Haldex AQ960505 2S/1M ABS Relay Valve Kit Trailer ABS Control

Haldex AQ960505 is a 2S/1M trailer ABS relay valve kit designed for commercial trailer air-brake systems. The assembly combines the ABS electronic control function and pneumatic relay-valve operation into an integrated unit, providing a replacement solution for compatible trailer Anti-Lock Braking System configurations.

The 2S/1M designation refers to an ABS configuration using two wheel-speed sensors and one modulator. During braking, the system monitors wheel-speed information and can modulate air pressure when necessary to help prevent wheel lockup. Proper ABS operation helps maintain trailer stability and directional control during hard braking and low-traction conditions.
