Abstract
A master cylinder includes a pressure cylinder and a pressure-generating piston movable therein. The cylinder is closely surrounded over part of its length by a separate reinforcing member in the form of a sleeve which acts to prevent significant expansion of the cylinder under the effect of internally applied pressure. In the example shown, the pressure cylinder forms part of an integral moulding which includes a fluid reservoir.
