Electro-hydraulic braking systems

An electro-hydraulic braking system including at least one electrically operated actuator which is provided in a brake line between a pressure source of hydraulic fluid and a brake, operation of said electrically operated actuator selectively connecting and disconnecting said brake to said pressure source, and wherein at least one pressure sensor is arranged to sense fluid pressure in a part of said braking system said system further including a housing having at least three discrete housing portions, a first portion containing electrical drive circuitry for said actuator, a second portion containing hydraulic fluid passages to and from said electrically operated actuator, and a third portion housing a plurality of pressure sensors, in which on assembly of said housing electrical contacts from said pressure sensors in said third portion provide a connection between said pressure sensors and said electrical drive circuitry contained in said first portion, and a respective hydraulic fluid passage extending from each of said pressure sensors in said third portion provides a connection between said pressure sensors and corresponding hydraulic fluid passages in said second portion.
