75T Posted May 11, 2009 Share Posted May 11, 2009 What brand did mack use? it is not a Bendix E-3 . It don't look even close. It is about 3 1/3 to 4'' in dia. about 4" tall to the plunger. 6 - 5/16 bolts thru valve, 3 go into the footpedal base. air feed line comes in the bottom . one to the tractor protection valve, third to the relay for the drive wheels....... Is it possibly a Wagner?? any help would be helpful. Thanks in advance 75-T Quote Link to comment https://www.bigmacktrucks.com/topic/9361-b-70s-treadle-valve/ Share on other sites More sharing options...
theakerstwo Posted May 11, 2009 Share Posted May 11, 2009 It should be a Bendix model E 1 or E 2.That will be a single brake circuit. Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/9361-b-70s-treadle-valve/#findComment-35097 Share on other sites More sharing options...
