The Bendix® E‑10P™ dual brake valve is similar to the E‑8P dual brake valve except that a metal coil spring housed in an upper body assembly replaces the rubber spring (27) used in the E‑8P valve. The use of a metal coil spring (and the upper body assembly) provides greater treadle travel and, therefore, provides the driver with a less sensitive “feel” when making a brake application. The E‑10P dual brake valve is generally used on buses, where smooth brake applications contribute to passenger comfort.
