wilbur Posted January 8, 2017 Share Posted January 8, 2017 (edited) I put new shoes on the trailer with old drums which were in good shape,hardly worn. The front shoe by the pin is only making contact on half the shoe. so what I mean is 3/4 of the whole shoe is making contact. I dont recall this before. The mechanic at Mack said it was normal that the whole shoe would make contact once it wore in. Is this correct or I have the wrong shoes? They are Merritor Qs 4515Q is on each shoe. This is what I always bought. Thanks Edited January 8, 2017 by wilbur Quote Link to comment https://www.bigmacktrucks.com/topic/48282-trailer-brake-shoes/ Share on other sites More sharing options...
