    Hi, i just converted my 92 gmc sierra half ton to a three quarter ton when i straight axled it with some 78 ford axles. What i want to know is what are the best master cylinders that i could run for this conversion?

    this just doesn't make any sense, you should run the master cylinder that came with the truck originally.

    i would match the master to the brake system you are using, old one or converted one

    If old one from "donor" doesn't work there are plenty of companies out there that sell brake kits or Adapter kits. Maybe looking into those or even contacting them would be a good start. Due to different types of conversions, the Off-Road aftermarket is huge.

    the brakes are just a set of hydraulics, what most big off roaders do is purchase an adjustable proportioning valve to fine tune how much pressure you want where. with brakes start high then back off pressure. in the race cars we install knobs in the seat to adjust on the fly
