Abstract

The hydraulic braking system for applying a vehicle's rear brakes before its front brakes incorporates a tandem master cylinder with a primary pressure space (6) defined in a cylinder bore (2) between adjacent ends of a pedal-operated primary piston (3) and a secondary piston (4) and connected to the rear wheel brakes and a secondary pressure space (8) defined between the secondary piston (4) and a closed end (5) of the cylinder bore (2) connected to the front wheel brakes. The relative strengths of first and second return springs (10) and (11) for the pistons (3) and (4) are chosen such that fluid in the secondary space (8) cannot be pressurised until a predetermined pressure has first been generated in the primary space (6). In the construction described the second return spring (11) is pre-compressed or pre-stressed in an off position of the brakes.
