Provia’s double diaphragm spring brake actuators (DDSB) comprise spring brake and service brake chambers. Air pressure applied to the service chamber is converted into a mechanical output. Via the parking chamber, mechanical braking force holds the vehicle in the parked position. Additionally, the actuator contains a physical release mechanism to free the parking brake in the event of a brake failure.
Spring brake actuators from ProVia are a cost-effective alternative to OEM parts, backed by a WABCO guarantee of quality.
