REMOTE TRAILER BRAKE ACTIVATOR

摘要

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 generator in order to release the brakes and resume trailer travel.
