We need either a drum brake system or a hydraulic brake valve.
Our current Drum: http://www.surpluscenter.com/item.asp?catname=hydraulic&item=9-9003
Options for drum brake:
Fits our drum, but costs $560 : http://www.jegs.com/i/Currie/272/96226/10002/-1?parentProductId=756792
Does not fit, but demonstrates that there may less costly options: http://www.surpluscenter.com/item.asp?item=28-1324&catname=
Options for hydraulic brake valve:
Still need to determine price and circuit : http://www.hydrotech-bg.com/common/d_images/src/file/PDF/E4-ACCESSORIES.pdf - See Overcenter valves with brake control

Brake Research
Discusses several brake systems, their advantages and disadvantages, as well as how to trouble shoot them.
There are two commonly used types of brakes. Drum-Brakes, and Disk-Brakes.
