Abstract
A hydraulic master cylinder has pistons displaceable along the pivot axis of a brake pedal to apply the vehicle brakes. Motion between the pedal and the pistons is transmitted by balls located in a respective arcuate track formed partly in the pedal and partly in the respective piston. The master cylinder is particularly suitable for dual circuit brake systems. A master cylinder having a single piston is also disclosed.
