Vehicle description: school and transit buses equipped with bendix air brakes. Bendix changed the internal design of the qr1c relay valve by adding a hole in the internal diaphragm. When the hole in the diaphragm aligns with the hole in the valve body, the brake application time increases.
Dealers will replace the diaphragms with holes with solid diaphragms for the qr1c valves.
