Warning valve Volvo 740/760

A brake warning lamp that lights up can point to a pressure difference between the circuits – and the warning valve sits at the heart of that function. When it senses that one brake system is losing pressure, the piston moves the contact and triggers the alarm. Leaking seals around the valve or a worn contact set are common things to check when the lamp comes on without an obvious cause.

This category gathers the parts for the warning valve on the 740/760: O-rings, seals, contact set and the warning valve itself. Since all 700 variants have disc brakes all round, the condition of the seals should be checked at every operation on the main brake lines, so that no moisture leakage disturbs the pressure sensing.
