Posted on: 2009-05-04DescriptionTerex is recalling 17 my 2009 dfpr, dfpr sf, dfpr ca, dfp hd, lfpr and hft85-3 trailers equipped with haldex air brake system control valve. The rubber diaphragm used inside the quick release valve (qrv) may delaminate and may cause leakage levels past and/or through the diaphragm in excess of permissible specifications, or could cause a restriction in the air flow, thereby effecting pressure delivery to the service brakes and not allow the service brakes to release.
ConsequenceMalfunction of the air brake system could result in a vehicle crash.
