[Also in Division F2] A cycle brake lever 54 pivoted at 56 may be moved to push a piston 48 inwardly and transfer fluid so expelled, through a flexible tube 38 into a cylinder 22 connected via a cylinder extension 26 and a piston-rod 24 to spring returned calliper brake arms hinged at 18. A fluid filling plug (60), Figs. 1 and 4 (not shown) may be provided in the pipe 38, and the cylinder 22 may be replaced by any other type of mechanism capable of expansion and contraction by fluid injection, e.g. a bellows element. |
