    Questions on Master Cylinders, Rear Disc Conversions, and 3/4 ton swappin\'

    I figured I'd get all my questions answered at once:

    First some background - I have a '72 K5 that I want to swap my '75 K20 running gear into. While I have everything off, I figured I might as well put rear disc brakes in. So from there, do I have to upgrade my master cylinder?

    The '72 Master Cylinder is pretty scary looking without the power boost - is it safe to use this master cylinder with rear disc brakes?

    Thanks...

    I understand guys are getting away with using their stock master cylinder and running rear disks...

    I'll be trying it in a week or two myself... the only diff is my 72 is power brakes...

    id say upgrade to power brakes would help a lot.second every one ive seen post about the conversion say there is no problems after running the same prop valve and all thAT.they say the brake pedal is a little squishy but the truck still stops much better than drums.
