Frequently asked questions

What is a PDWA valve and what does it do?

The PDWA valve is the pressure differential warning actuator in the brake system. It sits between the front and rear brake circuits and triggers the dash warning light if pressure drops in one circuit, warning you of a leak or fault. It's a safety part on split-circuit Land Rover brakes.

Which models use this PDWA valve?

This PDWA valve fits split-circuit braking systems on the Series II and III, Defender 1983-2006 and Range Rover Classic 1971-1994. Fitment depends on the exact brake setup, so confirm your vehicle uses a PDWA valve of this type before ordering, as related models used different valves.

What are the signs the PDWA valve is faulty?

Common signs are a brake warning light that stays on or flickers, or a light that trips after bleeding the brakes. The valve can seize or leak internally with age. Because it's tied to the split-circuit warning system, a faulty PDWA valve should be sorted promptly.

Can the PDWA valve be fitted at home?

Fitting the PDWA valve is possible for an experienced DIY mechanic, but the brake system must be bled correctly afterwards and the shuttle re-centred so the warning light resets. Brakes are safety critical, so anyone unsure should have the work and bleed done by a garage.
