Abstract
A master cylinder for a dual hydraulic braking system has two pistons arranged end-to-end in respective bore sections, each piston having sealing valves which close off communication between front and rear brake circuits and respective reservoirs when displaced by operation of a brake pedal to cause pressurization of respective compression chambers connected to the brake circuits. This invention provides two seals in the inner piston between the two compression chambers and an auxiliary chamber defined between these seals into which small quantities of brake fluid escape in the event of leakage from either compression chamber to give visual warning of such leakage.
