The hydraulic system, containing master and slave cylinders, has a pressure pipe between them made from two or more segments having different wall thicknesses. The pipe can be made from a plastic material in one piece, partly from plastic and partly from metal, or from a composition material with a polymer lining. The composition material can comprise a layer of an elastic material and a layer of a traction resistant material such as woven metal and/or glass and/or carbon and/or polymer fibres. Variants of the design can comprise two pipes (31, 32) linked side by side along an axial line or by a connecting rib, or coaxial pipes one inside another.
