Hey guys,

I am buying a rear brake conversion to replace my wack drums. I know i need several things. Does anybody have experience doing this ???

Things I know i need:
Actual Rear Disk Conversion, rotors, etc...
Master Cylinder
Brake Booster
and a Proportioning Valve.
o...and SS Brake Lines

I have read several articles stating you need a proport. valve that says 4040 on it. I have looked around and all i can find are 3030 valves. WILL THOSE WORK ????

let me know asap, doing the conversion tomorrow.
