Abstract
A reservoir assembly for a vehicle hydraulic braking system includes two chambers (,) for the storage of hydraulic fluid. The reservoir assembly is provided with a structure for increasing the effective volume of one of the chambers (,), for example a bellows (,) or a bucket (,), and which may be operable in conjunction with the fitting of a filler cap (,) to seal a filler opening (,) for that chamber. This enables a volume of fluid to be accommodated in a chamber of increased volume, thereby substantially eliminating the possibility of volume in excess of a given volume from overflowing from the chamber (,). When the reservoir assembly is installed in a vehicle braking system of a brake-by-wire electro-hydraulic type (EMB) having a first power circuit (,), and a second back-up hydrostatic circuit (,), the one chamber (,) supplies fluid to the hydrostatic circuit, and the other chamber (,) supplies fluid to the power circuit.
