The issue

Certain vehicles equipped with Neway ADZ Tridem rear suspension may not comply with the brake timing requirements of Canada Motor Vehicle Safety Standard (CMVSS) 121 - Air Brake Systems. The brake control airline between the two relay valves is plumbed with a 3/8" airline but should be plumbed with a 1/4" line to balance the service brake application timing and meet the requirement of the standard. An oversized airline could cause a delay in brake activation and increase stopping distances, which could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will update and modify the brake piping of the air brake system.

Description (français)

Certains véhicules munis d'une suspension arrière pour essieu tridem Neway ADZ pourraient ne pas satisfaire aux exigences de la norme de sécurité des véhicules automobiles du Canada (NSVAC) 121 - Systèmes de freinage à air comprimé, relatives à l'équilibrage de la pression de freinage. La conduite d'air de la commande de freinage entre les deux valves-relais est une conduite de 3/8 po, mais devrait être une conduite de 1/4 po pour pouvoir équilibrer le serrage du frein de service et satisfaire aux exigences de la norme. Une conduite d'air trop grosse pourrait causer un retard au niveau du serrage des freins et augmenter les distances de freinage, ce qui pourrait augmenter les risques d'accident pouvant entraîner des blessures ou des dommages matériels (ou les deux). Mesure corrective : Les concessionnaires devront actualiser et modifier les conduites du système de freinage à air comprimé.
