    Good morning,

    I am having a heck of a time trying to find a brake master cylinder with a 1 3/4" bore and triangle 3 bolt pattern, for my old 1969 International Loadstar 1700 series. I have tried looking just about everywhere I can think of and no one has any. Does anyone here have any suggestions for possible alternatives in the event one cannot be located? The truck is only used as a farm truck on a primarily flat piece of property, so the brakes don't have to be "perfect", would just like to be able to slow down without yanking the e-brake.

    Any insight into possible solutions is much appreciated!
     
    bzinger Thanks this.

    What about building an adapter plate and adapting a more modern master cylinder
    Piece of 1/4 steel or smaller and drill holes mount it and tack weld 2 bolts to plate steel. Mount new cylinder to that.
    Drill center hole big enough for rod.
    I am assuming it is a dual circuit, or a single circuit?.

    I believe the first generation of Camaro used single non power assist master cyl
    Not sure about stroke though.

    Saw that one, it’s a 1.5 inch bore, mines the 1.75. I’ve ordered one, hoping it can be made to work.
