1956 Plymouth brake help

Muffin1 Posted 2019-06-14 6:01 PM (#583454) Subject: 1956 Plymouth brake help Veteran Posts: 242 Location: Michigan I am putting Disc brakes on the front of my 56 and leaving the drums on the back. Should I put a proportioning valve in for the rear brakes Thanks Alex Shep Posted 2019-06-14 8:39 PM (#583461 - in reply to #583454) Subject: Re: 1956 Plymouth brake help Expert Posts: 3396 Location: Chestertown, NY ( near Lake George) Yes, and make sure the master is a disc/drum unit, you can use an adjustable prop valve or the more common disc drum fixed prop valve.
