Land Rover Part Number: LR055940 - Antilock Brake Modulator Valve
LR055940 is an Antilock Brake Modulator Valve fitted to the 4-wheel anti-lock braking system. The valve regulates hydraulic pressure within the modulator assembly and directs pressure to individual wheel circuits. As a hydraulic control element, it is signalled by the ABS control unit to change pressure to specific wheel circuits by opening and closing internal valves and solenoids. This controlled modulation prevents wheel lock-up under heavy braking and supports vehicle stability by allowing brake force to be quickly released and reapplied at a single wheel when slip is detected. The valve operates alongside wheel speed sensors and the ABS electronic control module. Fitted to Defender 2007-2016 models, the component must match the vehicle configuration so the ABS system maintains correct pressure distribution and braking response.
