Just a few quick ones to those that are running a disk brake rear on your Zook using the front rotors and calipers

Did you mod the master cylinder at all or just ad the proportioning valve ?

Have any used a proportioning valve from something else rather than a manual one ?

Thanks

Left the valve and MC alone and it works great. Excellent ballance and amazing stopping power. In fact, with the old SR and tires aired down, I could lift the back tires off the ground!

However, I'm running 11-1/2" disc on front with 3" piston calipers then stock Sami fronts on the rear axle. That's probably why the ballance is good.... :)

In muddy or real wet conditions I do get a little squeak from the rear disc because the residual pressure valve is still active. Only a slight anoyance... :p
