  "textContent": "A system for controlling a parking brake in a vehicle includes first and second electropneumatic valve modules disposed between a fluid source and a wheel brake on the vehicle. The valve modules include first and second solenoids, respectively, movable between a delivery state allowing fluid flow between supply and delivery ports on the valve module and an exhaust state allowing fluid flow between delivery and exhaust ports on the valve module. A brake controller transmits a first control signal to the first solenoid, the first control signal configured to position the first solenoid in one of the delivery and exhaust states. A secondary control circuit generates, responsive to a first feedback signal indicative of the state of the first solenoid, a second control signal configured to position the second solenoid in one of the delivery and exhaust states.",
