Abstract

Master and slave cylinders (10, 45) are provided interconnected by a conduit (46). The master cylinder (10) includes a piston (19) movable in a cylinder (11) which defines a pressure chamber (82) arranged to be placed under pressure by the piston (19) to operate the slave cylinder. To reduce the space required by the master cylinder, a reservoir (83) for the master cylinder is defined partly by the piston (19) and partly by the cylinder (11).
