secure the ring using the supplied retaining clip or fastener as per vehicle specifications.
5. Reconnect the wheel speed sensor wiring harness to the new ring’s terminals.
6. Reinstall the brake assembly and wheel, then perform a test drive to confirm proper ABS operation.

Benefits for Vehicle Safety

The ABS Sensor Ring plays a critical role in maintaining vehicle stability during emergency braking. By accurately transmitting wheel speed data, it allows the ABS controller to modulate brake pressure on each wheel, preventing lock‑up and preserving steering control.

• Enhanced Braking Performance: Reduces stopping distances under adverse conditions.
• Improved Vehicle Control: Maintains directional stability during hard braking.
• Reliability: Robust ABS design minimizes failure rates compared to lower‑grade components.

Maintenance Tips

• Inspect the sensor ring annually for cracks or wear, especially after exposure to road salt or harsh weather.
• Keep the mounting area clean; debris can compromise the seal and signal quality.
• Replace the ring immediately if any electrical irregularities are detected during diagnostics.
