Why does ABS frequently engage during low-speed braking?

[McMia]

Reasons for ABS false engagement during low-speed braking are as follows: Reason 1: The sensing part of the ABS wheel speed sensor is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding vehicle speed signal. This prevents the ABS computer from determining the vehicle speed and the wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt from the wheel speed sensor and adjust the gap between the wheel speed sensor and the signal ring to restore normal function. Reason 2: Poor signal quality due to loose connections between system lines or poor contact of the ABS relay can cause system malfunction. The most common issue is a loose connection of the wheel speed sensor wiring, which leads to faults. In such cases, the ABS computer's fault memory will also indicate poor wheel speed sensor signal quality. Solution: Check the line connections and reconnect any loose parts.
