Yep, brakes sometimes break but breaks don't have brakes.  ;)

To be honest, I would like to know if there is an alternative to the valve myself. I have sprung a leak on mine, nothing serious, and I really don't want to spend the $400+ price tag for a new one.

Sorry wesslegod, we just could not resist "jacking" with you a little! ;)

If I remember right, Heather came accross a similar issue with her 4door SAS Kick. Might be some topics about it around here...

Different applications, but I just eliminated all the stock proportioning valves on mix and match trucks and if the brakes were locking up too easy in the rear (tested on a gravel road with speed) then I added an aftermarket proportioning valve to dial it down.  You can't really predict these things that well when you are mixing different master cylinders with variable slave cylinders (especially after you have swapped out drums for rear discs.)  Remember that tire size can make a big difference too ... I found my Subby rear brakes locked up 38s a little too easy on the gravel (they were Ford dual piston 1 ton calipers) but were no problem with 44s. 

The worst case scenario is that you can have a master that just does not move enough volume for large pistoned (or dual pistoned) calipers ... this has not really been my experience though.  And I am not sure that you will find big volume enough differences in the hardware between Zuks and Toys. 

The factory proportioning valves (designed for a certain model master/slave combination and tire size) is unlikely to be the right thing for your new slaves and wheels.  I would recommend removing them and being prepared to buy a variable proportioning valve.  That said, you could always leave them in there and try it out as is (you haven't much to lose but a little time and the cost of blank fittings.)  You probably won't get a more detailed explanation than that because it really depends on your build (unless you are copying someone else's build.)

ok thanks thats more of the reply i was looking for the thing i was most concered with was the frunt breaks because thay go into the frunt p valve and was woundering if it would mess with them if i eleminated the frunt one i was planing on getting a ajustable p valve for the rear if thay locked up to much on hard breaking. thanks for your info it helps.

Thing is, you need a proportioning valve. If you are running equal pressure to the front and rear brakes the rear will lock or the front won't be as effective as it should be. My bet is to buy an adjustable aftermarket unit. Every body running different from stock tires and ride height should. I'm being a little hypocritical as I am running a lift, larger rubber and bigger front calipers. But if you are running a significantly modified brake set up and use it for a much road use you should consider it.
