The issue
Certain trucks equipped with Bendix SR-7 spring brake modulating valve may experience an internal air leak if the check valve fails to seat. This may cause a delay in the application of the parking spring brakes leading to an unintended vehicle rollaway. Correction: Dealers will replace the Bendix SR-7 valve and the Parker single check valve.
Description (français)
Certains camions équipés de modulateur de frein à ressort Bendix SR-7 pourraient subir une fuite d'air interne si le clapet anti retour ne s'appuyait pas contre son siège. Cela pourrait causer un délai dans le serrage des freins à ressort de stationnement résultant en un déplacement non voulu du véhicule. Correction : Les concessionnaires devront remplacer le modulateur Bendix SR-7 et le clapet de non retour Parker.
