PDWA Valve (Pressure Differential Warning Actuator) for the brake hydraulic circuit.

This valve connects the front and rear brake circuits and monitors the pressure balance between them. If one circuit loses pressure, the internal shuttle moves off-centre and closes a switch, illuminating the brake warning light to alert the driver to a hydraulic fault. For drum-brake systems without ABS.

Frequently asked questions

What is the NRC7871 PDWA valve and what does it do?
The NRC7871 PDWA (Pressure Differential Warning Actuator) connects the front and rear brake circuits and monitors the pressure balance between them. If one circuit loses pressure, the internal shuttle moves off-centre and closes a switch, lighting the brake warning lamp. It's for Defender drum-brake systems without ABS.
Which Defenders does the NRC7871 PDWA valve fit?
The NRC7871 fits the Defender 110 and 130 with drum brakes and no ABS, built up to VIN HA901219. Later ABS-equipped vehicles use a different brake pressure arrangement, so confirm your vehicle has non-ABS drum brakes and check the VIN break before ordering.
What are the signs a PDWA valve has failed?
A common sign is the brake warning light staying on after a circuit has been bled or repaired, caused by the internal shuttle sticking off-centre. The valve can also leak internally between circuits. As it's part of the brake safety circuit, have any fault checked and the shuttle re-centred properly.
