I am looking to get some hydraulic pedals and make them adjustable to allow shorter people to drive my rail. It has drums on all four corners with the front wheel cylinders in the back and the rear wheel cylinders in the front to change the bias as stated in the Baja Bugs and Buggies book. My question is what type of master cylinder should I get? Will the bigger diameter two wheel master work with my setup or will I need to get the 4 wheel master?

by 4 wheel, do you mean late model bug dual circuit M/C? if so then yes, i would, because if one side of the mastercylinder fails, or you have a ruptured line somewhere, you will still have brakes on the opposite side (front or rear).

How will you make them adjustable?

pick up a CNC dual master pedal assembly. they have a bias adjust bar between the two master cylinder plungers on the pedal. set it up and you are good to go. if you would like to be able to adjust on the fly for whatever reason they have a cable remote bias adjuster that attaches the the bar and you can mount the know on your dash or wherever else you may like

I'd prolly go for the CNC pedal assemblies. there are many combinations to choose from.

To make them adjustable they make brackets that move and you use rubber or braided lines to allow for the movement. They also make and an adjustable bar for the accelerator cable.

I was looking at these. This says for four wheels

This one says for two wheel

CNC does make a ton of different types of pedals. Thats the reason for my question because i am not sure which one is right. I don't have disks or anything fancy so do i really need the four wheel setup. But like BugMan114 said you'd have a back up if you spring a leak. which direction do i go?

Definately get the 2 circuit setup, As stated before, if you dont have an E-brake, its safer and the balance bar is great to have.
You might need a specific bore for drums, so you should find out what bore is required for the stock drum setup.
Your also going to need adapters to go from the 1/8 CNC threads to the VW metric threads. This is where I got most of my fittings:

What I did: Neal makes the best slide kit hand for the brake masters.

That is pretty much the setup I want to have. What did you use to hook up the accelerator cable that allows it to move?

Neal makes an adjustable end for the Morse cable end with an easy to adjust thumb screw onto a threaded rod thingy. Works great!

I purchased mine from this company here:

Make sure you find out the correct bore size for your pedals before ordering. I would recommend referring to CNC's website for all the correct information required. I received some poor advice and ended up with the wrong bore and it cost me $$$$.
