The problem
Mack is recalling 218 my 2006-2007 mr trucks. A check valve was omitted from the secondary supply port of the sr-7 spring brake modulating valve.
The risk
As a result, an air leak in the secondary or primary system may result in the park brakes inadvertently applying, increasing the risk of a crash.
The fix
Dealers will add a check valve to the secondary supply port of the sr-7 spring brake modulating valve and will also repair the sr-7 valve by applying a check valve repair kit as required for the bendix safety recall (please see 07e-037). The recall began on april 15, 2008. Owners may contact mack at 1-800-528-6586.
