A fuel tank vapor control apparatus controls the flow of liquid and vapor fuel through an aperture in a fuel tank (16). The fuel tank vapor control apparatus includes a vent housing (12) mounted in the aperture (34) and formed to include a vent inlet (13) and a vent outlet (36), the vent housing (12) defining a vent path for communicating vapor fuel from the fuel tank between the vent inlet and the vent outlet. The apparatus also includes a valve (48) movable in the vent housing between a blocking position for blocking flow of liquid and vapor fuel from the fuel tank between the vent inlet and the vent outlet along the vent path and a venting position allowing flow of vapor fuel between the fuel tank and the vent outlet along the vent path. A labyrinthine member (140) is also included, being disposed between the fuel tank and the vent path for discriminating fuel vapor from liquid fuel so as to block liquid fuel from the vent path.

A rotor for a disc brake assembly includes a centrally disposed hub and at least one friction surface disposed annularly about the hub, the friction surface including a single continuous spiral groove disposed between the hub and an outer radial edge of the rotor, the single continuous spiral groove including a first portion wherein the groove is disposed radially side-by-side relative to itself and concentrically about the hub with each adjacent segment of the first portion of the groove being spaced from itself by a first predetermined distance, the single continuous spiral groove also including a second portion wherein the groove is disposed radially in side-by-side relation relative to itself and concentrically about the hub with each adjacent segment of the second portion of the groove being spaced from itself by a second predetermined distance which is different from the first predetermined distance to improve braking of the rotor.
