Hydraulic fluid supply device for motor vehicle

The hydraulic fluid feed system (1) consists of a first reservoir (2) with a filler hole and cap (23), and a second reservoir (4) with an intake (41) and an outlet connected to the fluid, e.g. braking circuit. The two reservoirs are connected by a flexible tube (6), with the first reservoir having a level indicator (24) and the second, fed by gravity from the first, having a simple contact level sensor.
