PNEUMATICALLY CONTROLLED HYDRAULIC TRAILER BRAKE SYSTEM Abstract of the Disclosure Disclosed herein is a trailer brake control system com- prising a trailer-mounted servo-motor type booster in direct operating connection, e.g., by hydraulic lines, with the trailer wheel brakes, an electrical transducer and signal amplification apparatus mounted on the towing vehicle, and a solenoid synchronizing valve for controlling the booster operably posi- tioned between the signal amplification apparatus and the booster for translating electrical signals of varying magnitude into correspondingly varying brake action. The system enables the operator of a tow vehicle and trailer combination to operate the trailer brakes with power-applied effort which is propor- tional to manual pedal effort applied to the braking system of the tow vehicle, or optionally, to operate the trailer brakes independently of the tow vehicle brakes to any extent desired through manual control of the signal amplification apparatus.
