Hydroboost Master Cylinder Info Needed

[pu70]

I have a hydroboost and a master cylinder from a 92 Astro and need some info about the master cylinder. There are 2 ports cominig out the side of the master cylinder. Which one is for the front brakes and which one is for the rear brakes? Thanks

Unfortunately, I don't have a '92 to compare. You can trace the lines to find out, or wait for a different answer. Typically, the larger fluid reservoir on the master cylinder is for the front (disc) brakes, and the line adjacent to the larger reservoir would route to that axle.

Thanks. I couldnt trace the lines back because they went into sime kind of ABS thing.
