Fluid reservoir system for a master cylinder

A fluid reservoir system ( 10 ) for a master cylinder ( 12 ) having first and second fluid chambers each with associated pistons, the system comprising a main reservoir ( 16 ); a first secondary reservoir ( 18 ) for mounting on the master cylinder to supply fluid to the first fluid chamber; a second secondary reservoir ( 18 ) for mounting on the master cylinder to supply fluid to the second fluid chamber; a first fluid pipe ( 22 ) fluidly connecting the main reservoir with the first secondary reservoir; and a second fluid pipe ( 24 ) fluidly connecting the main reservoir with the second secondary reservoir; wherein the first secondary reservoir has a fluid capacity which is substantially equal to, or greater than, the capacity of fluid required by the first fluid chamber during full stroke of the associated master cylinder piston; and wherein the second secondary reservoir has a fluid capacity which is substantially equal to, or greater than, the capacity of fluid required by the second fluid chamber during full stroke of the associated master cylinder piston. Allows remote location of the main reservoir from the master cylinder.
