The brake system on a Volvo 1800 is a dual circuit system with disc brakes on the front wheels and drum brakes on the rear. The system is provided with a tandem master cylinder and a direct operating servo cylinder.
The principal for the dual circuit system is that both front wheels are connected to a rear wheel, that is, should one of the systems should cease to function, there is always brake power for both front wheels and a rear wheel.
The delivery lines to the rear wheels are fitted with relief valves which prevent involuntary locking of the rear wheels.
The system also includes a warning lamp mounted to the left of the rpm gauge. The warning lamp lights if one of the circuits does not function during braking. The lamp also indicates when the handbrake is applied.
