Abstract
An adaptor or retrofit unit which is placeable between a pipe bracket and the service portion of a brake control valve which includes brake pipe passage, brake cylinder passage, auxiliary reservoir passage, emergency reservoir passage and an exhaust retainer passage which interconnects the corresponding ports of the pipe bracket and the service brake portion and electrically controlled valves. A first electrically controlled valve selectively controls the connection of the brake pipe passage to a venting port for applying the brakes. A second electrically controlled valve interconnects the brake pipe passage and the emergency reservoir passage for release of the brakes. A third electrically controlled valve selectively connects the auxiliary reservoir to a vent port for releasing a stuck brake. A fourth electrically controlled valve selectively controls the exhaust passage connected to the retainer for gradually releasing the brake.
