Possibility toggle-type tractor protection control valve may have been substituted for required push- pull type valve. This substitution would eliminate automatic protection of tractor service brake air supply in event of loss of trailer air. This loss, however, will not impair effectiveness of tractor trailer emergency brake system. (inspect and replace with correct valve where necessary. )
