{"source":"tc","country":"ca","campaign":"1996122","date":"1996-08-06","owner_notified":null,"manufacturer":null,"component":"Brakes","summary":"Note: certain trucks equipped with Westport WS-16 front axles with Eaton ES 16.5 X 5 or 16.5 X 6 brakes. In these combinations the front brake return spring contacts the hub after about 20% wear of the brake shoes. Further wear of the brake material will lead to wear of the return spring and the spring may eventually fail prematurely. Pieces of the failed spring may then lodge in the brake cam causing either the affected brake to stay applied when the other brakes have been released, or stopping the affected brake from applying when the other brakes are applied. Either of these scenarios may cause the vehicle to be pulled in a lateral direction off the road or into on-coming traffic. Correction: Front brakes will be modified by installing horse collar/double return spring kits.","consequence":null,"remedy":null,"notes":null,"mfr_campaign":"W-9606","part_number":null,"units":206,"completion":null,"do_not_drive":null,"park_outside":null,"notification":"Safety Mfr","french":{"component":"Freins","notification":"Sécurité - fabricant","summary":"Nota: Vise certains camions équipés de l’essieu avant Westport WS-16 et des freins Eaton ES 16.5 × 5 ou 16.5 × 6.Lorsque ces deux accessoires sont combinés, le ressort de rappel des freins avant se met à entrer en contact avec le moyeu quand les sabots de freins sont usés d’environ 20 %. Toute usure additionnelle des pièces de freins pourrait alors entraîner l’usure du ressort de rappel et, éventuellement, son bris prématuré. Des débris du ressort pourraient alors se loger dans la came du frein, ce qui pourrait avoir comme conséquences que le frein touché reste appliqué quand les autres freins se desserrent ou qu’il ne s’applique pas quand les autres s’appliquent. Dans un cas comme dans l’autre, le véhicule peut être déporté sur le côté et sortir de la route ou être projeté vers les véhicules circulant en sens inverse.  Correction: On devra modifier les freins avant en posant des ressorts de rappel doubles en collier de cheval."},"vehicles":[{"year":1988,"make":"WESTERN STAR","model":"4800","vehicle_id":"1988_western-star_4800","match":"exact","built_from":null,"built_to":null},{"year":1989,"make":"WESTERN STAR","model":"4800","vehicle_id":"1989_western-star_4800","match":"exact","built_from":null,"built_to":null},{"year":1990,"make":"WESTERN STAR","model":"4800","vehicle_id":"1990_western-star_4800","match":"exact","built_from":null,"built_to":null},{"year":1991,"make":"WESTERN STAR","model":"4800","vehicle_id":"1991_western-star_4800","match":"exact","built_from":null,"built_to":null},{"year":1992,"make":"WESTERN STAR","model":"4800","vehicle_id":"1992_western-star_4800","match":"exact","built_from":null,"built_to":null},{"year":1993,"make":"WESTERN STAR","model":"4800","vehicle_id":"1993_western-star_4800","match":"exact","built_from":null,"built_to":null},{"year":1994,"make":"WESTERN STAR","model":"4800","vehicle_id":"1994_western-star_4800","match":"exact","built_from":null,"built_to":null},{"year":1995,"make":"WESTERN STAR","model":"4800","vehicle_id":"1995_western-star_4800","match":"exact","built_from":null,"built_to":null},{"year":1996,"make":"WESTERN STAR","model":"4800","vehicle_id":"1996_western-star_4800","match":"exact","built_from":null,"built_to":null}],"may_apply":true,"as_of":"2026-10-19","lookup":{"nhtsa":"https://www.nhtsa.gov/recalls","tc":"https://wwwapps.tc.gc.ca/Saf-Sec-Sur/7/VRDB-BDRV/search-recherche/menu.aspx?lang=eng","maker":null},"attribution":["Contains information licensed under the Open Government Licence – Canada."],"url":"https://open.wenmarpro.com/recalls/tc/1996122"}
