REMOTE TRAILER BRAKE ACTIVATOR
First Claim
1. A device for use with the air braking system of a vehicle of the type in which spring operated brakes are countered by compressed air, comprising a housing containing a pneumatic circuit for inclusion in the air braking system of the vehicle, couplings for connecting the pneumatic circuit to the braking system of the vehicle, valve means in the circuit to admit a compressed air supply in order to both charge the circuit and the braking system and to discharge the circuit and the braking system, phone signal receiving means capable of operating the valve means to both open and close the valve means thereby charging and discharging the air braking system.

Abstract
A device for use with the air braking system of a vehicle of the type in which spring operated brakes are countered by air, has valves which charge and discharge the air storage tank of a trailer and an electronic receiver which switches the valves in response to phone and GPS signals. Discharge can proceed at two different rates in order to slow the trailer initially if the signal to brake is received while the trailer is travelling. The electronic receiver is also operable by a handheld signal generation in order to release the brakes and resume trailer travel.
