whats up sc guys. wondering if any of you know and can give me info on whether or not the sc masters are internally prop valved? by looking at them i would say that they are, very curious. trying to put my mind around upcoming brake projects on my gs. while checking out you guys abs deletes im not seeing anyone add in an external prop valve, so im assuming that its not integrated into the abs unit.

thanks in advance.

 

It sort of does. The master cylinder is setup, so the fronts brake before the rears will. It has 2 sets of springs inside that start releasing fluid into the front brakes before the rears. Each line also has it's own feed from the MC reservoir. I'm not sure if the ABS module has its own prop valve internally.

This is what the master cylinder rebuild kit looks like. Top spring is for the rears and bottom spring is for the front.

just for information compiling purposes. it does seem as though the master IS the prop valve...yes indeed, now im getting excited
